Genetic variability among B & R lines on milo and maldandi cytoplasm across the years in rabi sorghum [Sorghum bicolor (L.) Moench]
The genetic study was conducted among 68 genotypes comprising restorers and maintainers on milo and maldandi cytoplasm. Among the lines, IS 12735, DSMR-8, IS 33353 and IS 24175 exhibited full restoration on milo and DSMR-4 and DSMR-8 on maldandi. The lines viz., IS 30383, IS 29335, IS 29914, IS 8012 and IS 12308 exhibited perfect maintainer reaction on both milo & maldandi. High heritability and genetic advance were observed for most of the traits. G x E interaction was also found to be high for the majority of the traits. A high amount of genetic variability among the population indicated an increased opportunity for the selection of restorers, maintainers as the variation is heritable.
