Variability, Heritability and Genetic Advance Studies of Linseed (Linum usitatissimum L.) Genotypes at Vindhya Region of Madhya Pradesh, India

Linseed genotypes were grown in Completely Randomized Block Design (CRBD) at AKS University, Satna, during Rabi season on November 2022. The ten quantitative characters of 15 linseed cultivars studied, data were collected and estimated for variance, genetic variability, heritability and genetic advance. The design of the experiment indicated highly significant differences for all the characters due to treatments. The analysis of variance of fifteen genotypes of linseed, indicated the existence of sufficient amount of variability among genotypes for all the studied characters. PCV was higher than GCV for all the studied characters. The maximum GCV and PCV were observed for viz., seed yield per plant followed by biological yield per plant, number of capsules per plant, test weight and plant height. Higher estimates (h2b) >80% were observed for all the characters except harvest index, branches per plant, number of seed per capsule and biological yield per plant. High heritability coupled with high genetic advance observed for test weight, seed yield per plant and plant height indicating, these characters could be prominently governed by additive gene action. So the selection and improvement of these traits could be more effective and will help in improving the seed yield in linseed.
