Potential of parents and hybrids experimental of the yellow melon

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.

Heterosis and Combining Ability for Fruit Yield, Sweetness, β-Carotene, Ascorbic Acid, Firmness and Fusarium Wilt Resistance in Muskmelon (Cucumis melo L.) Involving Genetic Male Sterile Lines

“…Therefore, for these traits, the contribution of dominance variance was higher than the additive genetic variance (Table 2). These findings were consistent with other studies [46][47][48][49]. However, additive gene and both additive and dominant gene actions have also been reported to be predominant in the genetic control of these traits [15,50,51,57].…”

“…The significance of both GCA and SCA variances indicated the role of both additive and nonadditive gene effects in governing these traits. Similar gene actions in controlling the fruit yield, number of fruits per vine and average fruit weight have been reported in previous studies in muskmelon [43][44][45][46]. However, Saha et al [47] and Badami et al [48] reported the dominant gene action to be responsible for controlling the yield-related traits, such as the fruit weight.…”

Diallel Analysis for Yield and Quality Characteristics in Melon

“…Differences of genotypes are associated with variability that exists between materials [11]. Response of additive effects (GCA) and non-additive effects (SCA) is involved in genetic control of trait [12]. Results of general and specific combining ability provide relevant information on parents and progeny to continue advancing in breeding program.…”

Produção e Qualidade de Melões Sob Diferentes Arranjos do Sistema de Irrigação e Coberturas do Solo

“…As cultivares de melão de maior expressão nacional são do tipo Pele de Sapo, Amarelo, Cantaloupe e Gália, com tendência crescente a exploração de híbridos pelo seu potencial produtivo, especialmente quando irrigado (Lima, 2015;Cavalcante Neto et al, 2020). Irrigação esta que é promovida predominantemente pelo sistema de gotejamento, por evitar molhar a parte aérea da planta, permitir maior controle na quimigação e maior eficiência de uso da água.…”
