Capacity Enhancement

 One female Ph.D. student from Tanzania registered with Sokoine University of Agriculture

 Two Ph.D. students from MAU Parbhani, and OU have started research program

Farmer Friendly Literature-ESA

Malawi • Manual for pigeonpea production in

English & Chichewa published

Tanzania • A draft information bulletin in

Kiswahili is in progress in Tanzania.

Information Bulletins- Asia 1. Tur Lagwad Aani Bijotpadan

•  Marketed by seed companies

•  Medium duration

•  Resistant to diseases

Linkage between genomics &

Marker – based purity test

Lessons Learnt  Develop region - specific hybrids/varieties

 Study abiotic stresses (drought and water-logging ) to address challenges of climate

  Phytophthora blight becoming important

 Broad-based training of farmers essential

 Enhance links with seed comp

 Enhance links with genomics

Challenges Strategies (ASIA)

Yield plateau Breed high-yielding hybrids Narrow planting window

Photo –thermal insensitivity

Insect damage Introgression from wild spp Seed quality Maintenance breeding Water-logging Identify resistant genotypes Drought Extra-early lines, hybrids Pb, Fusarium wilt, Use DOMINANT gene for

wilt resis; new res sources

Challenges Strategies (ESA)

Yield Breed high-yielding var. Inadequate Goverment

support

Better leverage & representation

Insect damage Introgression Demand & supply gap

Strengthen seed system

Linkages among stakeholders

Strength linkages

Training Enhance opportunities

Vision for Phase II  Introduce pigeonpea in new niches (low &

med hills)

 Expand FP- varieties in project areas

 Enhance genetic variability by exploiting

- Genes from wild species

- African x Asian origin crosses

 Initiate research on water- logging & early season drought

Vision for Hybrid Breeding - increase area**

- diversify parents**

- expand partnership base** - Introduce hybrid tech. in ESA - specific training (students, seed

production, quality maintenance) - Use genomics tools (one crop / year)

Low and mid hills (up to 2200 m) A potential niche

for expanding pigeonpea area

Potential area = >500,000 ha Technology is available

Example;; Nainital, 1630 m

Rudrap’g, Pigeonpea at 2200 m
