In different crop plants, combining ability and heterosis are used as important diagnostic tools for assessing the performance of parental genotypes and their hybrids. This research aimed to evaluate heterotic and combining ability effects in the diallel crosses of melon (Cucumis melo L.) for yield- and quality-related traits. Seven melon (C. melo L.) genotypes were grown and crossed in a complete diallel fashion to produce F1 hybrids. During the 2019 crop season, 49 melon genotypes (7 parents + 42 F1 hybrids) were grown in a randomized complete block design with three replications. Observations were made for seven characters. Analysis of variance revealed significant (P ≤ 0.01) differences among the melon genotypes for harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit diameter and merely significant differences (P ≤ 0.05) for fruit weight. Combining ability analysis revealed that mean squares due to general combining ability (GCA) were significant for fruit diameter but were nonsignificant for all other traits. However, mean squares due to specific combining ability (SCA) were significant for all traits. The parental genotypes PK-165, PK-464, and PK-669 exhibited the highest and desirable GCA effects for yield and quality traits. Hence, these genotypes could be used to generate high-yielding hybrid/open-pollinated cultivars. GCA:SCA ratios further revealed that the traits of harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit weight were controlled by dominant gene action, whereas fruit diameter was managed by additive and dominant genes. The majority of the traits were controlled by nonadditive gene action, verifying that the said breeding material could be efficiently used for the production of hybrid cultivars on the basis of heterotic effects.

Information on the inheritance of yield and quality traits is important for the selection of parents and breeding approaches to be adopted for the improvement of strawberry. The present study aimed to estimate the combining ability and gene effects for plant yield, fruits number/plant, fruit weight, pulp firmness and sugar content of strawberries in order to identify the best genitors and promising crosses, in 30 hybrids of six parents. The additive and non-additive gene action as well as the maternal effects was involved in the inheritance of the studied traits. For all traits, especially for fruit weight and plant yield, the additive gene action was more important than the non-additive one. The parents ‘A1’ and ‘Alba’ showed a higher concentration of favourable alleles for plant yield and fruits number, and they will allow the increase of plant yield when used as a donor of pollen and the increase of fruit number when used as a recipient of pollen. The variety ‘Marmolada’ was a good general combiner for sugar content, pulp firmness and fruit weight, especially when used as a female genitor. These parents could be used in hybridization in order to accelerate the genetic improvement of some yield and quality traits in strawberries. The cross ‘Mira’ × ‘Onda’ expressed desirable specific combining ability effects for yield traits and can be successfully use in strawberries breeding programs. In the case of ‘Alba’ × ‘Clery’ there is a high probability to select progenies with valuable yield traits associated with sweet fruits.

An investigation was carried out to assess the combining ability and nature of gene action in baby corn (Zea mays L.) genotypes, by making crosses of eight inbred lines namely, HKI 3209, SML 1, EC 595979, CM 128, VQL 1, G 18 seq C5 F 76-2-2-1-1-2-BBB, HKI 209, in diallel mating design (without reciprocal crosses) by following Griffing Model–I and Method–II during rabi season 2013-14 at the experimental farm of BAC, Sabour, Bhagalpur (Bihar). The crosses were evaluated in a randomized complete block design (RCBD) to assess the combining ability and nature of gene action. Based on general combining ability, parents CM 128 and VQL 1 were best parent forbreeding programme for yield and quality improvement. The specific combining ability also indicates that hybrid CM128 x VQL1 was best specific combiner for baby corn yield (4.11q/ha), fodder yield (50.91q/ha) as well as for better quality. The crosses CM 128 x HKI 209 recorded the high mean (7.35%) and SCA effects (2.57 ºBrix) for quality traits. The gene action analysis also revealed preponderance of non-additive gene action for yield and its contributing characters.
