Morphology and genetics of a new found determinate genotype in chickpea

摘要: Chickpea (Cicer arietinum L.) is an indeterminate plant and produce excessive vegetative growth that acts as a competitive sink for developing pods resulting in reduced fruit set whenever soil moisture temperature conditions are favorable. Determinate genotype was so far not available the world chickpea germplasm. needed to change its architecture order achieve breakthrough productivity stabilize yields cool long-season sub-tropical environments of semi-arid tropics. A true breeding determinate developed first time programme. The objectives were study: (i) new found BGD 9971 important characteristics (ii) genetics habit it. bushy, compact dwarf morphology; stem terminated by flower produced 1–4 seeds per pod. segregation patterns F2 F3 two crosses (BGD 72 × 128 9971) involving parents have shown governed recessive genes. genes determinacy designated dt1 dt2. homozygous both alleles (dt1dt1dt2dt2) phenotype. utilization identified newly has major impact on better adaptation climate, high fertility irrigated environments.
