Crossability relationship and influencing factor among linseed genotypes over the agro-climatic conditions in mid hill of North West Himalayas

Published on

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.
