Online published on 18 January, 2019. Abstract To determine the response of different genotypes, environment on crossability and seed formation efficiency, four genotypes viz., (T-397, Chamble, Kangra Local and HimAlsi-2 as female and HimAlsi-1 and Nagarkot as male were used to make eight crosses in linseed. Maximum crossability 92.06% and seed formation efficiency 63.48% was recorded at Palampur, 91.04% crossability and seed 63.17% formation efficiency was observed at Kangra, indicated Palampur as the best location for both the parameters. Significant genotypic and environmental variations were observed for crossability and seed formation efficiency at two agro-climatic conditions. Among parental genotypes, T-397 (female) and HumAlsi-1(male) responded significantly better for both the parameters due to significant positive GCA effects at both locations.
