“…The magnitude of sca variance was greater than gca variance for all the traits ( Table 3). The obtained results are in accordance with the findings of Kashif and Khaliq (2003), Kamaluddin et al, (2007) but are in contrary with the findings of Akram et al, (2011) and Khan et al, (2007) who have reported the predominance of gca variance for the trait yield per plant. Further, the ratio of GCA to SCA variance was less than unity which indicated the preponderance of nonadditive gene action in controlling these traits.…”

“…Efeitos gênicos aditivos e não aditivos, no controle da expressão da produção de grãos em trigo, foram verificados na geração F 1 , por Kamaluddin et al (2007), e nas gerações F 1 e F 2 por Joshi et al (2004). Zeeshan et al (2013) constataram, por meio de análise dialélica, contribuição de efeitos gênicos não aditivos na geração F 1 superior a dos efeitos aditivos, para produção de grãos e seus componentes.…”

Resumo -O objetivo deste trabalho foi estimar, em gerações avançadas, os efeitos da capacidade geral e específica de combinação de genitores de trigo, bem como selecionar populações segregantes superiores. Doze genitores e suas 36 populações nas gerações F 2 e F 3 , obtidas em arranjo de dialelo parcial, foram avaliados quanto à produtividade de grãos. Utilizou-se o delineamento em látice 7x7, com duas repetições, mais um tratamento para completar o látice. O efeito de capacidade geral de combinação foi significativo, nas duas gerações. Observou-se alta correlação (0,83) dos efeitos de capacidade geral de combinação entre gerações, mas inexpressiva influência dos efeitos de gerações e de anos na classificação dos cruzamentos. As populações provenientes do cruzamento entre os genitores BRS 254, BRS 264 e IAC 364 (Tucuruí III) e os genitores MGS 1 Aliança, VI 98053 e UFVT 1 Pioneiro apresentam maior potencial para obtenção de linhagens superiores, quanto à produtividade de grãos. O uso da análise dialélica parcial em gerações avançadas é promissor para programas de melhoramento de trigo por hibridação.Termos para indexação: Triticum aestivum, capacidade de combinação, melhoramento de plantas, predição do potencial genético. Partial diallel analysis in advanced generations for selection of wheat segregating populationsAbstract -The objective of this work was to estimate the effects of general and specific combining ability of wheat parental lines in advanced generations, and to select superior segregating populations. Twelve parental lines and their 36 populations in F 2 and F 3 generations, obtained in a partial diallel arrangement, were evaluated for grain yield. The experimental design used was a 7x7 simple lattice with two replicates, plus a treatment to complete the lattice. The effect of general combining ability was significant in both generations. There was high correlation (0.83) of the effects of general combining ability between generations, but inexpressive influence of the effects of generations and years were observed on the classification of crossings. The populations derived from the crossings between the parental lines BRS 254, BRS 264, and IAC 364 (Tucuruí III) and the parental lines MGS 1 Aliança, VI 98053, and UFVT 1 Pioneiro show the greatest potential for obtaining superior lines for grain yield. The use of the partial diallel analysis in advanced generations is promising for wheat breeding programs through hybridization.

“…Yan and Hunt (2002) evaluated the GCA of parents and the SCA of the crosses via a diallel design under multiple environments. The higher contribution of GCA effects has been linked to the additive effects that controlled expression of the traits in wheat (Kamaluddin et al, 2007). Kumar et al (2011) identified the best specific and general combiners that were efficient for breeding days to flowering and grain yield per plant in seven bread wheat cultivars.…”

Wheat maturity is important for its adaptability to different environments and geographical regions. In order to obtain genetic information for maturity and grain yield, five wheat cultivars of Cross adl, Marvdasht, Chamran, Shiraz and Darab2 were crossed for producing one-way diallel crosses that were analyzed using two models of Griffing (1956) and Jinks and Hayman (1953). Parents and their F 2 progenies were cultivated at two locations of Shiraz and Zarghan, Iran, in 2010-2011. The traits of interest were days to heading (DDH) and maturity (DDM), grain filling duration (GFD), grain yield per plant (GY) and plant height (PH). Genotype × location interaction was significant for PH and GFD but there was no interaction for DDH, DDM and GY. The variances due to general (GCA) and specific (SCA) combining abilities were significant for all the traits. Therefore, both additive and non-additive genetic components were not equally involved in genetic control of the characters studied. The GCA × location interaction was only significant for PH and GFD, an indication for the effects of environment on additive components. The Baker (1978) ratio for DDH (0.90 and 0.91 at Zarghan and Shiraz locations respectively), DDM (0.81 and 0.82) and GY (0.89 and 0.87) under both locations and for PH (0.88) at Shiraz showed the higher importance of additive variances in the genetic control of these traits. The GCA estimates revealed that Chamran for dwarfness, early heading and maturity and GFD, Darab2 for dwarfness, early heading and maturity, Marvdasht for GFD and GY were the best combiners. Graphical analysis and the average degree of dominance (less than 1) showed that gene action for all the traits was of partial dominance type.
