  35. 35. 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
  36. 36. Challenges Strategies (ASIA) Yield plateau Breed high-yielding hybrids Narrow planting Photo –thermal insensitivity window 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
  37. 37. Challenges Strategies (ESA) Yield Breed high-yielding var. Inadequate Better leverage & Goverment support representation Insect damage Introgression Demand & supply Strengthen seed system gap Linkages among Strength linkages stakeholders Training Enhance opportunities
  38. 38. 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
  39. 39. 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)
  40. 40. Low and mid hills (up to 2200 m) A potential niche for expanding pigeonpea area Potential area = >500,000 ha Technology is available
  41. 41. Example;; Nainital, 1630 m
  42. 42. Rudrap’g, Pigeonpea at 2200 m
  43. 43. Thanks for your attention
