“…This finding is inconsistent with previous studies reported by Khan et al (1991), Smith (1997), Shakeel et al (2001), Turgut (2003), andLukonge et al (2008). The results indicated that a higher GCA does not necessarily confer a higher SCA and that the GCA and SCA were independent of one another a finding similar to the results of Khan et al (2007) and Khan et al (2009). In this study, the hybrid combinations with positive and significant SCA effects produced a high mean value of certain traits (e.g., Aydin-110 × Sahin-2000 for S/B and GW Teks × Carmen for L/S).…”

“…The relative importance of the non-additive effects suggests that selection should be applied in advanced generations of the breeding program. Moreover, simple selection in top performing hybrids can also be studied by further segregating generations (Saeed et al, 2000;Cruz et al, 2006;Khan et al, 2009). Previous studies show that yield and yield components were influenced by non-additive (Shakeel et al, 2001;Ahuja and Dhayal, 2007) and some researchers found that both additive and non-additive gene effects influenced yield and yield components.…”

The major problem with the simultaneous improvement of yield with higher fiber quality is the negative association due to the linkage and pleiotropic effects between lint yield components and fiber quality parameters. The objectives of this research were to estimate the general combining ability (GCA) of parents and specific combining abilities (SCA) of hybrids for fiber quality parameters and within-boll yield components, and to determine the association of fiber quality parameters with basic within-boll lint yield components. In this study, eight cotton cultivars and 15 F 1 hybrids obtained by crossing five lines and three testers in the line × tester mating system during 2006 were planted in a randomized block design with four replications in 2007. The predominance of non-additive gene action was estimated for all traits except for the upper half mean fiber length (UHM), fiber strength, and seeds per boll, which were controlled by an additive type gene action due to the high GCA variance. Among the parents, 'Askabat-100' and 'Carmen' were the best general combiners for fiber length, strength, and uniformity index (UI). Additionally, 'GW Teks' and 'Sahin-2000' were determined to be good combiners for lint weight per seed (L/S) and spinnable fibers per seed (F/S). The SCA effects showed that the best specific combination was 'Sealand-542' × 'Sahin-2000' and 'TAM 94L-25' × 'SG-125' for lint percentage, L/S, and lint weight unit per seed surface area. The most important fiber quality parameters, UHM, fiber strength, and UI, were negatively associated with the most basic within-boll lint yield components, L/S, and F/S.

Inheritance, general combining ability and specific combining ability were studied using four parents: FH-901, NIAB-Karishma, CIM-496 and MS-84 for different plant traits in Upland cotton (Gossypium hirsutum L.). Mean values of all genotypes were significantly different from each other for all the traits studied. Epistasis was not found to be involved in any of the traits. The inheritance of all the traits was controlled by additive type of gene action with partial dominance except seed cotton yield that was controlled by over-dominance type of gene action. It was further noticed that the parent MS-84 was best general combiner for the traits like plant height, number of monopodial branches and number of bolls. The cross MS-84 × NIAB-Karishma showed greater specific combining ability for plant height, number of monopodial branches and number of sympodial branches.

“…To introduce genetic variability, diallel crossing techniques have been widely utilized by breeders (Basal and Turgut, 2005;Basal et al, 2009;Khan et al, 2009a,c). Consequently, the use of genotypes with desirable genetic components of variance is a prerequisite for synthesis of physiologically efficient and genetically superior genotypes showing promise for increased production per unit area under a given set of environments (Khan et al, 2009a). To achieve these objectives using quantitative genetics, workers have advocated a comprehensive study of assumptions of additive-dominance model (through different scaling tests), genetic mechanism and genetic components of variation which control the various plant characters in parents and their cross combinations under various environmental conditions (Hayman, 1954;Mather and Jinks, 1982;Tang et al, 1993Tang et al, , 1996McCarty et al, 1996McCarty et al, , 2004aHussain et al, 1999;Khan, 2003;Ragsdale, 2003;Lukonge, 2005;Mei et al, 2006;Wu et al, 2006;Esmail, 2007;Lukonge et al, 2007;Khan et al, 2007Khan et al, , 2009aAguado et al, 2008;Ali et al, 2008;Ali and Awan, 2009;Basal et al, 2009;Gamal et al, 2009).…”

The nature and magnitude of genetic effects on morpho-yield traits were studied in a 6 × 6 F 1 and F 2 diallel cross in upland cotton. An additive-dominance model was adequate for most of the traits except plant height and seed cotton yield, where the model was partially adequate. Genetic parameters were estimated following Hayman's and Mather's model. Additive effects controlled lint percentage and monopodia in both generations, and plant height and sympodia in F 2 . Non-additive inheritance with over-dominance controlled yield in both generations, and plant height and sympodia in F 1 . Most traits presented an unequal proportion of positive (U) and negative (V) alleles in the loci (H 2 < H 1 ) and an asymmetrical distribution of genes in the parents (H 2 /4H 1 < 0.25 and F different to zero). The value of H 2 /4H 1 was lower than maximum value (0.25) for all of traits, which arises when U = V = 0.5 over all loci. The proportion ͌ʳʲ 4DH1 ʲʲ + F ʲ/͌ʳʲ 4DH1 ʲʲ -F ʲ) confirmed by half of the traits that dominant alleles were in excess as compared to recessive alleles. Dominance effects (h 2 ) for most of the traits suggested that substantial contribution of dominance was not due to heterogeneity of loci in these parameters. Broad and narrow sense heritabilities were high for most of the traits. Correlation coefficient between the Wr + Vr and mid parental (y) indicated that dominant genes were responsible for increased sympodia, lint % and yield, and recessive genes increased monopodia and plant height. Genetic gain was encouraging for most traits. Cultivar CIM-1100 was identified by genetic advancement as a promising parental cultivar to cross combinations.Additional key words: additive-dominance model; additive and dominance effects; D, H 1 & H 2 genetic components of variance; seed cotton yield; upland cotton. ResumenEfectos genéticos en caracteres morfológicos y de rendimiento en algodón (Gossypium hirsutum L.)Se estudió la naturaleza y la magnitud de los efectos genéticos sobre los caracteres morfo-productivos en un cruce dialélico F 1 y F 2 de 6 × 6 en algodón tipo upland. Para la mayoría de los caracteres, excepto altura de planta y rendimiento de semilla, fue adecuado un modelo aditivo-dominante. Se estimaron los parámetros genéticos según Hayman y Mather. Los efectos aditivos controlaron el porcentaje de pelusa y los monopodios en ambas generaciones, y la altura de la planta y los simpodios en la F 2 . La herencia no aditiva con superdominancia controló el rendimiento en ambas generaciones y la altura de planta y los simpodios en la F 1 . La mayoría de los caracteres presentaron una proporción desigual de alelos positivos (U) y negativos (V) en los loci (H 2 < H 1 ) y una distribución asimétrica de los genes en los parentales (H 2 /4H 1 < 0,25 y F 0). El valor de H 2 /4H 1 estuvo por debajo del valor máximo (0,25) para todos los caracteres, lo que surge cuando U = V = 0,5 en todos los loci.
