Abstract

The experiment was carried out to estimate genetic variability among thirty-five genotypes of oilseed Brassica, including 20 F2s/F3 populations derived through interspecific hybridization and 15 parents, during rabi 2015-16 and 2016-17. Pooled analysis showed that considerable variability was observed among F2s/F3s and parents for all the fourteen characters. Variation due to “location x treatment” was significant only for secondary branches & oil content. The estimates of GCV and PCV were comparatively higher for plant height, primary & secondary branches/plant, number of siliquae per plant, siliqua length, seeds per siliqua, test weight, seed yield per plant and oil yield per plant. High estimates of heritability were recorded for all the characters. The estimates of genetic advance (GA) were also recorded high for number of siliquae per plant and plant height. Number of siliquae per plant showed high heritability (92.4 %) together with high genetic advance (219.1%) and genetic advance as percentage of mean (78.8). Traits like siliquae per plant and plant height might be considered as high potential traits for effective selection for further crop improvement in Brassica spp.
