“…Analysis of variance (ANOVA) for most of studied traits reflected that genotypic variances were highly significant within as well as across the environment, revealing their higher level of heritability. The findings of this study are in line with previous studies [38,41,42] stating that days to maturity, pods per plant, number of seeds per plant, and 100 seeds weight are less influenced by environmental forces and are highly heritable traits under multi-year/locations.…”

Plant landraces represent a repository of a gene pool, local adaptation of their domestic species, and thereby are considered a great source of genetic variations. Such genetic variation can be helpful to mitigate the current and future food challenges. A total of 183 common bean accessions including three commercial varieties collected from 19 Turkish provinces were grown to record their morpho-agronomic variations and to evaluate the best performing accessions under multi-environmental conditions. Plant height, days to maturity, pods weight, seed length, and 100-seed weight were used to evaluate the best performing accessions under different environmental conditions. A wide range of variations for traits like days to maturity (99-161), plant height (21-168.7 cm), seed length (7.41-16.4 mm), seeds per plant (17.8-254.4), and 100-seeds weight (24.97-73.8 g) were observed and can be useful for breeding purposes. The analytic results derived from the first three eigenvectors suggested that plant height, plant weight, 100-seed weight, and days to flowering were biologically significant bean traits. Seed yield per plant was positively and significantly correlated with plant weight and pods weight. Genotype × environment biplot discriminated the studied common bean accessions based on their plant height and growth habit. Plant height, days to maturity, seed width, and first pod height were found highly heritable traits and were least affected by environmental forces. Among 19 provinces, accessions of Bilecik showed maximum pods per plant, seed yield per plant and 100-seed weight, while Erzincan and Sivas provinces reflected the prevalence of bushy and early maturing accessions. Information provided herein comprehensively explored the occurrence of

“…Consequently improvement of these characters can be achieved through careful selection. The low heritability and low genetic advance recorded for plant height and number of seeds suggest that these characters governed by non-additive gene action [30]. The correlation coefficients among characters were determined at the phenotypic and genotypic levels.…”

The need to find suitable alternative to fossil fuel necessitated the search for non-food oil crops like physic nut (Jatropha curcas L.). Improvement of the crop requires adequate knowledge of extent of genetic variability present. Therefore, a study was carried out to determine genetic variability and character association among forty local and exotic accessions of physic nut. The accessions were evaluated in two years in randomized complete block design with three replications. Results indicated highly significant variation among the accessions for all characters studied except plant height and number of seeds per fruit. High estimates of heritability were observed in number of leaves (84.10%) and seed oil (94.97%) while heritability was low in number of seeds (11.30%) and plant height (13.36%), other characters had moderate heritability. High heritability estimates were accompanied by relatively low genetic advance in all the traits except kernel oil, an indication that the character has high selection value with less environmental influence. Correlation analysis showed that tall plants produced bigger seeds because of the positive association between plant height and seed weight. Therefore, seed weight can be used as selection index.

“…Genotype named Varun was treated with different concentration of chemical mutagen i.e., gamma rays and observed maximum heritability for 100-seed weight, plant height and length of pod (More et al, 2016). At two different locations the heritability varies from 38.9% for primary branch to 86.9% for harvest index at one location & from 30.5% for days to emergence to 95.86% at another location for nine genotypes (Wondimu et al, 2017). Maximum heritability coupled with high genetic advance for pod yield, pod yield per plot and plant height was recorded which indicate presence of additive gene action (Gudadinni et al, 2017).…”

“…of leaves /plants, pod weight & pod yield/plant, maximum variability was found in eighteen different genotypes (Lyngdoh et al, 2017). In nine French bean (Phaseolus vulgaris L.) genotypes grown at two different locations highest variability for primary branches, grain yield, hundred seed weight & number of pods /plants was recorded (Wondimu et al, 2017). In 15 genotypes of Pea, significant differences among all genotypes were observed regarding growth yield and yield attributes parameters.…”

“…Maximum genetic advance for plant height and seed yield per plant in seventy-five genotypes was recorded (Panchbhaiya et al, 2017). At two different locations the percentage of genetic advance varied from 6.8% (Days to maturity) to 65.47% (stand out at harvest) in nine different genotypes (Wondimu et al, 2017). Highest genetic advance were recorded for yield/plant (72.78%) & pod flesh thickness (0.11%) in seventy-five genotypes (Jhanavi et al, 2018).…”
