“…In the present study, the estimates are close to those observed by Silva, Nunes, Costa, Aragão and Maia (2011) for Galia melon lines in different environments of northeastern Brazil. They are also within the range of values observed in some studies conducted in other countries (Randhawa & Singh, 1990;Feyzian, Dehghani, Rezai, & Javaran, 2009). It is noteworthy that the coefficient of genotype determination is inherent to population and environmental conditions, as is heritability.…”

“…However, the results obtained in this study show that the lines derived by the program exhibit potential for one environment per se, but not for the other. Nevertheless, it is worth noting that the genetic control of various traits related to melon yield and quality is due to the predominance of nonadditive gene effects (Feyzian et al, 2009). Thus, even when there is inconsistent performance in the two environments, it is possible that these lines may be used in the formation of hybrids to be recommended for both Mossoró and Baraúna.…”

ABSTRACT. The aims of this study were to i) identify the influence of the GxE interaction in the selection of inbred lines of melon, and ii) test the efficiency of different indexes in the selection of inbred lines with a higher yield potential and better quality fruit. For these purposes, 98 inbred lines of yellow melon and two commercial controls, Vereda and AF-646, were evaluated in a randomized block design with two replications, at the conditions present in Mossoró and Baraúna. Analyses of the following traits were performed: fruit yield, mean fruit weight, pulp thickness, pulp firmness and soluble solids content. A complex portion of the GxE interaction was predominantly detected for all traits. The recommendation in this case is to promote selection in each environment. Alternatively, selection based on the average behavior of the inbred lines is the strategy that generates the greatest gains, approaching those obtained through direct selection in each specific environment. The selection indexes aimed at reducing the expression of all traits proved to be best for both locations. The index constructed for Baraúna allowed the selection of a greater number of inbred lines with a higher yield potential and better quality fruit and, thus, greater efficiency.Keywords: Cucumis melo L, segregant populations, genetic gains, inbred lines extraction, hybrids, selection indexes.Interferência da interação genótipo por ambiente na seleção de linhagens de melão amarelo no agropolo Mossoró-Assu, Brasil RESUMO. Objetivou-se com esse estudo: i) identificar a interferência da interação GxE no processo de seleção de linhagens de melão e; ii) testar a eficiência de índices na seleção de linhagens com maior potencial produtivo e melhor qualidade de fruto. Para isto, avaliaram-se 98 linhagens de melão amarelo e duas testemunhas, Vereda e AF-646, em blocos casualizados com duas repetições, em Mossoró e Baraúna, localizadas no Agropolo produtor desta hortaliça. Avaliaram-se os caracteres produtividade de frutos, massa média de frutos, espessura de polpa, firmeza de polpa e sólidos solúveis. Detectou-se uma predominância da porção complexa na interação GxE em todos os caracteres. A recomendação, neste caso, é promover a seleção em cada ambiente. Alternativamente, a seleção baseada no comportamento médio das linhagens é a estratégia que gera ganhos mais próximos àqueles obtidos pela seleção direta em cada ambiente específico. Os índices de seleção, com o propósito de reduzir a expressão de todos os caracteres, se mostraram melhores para ambas as localidades. Àquele construído para Baraúna permitiu selecionar um maior número de linhagens com elevado potencial produtivo e com melhores qualidades de fruto, sendo assim, mais eficiente.

“…The interaction of SCA × Location was only significant for days to opening of the first female flower. Similar results regarding yield were demonstrated in melon (Cucumis melo L.; Feyzian et al, 2009). General and specific combining ability effects over location were recorded (Tables 4 and 5).…”

“…Diallele cross-designs are frequently used in plant breeding to obtain information and genetic effects for a fixed set of parental lines or to estimate GCA and SCA, which play an important role in control of yield-related components (Virk, 1988). Feyzian et al (2009) emphasized the need to screen parents and crosses before their use in breeding programs and suggested that combining ability analysis based on progeny test data, which is a useful method for evaluating parents and crosses for a wide range of quantitative characters, be used. This investigation was undertaken to determine the mechanism of gene action involved in inheritance of yield components in L. acutangula by combining ability analysis and evaluate effects of sowing date and location on gene expression.…”

The mating design (Line and Tester) has been extensively used to estimate general combining ability (GCA) and specific combining ability (SCA) variance and their effects. This design is also used to understand the nature of gene action involved in expression of economically important traits. Diallel analysis and combining ability in Luffa acutangula (L.) Roxb have not been extensively reported. Combining ability of 13 traits was examined in 45 Luffa hybrids derived from a 10 × 10 diallel mating design (excluding reciprocals) at two sowing dates and two locations. Additive and nonadditive genes were important for traits. The interaction of SCA × Location was not significant for traits except for days to opening of first female flower. Additive gene effects were more important for vine length, days to opening of the first male flower, number of male and female flowers/plant, number of nodes, number of fruit/plant, fruit length, fruit diameter, and number of seed/fruit. 'Slumber Long' was the best combiner, among 10 parental lines, for fruit yield/plant and fruit size. Crosses involving diverse parents and showing high SCA effects for fruit yield/plant have the potential to be utilized in Luffa improvement through simple recurrent selection.

The present study was carried out during successive growing seasons for the years 2014 and 2015, under greenhouse conditions, at Sabahia Horticulture Research Station, Alexandria Governorate, Egypt. Six inbred lines of cucumber were utilized in a half-diallel cross breeding program to obtain 15 F 1 hybrids. The breeding program was concerned with powdery mildew resistance, economic characters and their attributes; i.e. total fruit yield/ plant, number of fruits/plant and average fruit weight; in addition to the fruit quality characteristics; i.e., fruit length and fruit diameter. Results showed that the hybrid P 2 ×P 4 gave a very high resistance (100%), which is considered an immune (I) hybrid, while, the genotypes P 2 , P 1 ×P 2 , P 1 ×P 3 , P 2 ×P 5 gave high powdery mildew resistance (HR); i.e., (98.33%, 98.23%, 96.3% and 95.83%), respectively. The additive gene action exhibited highly significant, positive or negative, values in all the tested crosses for total yield/plant; whereas, the dominance effect values were found to be positively high significant in most crosses. The additive gene action exhibited positive significant values for powdery mildew resistance in most crosses; except the cross P 1 ×P 2 , which gave a negative high significant values and the two crosses P 1 ×P 5 and P 2 ×P 3 , which gave insignificant values. The dominance gene action was found to have positive high significant values in most crosses for this character.
