“…High heritability estimates for plant height was also reported by Tomar et al (2012), Godbharle et al (2010) and Bhagasara et al (2017) which is in accordance with the present findings. Like the present study, high heritability estimates for hundred seed weight was also reported by Bhagasara et al (2017).…”

The present study consists of 14 sorghum genotypes evaluated at Bako, Jimma and Mechara research centers to study genetic variability and interrelationships of traits with grain yield. The experiment was conducted by using randomized complete block design (RCBD) with three replications during 2014 and 2015 main rainy season. Data on important agronomic traits were collected. The combined analysis of variance (ANOVA) across years and locations showed highly significant differences among genotypes for all traits, indicating the presence of sufficient variability among the genotypes. Environmental coefficients of variation (ECV), genotypic coefficients of variation (GCV) and Phenotypic coefficient of variation (PCV) ranges of the study are days to 50% maturity (DM, 0.49) to number of seeds per panicle (NSPP, 6.11); DM (0.31) to PAS (16.99) and DM (1.12) to GY (20.86) in the same order. High h 2 BS values were observed in hundred seed weight (HSW, 76%), DS (70%), plant height (PH, 65%) and PAS (63). High value of genetic advance as a percentage of mean (GA% µ) was recorded by PAS (27.42%), PH (26.29%) and DS (20.65%) and moderate amount of GA%µ was recorded by HSW (11.78%) and HW (11.08%). High h 2 BS coupled with high to moderate GA%µ was reported for PH (65 and 26.29%); HSW (76 and 11.78%); PAS (63 and 27.42%) and DS (70 and 20.65%) indicating PH and HSW are controlled by additive gene action. GY had strong positive genotypic association with HW (0.99) followed by NSPP (0.96). These results suggested that any positive increase in such traits will increase the grain yield. The genotypic path analysis also showed that head weight per plot (HW, 1.96) and PH (0.55), had high and very high positive direct effect, respectively on GY indicating that these traits are the most important yield component traits. Hence, due consideration should be given to these traits while selecting promising lines.

“…Similar findings were achieved in an investigation on yield and related traits on sorghum germplasm by Bhagasara et al. (2017), and our results are consistent with the recent findings regarding salinity tolerance in wheat cultivars (Fellahi et al., 2019). The interaction plots showed significantly potential performances of tomato accessions under control and stressed conditions with variable response against saline environments and detected tolerant accessions at increased salt level.…”

Soil salinity, being world's gravest and increasing environmental threat, limits the growth and development in nearly all crop plants. The experiment was laid out to investigate the tomato local and exotic germplasm for morpho‐physiological and photosynthetic attributes under salinity stress (0 (control), 8 and 12 dS m−1). The phenotype data for morpho‐physiological traits were collected; meanwhile, photosynthetic pigments were analysed also at seedling stage. Analysis of variance, interaction plot, PCV and GCV revealed significantly greater diversity among all accessions for subjecting attributes. Strikingly, principle component analysis (PCA) biplot and cluster heatmap exposed potentially salt tolerant accessions (NAQEEB, BL1076, PBLA1401, 017859, TINY TIM, BL1174, BL1078, PBLA1932, TOMMY TOE, PAKIT and CLN2413) under the highest level of salinity for β‐carotene, lycopene contents, chlorophyll b, carotenoids, pheophytin (b) and total pheophytin. The overall performance of the above‐mentioned accessions was found significant and exhibits tolerant attitude under high salt levels. We suggest that these tolerant accessions might facilitate as a potential source for further breeding programme to improve the agronomically important traits by exploiting both conventional as well as molecular breeding efforts.

“…The phenotypic and genotypic phases can display dissimilarity amidst the natural population of cross-pollinated plants. In the proof of distinctiveness of the components with better responses to selection, phenotypic and genotypic coefficients of variations remained to be a supportive indication [63]. The categorized estimation values indicated (high (>20%), intermediate (10-20%), low (<10%)) as reported by Oladosu et al [27] for both PCV and GCV were adopted.…”

“…The trait selection was governed by the potential measure of variability presented by Shi et al [51]. The prerequisite in all breeding programs was the disparity in treatments, the objective of which was to improve the characters for better productivity [63]. To distinguish among progenies (treatments), characters with better variability had the potential of interest [51,66].…”

This research was conducted to study the performance of biparental dura × pisifera (D × P) progenies and their parental genetic origins on fruit set and yield components. Twenty-four D × P progenies developed from 10 genetic origins were used for this study. Analysis of variance showed that there was genetic variability based on the evaluation of individual progenies. Deli Ulu Remis × Nigeria of progeny ECPHP500 recorded the highest bunch number (22.91), and fresh fruit bunch (184.62 kg palm−1 year−1) and Deli Banting dura × AVROS pisifera (ECPHP550) had the highest average bunch weight (10.36 kg bunch−1 year−1). Progenies PK4674 (61.12%) and PK4465 (60.93%) had the highest fruit set, and the highest oil yield of 52.66 kg bunch−1 was noticed by progeny PK4674. Estimation of variance components, coefficients of variation, heritability, and genetic gain were calculated to establish the genetic variability. To validate the genetic disparity among the progenies, an unweighted pair-group procedure with arithmetic mean (UPGMA) and principal component was employed based on their quantitative traits. Through the UPGMA and principal component, the 24 progenies were clustered into 7 clusters, whereas cluster V had the highest fruit set (60.62%) and cluster IV had the highest oil yield (43.71 kg palm−1 year−1). For oil palm tissue culture and breeding programs, progeny PK4674 will be more useful for developing planting materials of high oil yielding with stable performance. However, we recommend that future studies incorporate molecular studies with conventional breeding.
