tailieunhanh - Improvement in seed yield and related traits of linseed genotypes (Linum usitatissimum L.) through various selection parameters in mid-hills of North-West Himalayas

Forty five linseed genotypes were subjected to study the interrelationship among the traits at the Experimental Farm of the Department of Crop Improvement, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, during rabi 2015-2016. The genotypic and phenotypic correlation coefficient obtained between different traits was similar in direction, while in magnitude, genotypic correlation was higher than the corresponding phenotypic correlations for most of the traits. Seed yield per plant had maximum significant and positive genotypic and phenotypic association with biological yield per plant followed by harvest index and seeds per capsule. Harvest index plant contributed indirectly through plant height followed by technical height and biological yield per plant has maximum indirect effects through capsules per plant on seed yield per plant. Principal component analysis (PCA) showed that seed yield per plant, harvest index, biological yield per plant seeds per capsule and capsules per plant were found in same group. | Improvement in seed yield and related traits of linseed genotypes Linum usitatissimum L. through various selection parameters in mid-hills of North-West Himalayas 2017 6 2 1559-1566 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 2 2017 pp. 1559-1566 Journal homepage http Original Research Article http Improvement in Seed Yield and Related Traits of Linseed Genotypes Linum usitatissimum L. through Various Selection Parameters in Mid-Hills of North-West Himalayas Satish Paul Nimit Kumar and Pankaj Chopra Department of Crop Improvement CSK Himachal Pradesh Krishi Vishvavidyalaya Palampur-176062 India Corresponding author ABSTRACT Keywords Forty five linseed genotypes were subjected to study the interrelationship among the traits at the Experimental Farm of the Department of Crop Improvement CSK Linum Himachal Pradesh Krishi Vishvavidyalaya Palampur during rabi 2015-2016.
