“…The high genetic mean advance was observed for height (H), followed by primary branches (PB), pursued by secondary branches (SB), further followed by number of seeds per capsules(NOSC), trailed by plant stand per plot (PSP), yield per hectare (YH) and number of capsules per plant (NOCP). Similar results for number of capsules per plant and yield were reported by Kumar et al (2012), for branches per plant, capsules per plant, yield per plant and seed weight were reported by Gupta and Godawat (1981) and also for number of primary branches portrayed by Naik and Satapathy (2002).Genetic advance as a percentage of mean was found to be highest for the number of capsules per plant (56.67%) followed by SYP (53.11%), BM (48.71%) and NSB (46.99%) was accounted by Hussain et al (2022).…”

The experiment was carried out for 20 genotypes were subjected to diversity analysis, cluster analysis, heritability, correlation and path analysis. High PCV and GCV for the secondary branches (SB), followed by plant stand per plot (PSP), further trialed by yield per hectare (YH) and trialed by number of capsules per plant was greater than > 20% .High broad sense heritability was found for days to 50% flowering (DTF), followed by height (H), pursued by number of capsules per plant (NOCP), (98.49%), tailed by secondary branches (95.54%) and further monitored by plant stand per plot (88.89) and ensued by yield per hectare (91.23). Also, high heritability is governed by additive gene action for these characters. Characters with moderate heritability with low genetic advance as percentage of mean are governed by non-additive gene action and direct selection may not be possible because most of the variation in attributes due to the environmental effects. The high genetic mean advance for height (H), followed by primary branches (PB), pursued by secondary branches (SB), further followed by number of seeds per capsules (NOSC), trailed by plant stand per plot (PSP), yield per hectare (YH) and number of capsules per plant (NOCP). In the present study, days to 50% flowering (DTF) were correlated, significantly to the days to 75% maturity (DTF) (0.7991, 0.5391) and secondary branches (SB) (0.4511, 0.4181) significantly. Also, days to 75% maturity (DTM) positively and significantly correlated to height (H), secondary branches, number of seeds per capsule (NOSC) and 1000-seed weight (SW). Similarly, number of capsules were positively and significantly correlated to primary branches (PB) (0.6960, 0.5854) and yield per hectare (YH) (0.4977, 0.4912). Also, days to 75% maturity (DTM) were negatively and significantly to number of capsules per plant (NOCP), primary branches (PB) and 1000 seed weight (SW). Number of capsules per plant (NOCP) negatively correlated to secondary branches (SB) and number of seeds per capsule (NOSC). It showed positive and significant direct effect for primary branches (PB) i.e., 0.5882, number of seeds per capsule (NOCP) i.e 0.4784 and plant stand per plot (PSP) 0.7529 and non-significantly positive for number of capsules per plant (NOCP), secondary branches (SB) and seed yield per hectare (YH). The genotypic correlations difference was higher than the corresponding phenotypic correlation for all traits, indicating that environment plays a small role in the expression of the traits, which suggests an inheritance between these traits at the genetic level. Cluster analysis displayed 10 clusters with diversity with 5 genotypes in cluster so they are related and four clusters have single genotype so they unrelated to any cluster.

Comprehensive information on genetic variability and selection parameters is very crucial to design breeding strategies. However, very limited information is available in Ethiopian linseed germplasm. Therefore, the present study was conducted to estimate genetic variability, broad sense heritability and genetic advance; and determine selection for 19 quantitative traits using 126 genotypes (120 Ethiopian linseed accessions and six released varieties). The analysis of variance showed highly significant (P < 0.01) differences for all of the traits demonstrating the presence of high genetic diversity among the studied linseed genotypes. Higher differences between PCV and GCV estimates were observed for seed yield per plant and biological yield per plant, signifying the importance of environmental factors influence. High heritability coupled with high genetic advance was observed for seed yield per plant and biological yield per plant, indicating that this high heritability is due to additive gene effects and therefore, selection can be effective for the improvement of linseed for these traits. In addition, moderate heritability coupled with moderate genetic advance was recorded for oil yield per hectare, number of capsules, number of secondary branches, days to maturity, seed yield per hectare and plant height. These results indicated the existence of intermediate expression in these traits for both additive and dominance gene effect. In the present study, high heritability coupled with high GAM was observed for seed yield per plant and biological yield per plant, indicating greater contribution of additive gene action for the expression of these traits; and therefore, improvement can be achieved through selection in these traits.
