Five linseed (Linum usitatissimum L.) genotypes were evaluated for four years (1993-98) for seed yield. LS-49, LS-75, LS-73 and LS-29 demonstrated 24.82, 18.23, 29.92 and 3.09 % higher mean yield compared to a commercial variety Chandni, during 1993-94 and 1994-95 at the research station. Mean yield of 11 trials conducted over different locations in Punjab during 1996-97 and 1997-98 showed the highest yield of LS-73 followed by LS-49, LS-75 and LS- 29 compared to 677 Kg ha-1 of Chandni. In three of the 11 trials, LS-49 ranked first while all other genotypes each enjoyed first position in two trials, indicating considerable influence of location on genotypic performance. Ls-49 was the most stable genotype amongst five and it showed responsiveness to agronomic manipulation to obtain higher yield.
