| Popis: | The recent experiment with the title “Genetic variability in bold seeded linseed (Linum usitatissimum L.) was conducted in “Research cum instructional farm, Department of Genetics and Plant Breeding, College of Agriculture, IGKV, Raipur, C.G.” during rabi season 2021-2022, we used total 40 bold seeded (> 6.5 gm of 1000 seed weight) linseed genotypes including 5 checks (RLC-133, RLC-138, RLC-143, RLC-148 & RLC- 153), we used Randomized complete block design with three replications for sowing the seed in field and observations were recorded for different agro morphological traits, listed on linseed descriptors Kanpur (2010) are “days to commencement of flowering, plant height(cm), days to 50 % flowering, days to maturity, number of primary branches per plant, number of secondary branches per plant, total number of branches per plant, number of capsules per plant, number of seeds per plant, 1000 seed weight (g), oil content (%), harvest index (%), and seed yield per plant (g).” All the 40 bold seeded linseed genotypes were gone through D2 analysis for diversity analysis here cluster analysis distributes all the 40 genotypes into 5 clusters. Maximum number of genotypes (31) were grouped in cluster I. According to “intra-cluster distance, the most diverse clusters among all clusters were cluster II and the highest inter cluster D2 values were noted between cluster V and I (1001.96) followed by cluster V and III (852.10), cluster V and IV (607.26), cluster III and II (365.71) and cluster II and I (357.90). In hybridization program highly diverse genotypes are used.” |
