“…Fruit yield per plant has also shown negatively and insignificantly correlated with diameter of fruit (-0.119). The findings of positive correlation are also confirmatory with Patel and Patel (2014), Yatung et al (2014) and Dolkar et al (2015), Patel et al (2015), Sharma andSridevi (2016), andMamatha et al (2016). In contrast, fruit yield showed positive and nonsignificant correlation with days to 1 st flowering (0.154), number of branches per plant (0.149), number of seeds per plant (0.048) and weight of 1000 seeds (0.119).…”

“…The path coefficient analysis (Table 4) showed that, weight of individual fruit (0.293) had highest positive direct effects on fruit yield per plant followed by plant height (0.205), number of branches per plant (0.186), length of fruit (0.164), number of fruits per plant (0.132) and diameter of fruit (0.078) which is in agreement with Yatung et al, (2014), Pandit and Adhikary (2014), Patel et al, (2015), Mamatha et al, (2016) and Sharma and Sridevi (2016). On the other hand, the direct negative effects were recorded for days to 1 st flowering (-0.148), number of seeds per fruit (-0.133) and weight of thousand seeds (-0.211) on fruit yield per plant.…”

Genetic variability, heritability, genetic advance, correlation coefficient analysis, path coefficient analysis and genetic divergence between yield and its contributing traits were estimated using fifteen (15) different chilli genotypes in northern region of Bangladesh. The aim of this study is to screen out suitable parents for next hybridization program. The phenotypic coefficient of variations was found slightly higher than the genotypic coefficient of variations for all characters studied, indicating that the apparent variation is not only genetic but also influenced by the growing environment in the expression of the traits. High genotypic and phenotypic coefficient of variation was observed in length of fruit (27.27% and 27.81%). High heritability coupled with high genetic advance in percent of mean in fruit yield per plant (71.23 and 39.38), number of fruits per plant (71.26 and 31.18), weight of individual fruit (88.52 and 43.80), length of fruit (96.13 and 70.59) and diameter of fruit (79.58 and 35.79) suggested that these characters would be considered for varietal selection. The correlation studies revealed that fruit yield per plant showed significant positive correlation with plant height (0.369), number of fruits per plant (0.587), weight of individual fruit (0.634) and length of fruit (0.450) which can be considered for selection of a good variety. Path analysis revealed weight of individual fruit (0.293), plant height (0.205), number of branches per plant (0.186), length of fruit (0.164), number of fruits per plant (0.132) and diameter of fruit (0.078) had direct positive effect on yield per plant, indicating these traits are the main contributors to fruit yield per plant. The divergence value for cluster analysis showed the highest inter-cluster distance between clusters II and IV which indicates that these genotypes may provide high heterosis in hybridization and expected to show wide variability in genetic architecture.

“…Characterization of chili genotypes based on their diverse phenotypic and genotypic selection are mandatory and help to increase chili production and mitigate the problem which are related to different stresses. Breeding programs for crop improvement are enabled by the availability and detailed characterization of genetically diverse germplasm (Usman et al, 2014;Patel et al, 2015;Ridzuan et al, 2019). Heritability is linked with some important traits and provides opportunities to improve new desirable plants (Lahbib et al, 2013;Patel et al, 2015).…”

A better understanding of the various desirable characteristics present in chili (Capsicum annuum L.) genotypes has aided in developing more effective selection methods for crop improvement. Identifying genetically superior parents is critical in selecting the best parents and inbred lines for breeding purposes. This study was conducted over two planting seasons in glasshouse using morpho-physiological parameters to evaluate the heritability variation of selected chili genotypes based on their genetic diversity for future breeding program. Significant variances were observed in all the studied parameters across the chili pepper accessions with an inclusive range of diversity. The highest genotypic coefficient of variation (≥ 20%) was observed for all physiological and yield characteristics. While the highest phenotypic coefficient of variation (≥ 20%) was seen for all examined characteristics. All studied parameter had high broad sense heritability (˃ 55%) except total number of branches per plant (47.9%) while the moderate to high genetic advance were observer for all studied traits demonstrating that the extents of heritability and variability are due to their genetic makeup and environment had little influence on these characters. The evaluated genotypes were grouped into seven clusters based on the cluster analysis and Group I recorded highest yield with eight genotypes while Groups III, IV, V, VI, and VII recorded one each. Plant height and total branch number showed a highly significant positive correlation with the number of fruits per plant and yield per plant. Similarly, the number of fruits per plant had a highly significant positive correlation with fruit yield per plant. The study revealed that genetic variability might be usefully exploited through selection for further breeding purposes to increase yield and production.

“…Therefore, the selection of genotypes favorable to this association is a field of research to be explored in order to consolidate the inoculation technology with diazotrophic PGPB as a viable alternative to synthetic nitrogen fertilizers for maize production. In this context, diallel analysis is an essential tool to identify superior parents for hybrid or cultivar development related to several traits of interest (Patel et al, 1998). Thus, the objectives of this work were to determine, using partial diallel crossing, the general and specific combining ability of twelve elite inbred lines of maize with three tester lines and to verify their possible interactions with A. brasilense strain Ab-V5.…”

One of the most prominent strategies to increase maize grain yield with a higher benefit/cost ratio and a lower environmental impact is the inoculation of plant growth-promoting bacteria. Among other factors, the success of the interaction plant-microorganism depends on genetic traits, therefore, selection of plant genotypes compatible with this association is extremely important to the viability of this technology. This article presents an innovative study that investigates the interactions between Azospirillum brasilense Ab-V5 and 27 genotypes of maize, including 24 experimental hybrids from a partial diallel (denotated H ij as a result of the crosses among the parental inbred lines L i and the tester breeding lines T j ), the variety ST0509 from UEL and the commercial hybrids DKB390 and DKB390H from Monsanto. The plots consisted of treatments with or without inoculation in three replicates and the 27 maize genotypes were randomly distributed in the sub-plots. The inbred lines L 2 , L 3 , L 6 , L 11 , T 2 and T 3 present the highest general combining ability, producing the best hybrid combinations. The additive effects of genes are more important than the non-additive effects for all traits evaluated. The most promising experimental hybrids are H 2 3', H 3 2' , H 11 2', H 11 3' and H 12 3' . Significant effect for inoculum was not verified when performed at the seedling stage in the experimental conditions of this study.
