Studies on genetic variability in segregating generation of soybean [Glycine max (L.) Merrill]

An investigation was carried out at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif 2006 to analyze the extent of variability in F3 segregating generation of cross JS-93-05 x DSb-1 of soybean. All the segregants in the population were classified based on leaflet shapes viz., oval, ovate and lanceolate leaflet types. It was observed that considerable range of variation was exhibited by all the leaflet types. The high heritability was observed for traits viz., plant height, number of pods per plant, specific leaf weight, harvest index and 100-seed weight in oval leaflet types. In addition to these characters number of branches, days to flowering and days to maturity in lanceolate leaflet types exhibited high heritability.
