Genetics of fertility restoration and agronomic performance of CMS based hybrids in pigeonpea
Abstract:
In the study, CMS based hybrid combination involving two male sterile lines (Cajanus cajanifolius) and four restorer lines in pigeonpea (Cajanus cajan) were studied to determine the genetics of fertility restoration in pigeonpea (Cajanus cajan L. Millsp.). Based on the pollen fertility and pod setting, F2 segregating populations were categorised. Out of two major genes governing the fertility restoration, one gene segregated in the ratio of 9:3:4 whereas the second gene in 12:3:1 due to the allelic differences. The ICPA 2043/ LRG 41 and ICPA 2043/NDA 1 hybrids fits best for agronomical aspects as they showed earliness with respect to flowering and maturity having more number of pods plant-1, increase in pod length along with more seed yield plant-1. CMS system is a useful tool serving to increase seed yield production of various crops and consummate the demands of increasing populations.
