Around New York...Statewide (Tim Martinson)After a blistering hot day (mid ‘80s to ‘90s) this past Tues-day, the rains came and temperatures dropped. The first frost warning for Central New York is in place for tomor-row morning. Leaves of wild grapes are turning yellow. In short, it appears we are transitioning to cooler fall weather, following several weeks of mild and (mostly) sunny weath-er, ideal for ripening.

Fruit composition and growing degree-days are starting to catch up to last year (see figures in the Lake Erie and Hud-son Valley notes). In several varieties, soluble solids gained roughly 1° Brix, and titratable acidity (TA) changes varied from 0 to -4.5 g/l (Vidal blanc).

The cold-climate Minnesota varieties are being harvested – with soluble solids ranging from 20-22° Brix (range last year was 22-24° Brix), and TAs were still higher than last year, ranging from 12-17 g/l (10-13 last year). Most Frontenac and many Marquette blocks have been harvested, but the La Crescent blocks that we are monitoring are still hanging.

Among the other hybrids, early varieties Seyval blanc, Marechal Foch, Vignoles and most Cayuga White have been harvested; Traminette has higher brix (19.6° Brix) and acids below 10 g/l (similar to last year), while Vidal blanc lags 2° Brix behind 2018, with higher acids (but still below 10 g/l @ 9.8). The remaining Vignoles samples are from a research block at AgriTech.

The three Concord blocks are averaging 16° Brix, a gain of 0.9° Brix from last week. The Concord harvest will soon be in full swing. Our lone Catawba block is still lagging at 14.6° Brix, but acids dropped by 4 g/l last week. Niagara harvest is largely complete – and our sample from Lake Erie is at 16.9° Brix.

For vinifera varieties, only our Gruner Veltliner (teaching vineyard) and Sauvignon blanc (Long Island) blocks have been harvested (along with two Hudson valley Pinot noir blocks). Midseason varieties like Chardonnay and Pinot noir are leveling off, with Chardonnay at 18.9° Brix (up 0.3 from last week;) and TAs dropping by 0.3 g/l (avg. 9 g/l). Pinot noir average at 20.6° Brix (+0.6° Brix, -0.7g/l TA) is 1.3° Brix higher than last year, but acids are 2.0 g/l higher than 2018.

Cabernet franc, at 19.7° Brix and 8.2 g/l TA averages is close to the 2018 average – but note that the Long Island and SW Hudson valley samples have lower acids and higher brix than Finger Lakes samples.

Riesling overall is at 17.5° Brix and 10.0 g/l – very close to 2018 averages (17.4° Brix; 9.1 g/L). But the range is wide (15.1 to 19.6° Brix; TAs around 7.5 in the HV, 8-12 g/l in Western NY). At least a few of the lower numbers may be associated with loss of foliage to downy mildew.

The bottom line, however, is that after a slow start, fruit composition is catching up to 2018 – a fact attributable to the several weeks of warm and sunny weather we have ex-perienced.

In the Cornell research vineyard, we harvested a group of varieties that we collectively call the ‘miscellaneous whites’ (Table 1). Due to a limited labor pool and re-stricted by the government work day, we have to plan and space out the harvesting of the 35 varieties in our vineyard. This means some are picked a bit early, some are picked at peak ripeness and some are a tad over-ripe. Regardless, we get a nice preview of viticultural characteristics and fruit quality. Below are numbers and comments from our harvest. On Oct. 2, we started Chardonnay harvest. The fruit has been beautiful – golden and somewhat translucent with minimal clus-ter rot. Clusters are big, especially clone 5. Vines on C3309 rootstock have larger clusters vs. MG101-14 and own-rooted vines.

Lake Erie (Jennifer Russo) Going into the first week of Concord harvest, we are seeing sugar levels normally found at the end of the season. The weather in the Lake Erie region shifted from a very long stretch of warm sunny days to cool wet conditions. The change in weather has not slowed sugar accumulation as we have seen another jump this week. Finding Concords that meet the minimum 15 °Brix standard has been easy for most growers.

The ‘berry curve’ shows this week’s samples ranged between 16.4-17.2 °Brix in our phenology block, which were gains ranging from 0.5-1.2 °Brix accumulation over last week. Here at CLEREL the Concord harvest is underway and we are picking our first load of the year.

Area processors are reporting final Niagara averages ranging from 15.0-15.54 °Brix and Concord average sugar solids thus far around 16.54°. Berry Curve: Re-cent rains have contributed to another jump in berry size.

Growing Degree Day accumulations this season have been tracking lower than the average of the past ten years. However, weather in our area last week has helped close the gap on the GDD deficit.

The past week’s weather for CLEREL as of 9:00 am on Thursday, October 3rd, had an average air temp of 64.0 °F, with an average max temperature of 70.7°F, which is 0.90° lower on average than the beginning of the month. The average minimum temp of 56.8 °F was only 0.10°lower than the first week of September.

I traveled down to southeast Pennsylvania this week to see the Spotted Lanternfly quarantine zone in person and talk to researchers and growers about their expe-rience and what they have learned thus far. LERGP will be posting my experience in podcast form so you can see the struggles this invasive species is presenting to our industry and research that is happening to aid all of our efforts. We will update you as they become available.

To keep abreast with what is happening in the Lake Erie region, check out the Lake Erie Regional Grape Program Extension team’s weekly podcasts at http:// lergp.com/podcasts/. This week’s podcast covers how the CLEREL staff is manually building a spatial Brix map to validate a sensor we developed.

Finger Lakes (Hans Walter-Peterson)A wise man once said (or maybe sang) “You can’t al-ways get what you want”. While that’s true most of the time, the month of September was pretty close to almost exactly what growers wanted. And for the most part, that has meant dry and warm. The Finger Lakes ended up with less than 2” of rain for the month of September – well below our average of about 3.6” dur-ing the month.

As a result, very little in the way of bunch rots is show-ing up in most vineyards so far, and what rot is out there is mostly “clean” botrytis, meaning there is very little sign of sour rot development at this point. This is some good news after a season that has had its share of challenges, but harvest is far from finished at this point. Pinot gris, Chardonnay, and Pinot noir have been com-ing off the vines over the last week, along with most of the remaining Cayuga White. We also harvested our Lemberger at the Teaching Vineyard this week, along with Grüner Veltliner. While a few very early loads might have already come in, the bulk of the Concord harvest will be starting in the next few days for the Fin-ger Lakes. Yields are reported to be somewhat lower than anticipated so far for many varieties.

The weather took a major turn late Tuesday afternoon, and within 24 hours temperatures dropped from close to 90 degrees F to around 55. The outlook for the next several days looks more like what we expect this time of year, with much cooler temperatures and some more frequent chances of rain, which will slow down the ripening machine a bit. There is the potential for a frost or freeze in the southern portion of the Finger Lakes region on Saturday morning – and that’s some-thing we definitely don’t want.

The GDD shortfall vs 2018 year-to-date has narrowed by about 50 GDDs across all of eastern New York since last week (Figures 1 & 2). Champlain Valley is still lag-ging the most and isnow 350-450 GDDs behind 2018.

Figure 3, comparing 2018 and 2019 Brix, shows that the lower Hudson Valley vineyard blocks are slightly ahead of 2018, despite the GDD difference. Blocks with no data have been been harvested. Blocks with 2019 data but no 2018 data, are blocks that are still waiting to be harvested, but were harvested earlier last year.

Preliminary results from “Loose-Clustered Vignoles”

clonal trialTim Martinson, Janet van Zoeren, Terry Bates,

and Gan-Yuan Zhong

Standard Vignoles (Top row, labeled R53V30) compared to eight ‘loose-clustered’ clones in 2019

BackgroundAlthough Vignoles is prized as a superior variety in terms of its wine attributes, it is also known for its sus-ceptibility to fruit rots – especially botrytis and sour rot. Its clusters are tight, berry skin is thin, and berries are prone to splitting.

These attributes led Amanda Garris, former USDA sci-entist with the Grape Genetics Research Unit at Cornell AgriTech, to look at ways to reduce cluster compact-ness. So around 12 years ago, she collected dormant canes and subjected them to different doses of radia-tion to induce random mutations.

Around 1,000 different buds were grafted and planted at the Cornell Lake Erie Research and Extension Labo-ratory (CLEREL). Over the next five years, USDA sci-entist Peter Cousins evaluated each plant for its cluster characteristics.

Most had the tight clusters characteristic of Vignoles, but a handful (two handfuls?) had mutations that af-fected the clusters – and made them looser.

In 2016, we selected eight of these, propagated and grafted them, and established a replicated planting at CLEREL. For the past two years, we’ve rated them for fruit rots (incidence and severity) and cluster compact-ness (number of berries per centimeter of rachis). This year we also evaluated yield.

ResultsRot ratings in 2018 showed that all eight of the clones had substantially lower incidence (the % of clusters with any disease) and severity (% of cluster area or crop affected by sour rot or botrytis) than the ‘standard Vignoles clone.

1. 2018 Data. The standard clone (R53V30, shown in red) had about 90% of clusters with sour rot/botrytis, and 42% of the cluster area overall affected. The loose-clustered vines varied in incidence (range: 10-76%) – a reduction of 11 to 88%) and severity (range 3% to 27% - a reduction of 35 to 88%) compared to the standard.

Page 6

2. 2019 Data. Results were similar in 2019. Although the order of incidence and severity among the loose-clustered clones varied, similar levels of reduced in-cidence (40-83% reduction) and severity (54% to 86% reduction) were observed.

3. Cluster compactness in 2019. We weighed clusters and a sample of berries to determine berries per clus-ter – and measured the total rachis length from the first branch to the tip, and also the ‘wing’ length. This gave us a measure of cluster compactness (number of ber-ries per cm of rachis). Although there was some varia-tion, in general the fewer berries per cm we found, the lower the incidence and severity of the fruit rots. Clus-ter weight itself basically followed the same pattern.

Note that the clones in the following figures are ar-ranged in the same order as the rot incidence figures.

4. Yield. Less compact clusters tend to be smaller clus-ters, as well as having less fruit rot. So how does that affect overall yield? We weren’t able to hand-harvest all nine treatments, but did harvest the standard plus four of the loose-clustered clones. Yield was numeri-cally lower than the standard in all of the four clones, but only one of them (R62V78) was statistically lower (error bars not overlapping with the standard). On a per-acre basis, the range of yield for the standard and other three clones was from 4.5 to 5.7 Tons/acre at stan-dard 8x9 ft spacing.

Implications. These results look promising. But will the wines still taste like Vignoles? That is a question we will be pursuing with wines made from the four Loose-clustered clones and the standard Vignoles clone this year.

2019 Lake Erie Concord Berry Curve (Terry Bates)

Concord berry weight and juice soluble solids continued to climb last week; however, the rate of both slowed given the weather conditions and time of year. The fresh berry weight did not climb as much as expected because of the sunny and dry conditions the past two weeks. I still think Concord berry weight has the potential to jump because of the rain the Lake Erie re-gion is getting this week. Juice soluble solids are still tracking with the long term mean and averaged 16.6° Brix in the CLEREL phenology block.
