Abstract

Nineteen genotypes of linseed (Linum usitatissimum L.) were evaluated for the three environments during 1989-90 to 1991-92 and stability for parameters studies for yield and yield attributes. G XE (linear) interaction was significant for number of branches/plant and highly significant for plant height, number of seeds/ capsules and number of capsules/plant. The environment III (1991-92) gave the highest yield and was favourable for most of the characters. Based on D2 values 19 genotypes were grouped into seven clusters. Twelve genotypes were sorted out on the basis of stability and genetic divergence for yield and yield attributes.
