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 intraspecific hybridization programme among Cucumis species involving eight genetically diverse parents of C. melo L. varietal group viz., IC-0599709, Punjab Sunehri, Pusa Madhuras, Kashi Madhu (C. melo L.), AHK-119 (C. melo var. callosus), AHLM-2 (C. melo var. utilissimus), AHS-82 (C. melo var. momordica) and Arya-1 (C. melo var. chate) were undertaken. Among the dessertic F1 hybrids, IC-0599709 × Punjab Sunehri resulted best with respect to first fruit harvest (73.33 days), fruit weight (938.00 g), fruit diameter (11.90 cm), flesh thickness (3.07 cm), total soluble solids (9.73%) and flesh colour (salmon orange). F2 population of AHK-119 × Kashi Madhu produced maximum number of marketable fruits per plant (11.2) weighing 350.00 g in 86.1 days. It was also found to be tolerant to high temperature. The F2 population of AHK-119 × Kashi Madhu were found to be tolerant to high temperature. The existing variability among the parents, intra-specific crosses and segregating generations for fruit (size, shape, colour), yield and quality parameters could be exploited to develop new segregants with desirable traits.

ABSTRACT: Melon or muskmelon (Cucumis melo L.) is of considerable economic importance in Brazil. Nearly all the cultivars currently grown are hybrids. Heterosis has been used to advantage in the melon plant, and the use of uniform hybrids is one of the reasons for successful cultivation. The aim of the present study was to evaluate the agronomic potential of yellow melon lines and hybrids. An experiment was conducted in randomized blocks with three replications to evaluate 24 hybrids generated by crosses among three elite lines used as female parents (AF-01, AF-02, and AF-03) and eight lines used as male parents (LAM-01, LAM-02, LAM-03, LAM-04, LAM-05, LAM-06, LAM-07, and LAM-08). Yield and fruit quality traits were evaluated. Partial diallel analysis was carried out to estimate general combining ability and specific combining ability. Additive and non-additive effects were observed for the yield, mean fruit weight, and pulp thickness traits. The lines AF-02, LAM-02, and LAM-03 are the most promising as parents as they more frequently have favorable alleles. The most prominent hybrids in diallel analysis were AF-02 x LAM-02, AF-02 x LAM-03, AF-02 x LAM-04, and AF-03 x LAM-06.

The creole melon cantaloupe is a horticultural species, whose fruits are used for human nutrition. However, no research has been reported on their genetic variability for starting breeding processes. The objective of this study was to take advantage of the variability of creole melons for genetic improvement. 20 creole melon half-sib families were selected and evaluated for production characteristics and fruit quality in order to obtain improved populations. The study was carried out in Palenque canton, Ecuador. Seeds from 20 half-sib families were used, arranged in a randomized complete block design with three replications. The differences between the families were significant for all the studied characteristics. Family 93 presented higher averages for fruit weight, fruit diameter and production (per hectare), and family 196 did so for soluble solids. The phenotypic correlations were positive and significant between the fruit weight and fruit diameter, fruit length, pulp thickness, fruit cavity, soluble solids and production. The coefficients of genetic variation, in general, were lower than the coefficients of environmental variation. The estimates of heritability broadly had a moderate magnitude (30-60%) for the 10 evaluated characteristics, and the magnitude of the expected genetic progress was low (<10%) for the fruit weight, production, and soluble solids, so the selection for high production should focus on fruit weight and soluble solids.

The objective of the experiment was to screen Cucumis melo L. inbred lines for high potential general combining ability and potential hybrids combinations for F1 hybridization. The experiment was conducted as a randomized complete block design (RCBD) with 29 treatments [21 hybrid combinations, control (TL3 hybrid) and seven Cucumis melo L. inbred lines I6], each with three replicates. Estimating the specific combining ability (SCA) of Cucumis melo L. inbred lines for breeding of F1 hybrid cultivars was carried out at the Research and Development Center for Hi-tech Agriculture in Ho Chi Minh City. Based on the specific combining ability of yield trait and total soluble solids (Brix) content of 21 hybrid lines from seven inbred lines following diallel method (Griffing 4 model), four potential hybrid lines (H41.6 x H58.6, H53.6 x H77.6, H32.6 x H41.6 and H53.6 x H58.6) yielded 10% higher than the control variety and gave fruits of oval shape, even fruit-net and low diseases infection.
