- Abstract
In this study, we investigated the correlations among seed yield and yield components and direct and indirect effects of the yield components on seed yield in linseed, Linum usitatissimum L. We conducted replicated experiments during 2 consecutive years of rabi seasons, 2010-11 (S-I) and 2011-12 (S-II) involving 18 dual-purpose type linseed genotypes to assess genetic variation for seed yield and yield components, quantify interrelationships among them, and determine direct and indirect effects of yield components on seed yield through path coefficient analysis to identify traits for indirect selection of seed yield. Highly significant (P ≤ 0.01) genotype × environment interaction was observed for seed yield/plot and the seed yield components capsules/plant, 1000-seed weight, biological yield/plot, straw yield/plot, days to flower initiation, days to maturity, plant height, technical height, number of primary branches/plant and number of secondary branches/plant, indicating substantial environmental influence on these traits for these genotypes. Data for these traits were analyzed separately for each year revealing significant (P ≤ 0.01) differences among genotypes at both years for each of these traits. Highly significant and positive phenotypic correlations with seed yield/plot were found for biological yield/plot and straw yield/plot in both the seasons. Path coefficient analyses revealed that biological yield/plot had the greatest positive direct effect on seed yield/plot in both the seasons. Ample genetic variability was present among the linseed genotypes studied to allow breeding improvement of seed yield. Selection for biological yield/plot followed by capsules/plant and seeds/capsule would be the most effective means of indirectly selecting for higher seed yield within these genotypes.
