“…Roy et al (2018) and Nascimento et al (2014) revealed that non-additive gene action was more prominent in the inheritance of the studied traits viz., pericarp thickness, fruit yield, days to fruiting and TSS with exception to some characters such as fruit length, fruit diameter and fruit weight which were controlled by additive gene effects. Janaki et al (2017) reported a significant role of non-additive gene action in the inheritance of traits like fruit yield per plant, plant spread, days to 50% flowering, number of fruits per plant etc. Meanwhile, Adday et al (2016) reported that additive gene effects played a more important role than non-additive effects in the inheritance of all traits except the number of branches per plant.…”

Genetically diverse bell pepper cultivars and their 30 F 1 hybrids were developed by means of diallel mating system including reciprocals. Variance analysis illustrated considerable disparity among newly developed bacterial wilt resistant hybrid lines for all the studied traits. General Combining ability (gca) effects were more pronounced than specific combining ability effects (sca). The gca effects were high with parents DPBWRC-6-1, EC-464107, EC-464115 and DPBWRC-39 for fruit yield and yield-enhancing traits. Further, reciprocal effects influenced all parameters except fruit width, TSS and lobes per fruit. Among the additive and non-additive genetic variance, the latter had a more significant influence on the inheritance of all studied characters except for fruit width and pericarp thickness. Based on sca analysis, three cross-combinations viz., DPBWRC-29×EC-464107, DPBWRC-39× DPBWRC-1 and EC-464115 × DPBWRC-29 were found to be good specific combiners for the majority of traits and can further be utilized to isolate superior segregates or released as hybrids.

“…While, the medium GAM value was found in the characters of plant height, some seed pearls and color of the rice. Estimation of heritability followed by genetic progress is more useful than heritability alone in predicting the effects produced for the best selection (Pandey et al, 2009;Johnson et al, 1955in Janaki et al, 2017. High GAM values indicate that genetic factors strongly influence these characters.…”

A better understanding of variability in plant populations is crucial for crop improvement which plant breeders can use through selection. This study aimed to determine selection criteria for the sixth generation of black rice through genetic variability, heritability value and genetic advance. This research was conducted from March to July 2018 at Pakahan Village, Jogonalan Sub-district, Klaten Regency, Central Java, using a Randomized Complete Block Design (RCBD). The variables observed were plant height, total number of tillers and productive tillers, panicle length, number of seeds per panicle, panicle intensity index, weight per panicle, 1,000 seed weight, seed weight per plant, flowering age, harvest age, plot yield, yield per hectare, rice color and total anthocyanin content. Variance analysis showed that there was a very significant difference (p <0.01) among the genotypes tested for all observed characters indicating variability. In this study, the phenotypic coefficient of variance (PCV) values was relatively higher than the genotypic coefficient of variance (GCV) for all traits. However, GCV values were close to PCV values in some characters such as plant height, flowering age, harvest age, rice color and anthocyanin content which showed a high contribution of genotypic effects to the phenotypic expression of these characters. The high heritability and high average value of genetic advance were indicated in the parameters of plant height, flowering age, harvest age, rice color and anthocyanin content. The characters of plant height, flowering age, harvest age, rice color and anthocyanin content can be used as sixth-generation black rice selection criteria.
