ABSTRACT
The present experiment on linseed (Linum usitatissimum L.) was conducted in line x tester design with 4 lines and 3 testers, during rabi 2014-15 at Experimental Farm of the Department of Crop Improvement, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, India, to examine the correlation among various important economic traits for the purpose of genetic improvement and their effect in the population. The highest positive and significant genotypic and phenotypic correlation was observed for seed yield per plant with biological yield per plant in parents, F1s and F2s generations. Positive and significant correlation in parents observed for seed yield per plant with plant height, technical height, straw yield per plant, seed yield per plot and 1000 seed weight whereas in F1s hybrids and F2 generation the correlation for seed yield per plant was positive significant with technical height, straw yield per plant, seed yield per plot, 1000 seed weight and harvest index indicating selection for these traits would subsequently lead to increase in yield.
Key words :
Line × testers, Linseed, Genotypic & phenotypic correlation, Yield attributes.
