“…High PCV and GCV values exhibited for number of branches per plant, number of capsules per plant, yield per plant, palmitic acid and linoleic acid indicating wide range of variability with substantial environmental influence on the expression of these traits and provide better opportunity for improvement of these traits through selection. Similar results of high PCV and GCV values for above said traits were also reported by Bibi et al (2013) [3] , Ranjana et al (2018) [14] , Vipin et al (2019) [18] and Ankit et al (2019) [2] . Coefficients of variation studies indicated that the estimates of PCV were slightly higher than the corresponding GCV estimates for all the traits studied indicating that the characters were less influenced by the environment.…”

“…Panse and Shukhatme (1978) [12] have expressed that if a character is governed by additive gene action, directional phenotypic selection of these traits could be more effective for desired genetic improvement, heritability and genetic advance both would be high. The findings of higher heritability and expected genetic advance are in line with the findings of Vishnuvardhan and Rao (2012) [19] , Kumar et al (2012) [10] , Pali and Mehta (2013) [11] , Amith et al (2017) [1] , Frank et al (2017) [7] and Ranjana et al (2018) [14] . High heritability is suggestive of the scope for higher genetic gain in seed yield through selection (Todorovic et al, 2011) [16] .…”

One hundred linseed (Linum usitatissimum L.) genotypes and four checks were evaluated during rabi, 2017-18 for fifteen traits to examine the nature and magnitude of variability, heritability (h2=broad sense) and genetic advance. Analysis of variance revealed that the differences among genotypes were significant for all the characters studied. Knowledge of selection effect on positive or negative changes of a character under improvement is of paramount importance for the success of any plant breeding programme and helps the selection of desirable breeding methods. Heritability and genetic advance are important selection parameters and selection success is a reflectance of selection response. High PCV and GCV values exhibited for number of branches per plant, number of capsules per plant, yield per plant, palmitic acid and linoleic acid indicating wide range of variability with substantial environmental influence on the expression of these traits and provide better opportunity for improvement of these traits through selection. Small differences between GCV and PCV were recorded for all the characters studied which indicated less influence of environment on these characters. High heritability coupled with high Genetic advance as per cent of Mean (GAM >20%) observed for plant height, technical plant height, number of branches per plant, number of capsules per plant, yield per plant, palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid indicated that these characters are highly heritable.

“…The authors believe that when creating high-yielding flax varieties, the selection strategy should focus on lateral shoots and stems (Paul & Kumar, 2019). Thus, the authors concluded that stems, lateral shoots, bolls, plant height and other traits can be used as a breeding index to improve seed yield (Patial et al, 2018). Our data established that the main feature of the habit of the plant, which strongly affects the number of bolls, is the number of lateral shoots.…”

The studies were carried out at the Institute of Oilseed Crops of the National Academy of Agrarian Sciences of Ukraine in 2019/2020. The material of the study was interspecific hybrids of the second generation obtained in the system of dialel crosses with the participation of two wild annual homostylic species L. angustifolium and L. hispanicum with n = 15 and three accessions of cultivated flax: L 5 (Czech Republic), L 6 (India), M 32/2 (Ukraine). Correlation analysis of habitus traits of a flax plant with the number of bolls was carried out. As a result of studies between the height of the plant and the number of stems on the plant, there is no relationship; between the height of the plant with the number of lateral shoots and the number of bolls, weak and medium correlations, and sometimes their absence, were established (r = +0.218…+0.559; r = +0.253…+0.698, respectively). Medium and strong correlations were found between the number of stems on a plant with the number of side shoots and the number of bolls (r = +0.334…+0.892; r = +0.482…+0.818). Exceptionally strong and stable over the years correlations were observed between the number of lateral shoots on the plant and the number of bolls (r = +0.700…+0.922). The main trait of the habitus of a flax plant, which significantly affects the number of bolls on them, is the number of lateral shoots. This trait can be used as a reliable criterion for selecting plants for breeding for high seed productivity.

“…This showed that the selection for biological yield and harvest index would have a direct positive effect in the improvement of grain yield and are the most important determinants of yield also suggested by Tadesse et al (2009). As suggested earlier, studies by Sharma et al (2016) and Patial et al (2018) have indicated the importance of biological yield for improvement of seed yield. However, positive correlation of the number of primary branches and the number of secondary branches with seed yield was due to indirect effect via biological yield in EI (0.20938; 0.10037, respectively) and via harvest index in EII (0.07286; 0.05321, respectively).…”

The present experiment was conducted to determine the important yield components and their association with one another and with yield. The experiment was laid out under two production systems over four different locations in the mid-hills of the North-western Himalayas. Correlation studies indicated a strong positive correlation for seed yield with harvest index (EI 0.668**; EII 0.472**) and biological yield (EI 0.362; EII 0.532) in both the production systems. Whereas, a non-significant positive correlation was observed for the number of primary branches (EI 0.103; EII 0.122) and the number of secondary branches (EI 0.033; EII 0.160) in both production systems. Whereas, among other traits highly significant correlation was observed for days to 50% flowering with days to 75% maturity in both production systems (EI 0.837**; EII 0.781**) followed by plant height (EI-0.626 ** ; EII-0.562 ** ) and technical plant height (EI 0.617 ** ; EII 0.598 ** ). Path coefficient analysis indicated that only biological yield (EI 0.70348; EII 0.60597) and harvest index (EI 0.90210; EII 0.53283) showed a highly significant direct effect with seed yield in both production systems. This showed that selection for biological yield and harvest index would have a direct positive effect in the improvement of grain yield and are the most important determinants of yield in linseed. However, traits such as number of primary branches, number of secondary branches and 1000 seed weight should also be given significant importance since these traits also showed a positive correlation with seed yield but with indirect effects via biological yield and harvest index in EI and EII, respectively.
