Genetic analysis of grain yield in pigeonpea using male sterile lines

Three male sterile pigeonpea (Cajanus cajan) lines (MS-3A, MS-4A and MS-Prabhat) were used as female parents and pollinated by 7 fertile testers, chosen for their wide genetic and geographical diversity. The 10 parents and 21 F1 hybrids were planted in 1982. Data for yield and 6 other agronomic traits were recorded on randomly selected fertile plants and analysed for combining ability. GCA variance was higher than SCA for yield, pods/plant, seeds/pod, seed size and days to flowering. MS-Prabhat was a good general combiner for dwarfness, earliness and seeds/pod. Tester C11 was the best general combiner for yield (54 g/plant)., 14 ref., Three male sterile pigeonpea (Cajanus cajan) lines (MS-3A, MS-4A and MS-Prabhat) were used as female parents and pollinated by 7 fertile testers, chosen for their wide genetic and geographical diversity.
