Genetic variation and characterization of different linseed genotypes (Linum usitatissimum L.) for agro-morphological traits
Article Main
Abstract
Forty five linseed genotypes (local collection) were subjected to study the genetic variability at the Experimental Farm of the Department of Crop Improvement, CSK Himachal Pradesh KrishiVishvavidyalaya, Palampur, during rabi 2015-2016. Analysis of variance revealed that the differences among all the genotypes were significant for all the traits. Mean performance of genotype KLSA-15 for seed yield recorded highest contribution of 3.69 grams. The PCV values were greater than the GCV values for all the traits studied indicating that the apparent variation is not only due to genotypes but, also due to the influence of environment. The highest PCV (64.17) and GCV (64.09) were found for biological yield per plant. Higher estimates of PCV and GCV were obtained for primary branches per plant, secondary branches per plant, capsules per plant, biological yield per plant, harvest index (45.94 and 44.60) and seed yield per plant (52.39 and 50.94). All the characters studied in the present investigation expressed high heritability estimates ranging from 62.95 to 99.77 percent for technical height and biological yield per plant respectively. It was revealed that most of the traits under study showed low genetic advance, high heritability (94.23) and high genetic advance (31.06) was recorded for harvest index indicating predominance of additive gene action for this character. Simple selection based on phenotypic performance of this character would be more effective. The cluster analysis showed that the genotypes were placed into four clusters, showing inter-cluster divergence, which is important for future hybridization programme.
