Achievements of

Pigeonpea Hybrid Projects

Supported by ISOPOM & NFSM

Technologies Developed[ under these successful projects ]

• CMS systems developed (20 lines)

• Elite hybrids developed (10 hybrids)

• High yield demonstrated (30- 44 qtl/h)

• Seed technology developed • Seed cost estimated (Rs.10.5 / kg)

• Proc. & utilization trials conducted

• MAJOR CONSTRAINTS identified

Partnerships in Development

• ICAR Institutions = 16

•Other countries = 3

• Public seed companies = 4

• Private seed companies = 15

Problems Identified (purity)• No quality control by producers

• Inadequate isolation

• Inefficient monitoring & roguing

• Seed mixing accidental & deliberate

• Lack of grow-out tests

Steps to Control Seed Quality• Produce high quality breeder seed

• Efficient monitoring & roguing

• Seed quality kit developed (biotech.)

• Seedling marker incorporated in parental lines

• Minimum isolation distance 500 m• Training of seed growers intensified

Future Plans• Strengthen links with partners

• Exchange of elite lines

• Emphasis on disease resis. & yield

• Locally adapted hybrids

• Strengthen training & supervision

• Fine tune production tech.

• Release at national /state levels
