Avaliação de dez linhagens e seus híbridos de milho superdoce em um dialelo completo

Abstract: Milhos doces (Zea mays L.) são caracterizados por grãos com altos teores de açúcares e pouco amido no endosperma, o que os torna enrugados e translúcidos quando secos. A doçura é um caráter recessivo (Wallace & Bressman, 1949) e os genes mutantes mais conhecidos são o sugary (su), shrunken (sh) e brittle (bt). Os genes bt e sh acumulam açúcares às expensas de amido e apresentam teores muito baixos de carboidrato total no estágio de maturação. Devido aos elevados teores de açúcares, as cultivares dos genótipos … Show more

“…Significant effects found in GCA and SCA for all traits, in two sowing dates, show that both additive and non-additive effects were important for genetic control of studied traits (Table 1). Similar results for ear yield, grain yield, plant height and total soluble solids were obtained by Lemos et al (2002); Bordallo et al (2005), Solomon et al (2012, Rice & Tracy (2013) and Suzukawa et al (2018). However, for ear height and ear diameter, Solomon et al (2012) reported that additive gene action had greater importance in relation to non-additive effects, and for TSS, the authors verified no significant difference for GCA and SCA in diallel crosses evaluated, whereas Yuwono et al (2017) verified significant difference of SCA for TSS.…”

“…The h contributed positively to TEW, with a parent yield of approximately 6798.416 kg ha -1 (Table 4), indicating that the mean yield of F 1 was higher, corresponding to 88.91% of the parental mean (Table 3). Lemos et al (2002) worked with sweet corn lines and their hybrids, and found heterosis values in the crosses for TEW, which ranged from -26.43% to 117.51% of the parental mean.…”

“…Some researchers have prioritized the study about variables associated with corn ears with no straw; however, the variables associated with corn ears with straw are undoubtedly the most important ones to the industry, since corn ears are traded per unit with straw due to the transportation and conservation of sugars (Lemos et al, 2002). The indices of these straw-related variables should show 50% increase when they are compared to the variables found in corn ears with no straw.…”
