“…The preponderance of nonadditive gene action for various yield and yield attributing traits was probably due to overdominance of genes and such gene action is very useful for the exploitation of heterosis in F1 hybrids. The possibilities for commercial exploitation of heterosis for yield attributes has also been reported by Jasim and Esho [17] in summer squash; Ashwini, B [20] in bitter gourd. However, the differences in the results might have due to the differences in the genetic material studied.…”

“…The role of additive and dominant genes in the inheritance various traits in bitter gourd was observed by various researchers viz., Bhatt et al [16] for various yield and yield attributes. Jasim and Esho [17] reported that additive variance was responsible for vine length whereas, non-additive for yield in summer squash. Similar results were observed by Talukder et al [18] in bitter gourd.…”

Thirty crosses developed through Line x Tester mating design along with their parents were evaluated for combining ability, heterosis and gene action for yield and its attributes in bitter gourd. The experimental material was evaluated in RCBD design with three replications at three different locations viz., Vegetable Experimental Farm, Division of Vegetable Science, SKUAST-Kashmir, Shalimar Srinagar (E1); Faculty of Agriculture, Wadura, Sopore (E2) and KVK Malangpora, Pulwama (E3). The mean squares due to parents vs crosses were significant for all the traits, which indicated the possibility of sufficient amount of heterosis exploitation for these traits. The \(\sigma\)2sca was found to be more than \(\sigma\)2gca for all the traits under study which indicated the preponderance of non-additive gene action for the traits. Both the variances (\(\sigma\)2gca and \(\sigma\)2sca ) were significant for most of the traits which reflects the importance of both additive and non-additive gene effects in the inheritance of these traits. The lines viz: NDBG-4, NDBG-1, NDBG-5, Pant Karela-1 and NDBG-7 were found to be good general combiners for most the economic traits. The extent of heterosis exhibited by crosses were estimated over standard parent (Arka Harit). The crosses viz: Pant Karela-1 × Arka Harit, NDBG-4 × Arka Harit, NDBG-1 × Arka Harit, NDBG-7 × Jounpuri, NDBG-5 × Jounpuri, NDBG-5 × Local bitter gourd, Pant Karela-1 × Jounpuri, NDBG-4 × Local bitter gourd and NDBG-4 × Local bitter gourd showed high standard heterosis for yield and yield attributes. These crosses can be exploited as desirable hybrids for yield.

“…Devi et al (2017a) found both additive and non-additive gene action in snake gourd. Jasim and Esho (2021) reported that additive variance was responsible for vine length whereas, non-additive for yield in summer squash. Similar results were also found in eggplant (Devmore et al, 2016), in bitter gourd (Talukder et al, 2018), in cucumber (Golabadi et al, 2017), and in bottle gourd Quamruzzaman et al (2020) found non-additive gene effects for first female flowering node as well as female flower number per stem, branches per plant in ridge gourd.…”

Combining ability analysis provides useful information for the selection of parents, also information regarding the nature and magnitude of involved gene actions. Crops improvement involves strategies for enhancing yield potentiality and quality components. Targeting the improvement of respective characters in bitter gourd, combining ability and genetic parameters for 19 characters were estimated from a 6×6 full diallel analysis technique. The results revealed that the variances due to general combining ability (GCA) and specific combining ability (SCA) were highly significant for most of the important characters. It indicated the importance of both additive and non-additive gene actions. GCA variances were higher in magnitude than SCA variances for all the characters studied indicating the predominance of the additive gene effects in their inheritance. The parent P2 (BG 009) appeared as the best general combiner for earliness; P1 (BG 006) for number of fruits, average single fruit weight and fruit yield; P4 (BG 027) for node number of first female flower and days to seed fruit maturity; P3 (BG 011) for fruit length and thickness of the fruit flesh; P5 (BG 033) for 100-seed weight; and P6 for number of nodes per main vine. The SCA effect as well as reciprocal effect was also significant for most of the important characters in different crosses.

Summer squash is an important member of the family Cucurbitaceae. It is one of the most popular vegetable crops cultivated in Egypt. Increasing yield and improving fruits quality are the targets for growers. Therefore, this study aimed to evaluate the extent of genetic variations, heritability, as well as expected genetic advance for growth and yield related traits in four genotypes of summer squash subjected to three doses of ultraviolet irradiation. Data were subjected to the analysis of variance for the important components of yield and agronomic traits. The results showed relatively small differences between phenotypic and genotypic variance for the number of leaves per plant, chlorophyll concentrations in leaves, and fruits. Larger magnitude of difference was obtained between phenotypic and genotypic coefficient of variations in the expression of leaf area, female flowers, male flowers developed per plant, and carotenoids concentration in fruits, indicating that environmental factors played predominance role in the expression of these traits. Moderate heritability value was obtained for fruits weight per plant coupled with high genetic advance as a percentage of mean. Therefore, selection based on the phenotypes will improve the mean performance of fruits weight per plant in the selected progenies.
