摘要
由 Sakha 3 x Giza 2 杂交育成的单一蚕豆(Vicia faba L.)群体进行了两个周期的血统品系选择(PSM)。选择标准包括种子产量/株(SY/P)、荚数/株(NP/P)和种子指数(SI)。方差分析显示,在 F 3 代和 F 4 代中,各家系在所有研究性状上都存在显著差异,这表明选育工作取得了成功。值得注意的是,除开花日数外,所有性状的平均值从周期 1 增加到周期 2。开花日数呈现出相反的趋势,周期 1 的平均值更高。在 F 2 代中,SY/P 的预期选择收益(EGS%)为 29.52,在 F 3 代和 F 4 代中分别增加到 34.41 和 2.06。F 3 代 SY/P 的实现选择收益(RGS%)为 23.06,随后逐代下降,F 4 代为 9.56。在 1 号、2 号、13 号、56 号和 60 号系中发现了多个有潜力的蚕豆基因型。与较好的亲本、对照品种和大宗样本相比,这些家系的相对产量性状表现优异。此外,它们在大多数评估特征上都表现出良好的价值。这些研究结果表明,将它们纳入育种计划以提高蚕豆产量具有很大的潜力。
The Efficiency of Pedigree Line Selection in a Segregating Population (Sakha 3 × Giza 2) of Faba Bean (Vicia faba L.)
A single faba bean ( Vicia faba L.) population derived from the cross Sakha 3 x Giza 2 was subjected to two cycles of pedigree line selection (PSM). Selection criteria included seed yield/ plant (SY/P), number of pods/ plant (NP/P), and seed index (SI). Analysis of variance revealed significant differences among families within the F 3 and F 4 generations for all studied traits, indicating successful selection progress. Notably, mean values for all traits, except days to flowering, increased from cycle 1 to cycle 2. Days to flowering exhibited the opposite trend, with a higher mean value observed in cycle 1. The expected gain from selection ( EGS%) for SY/P in the F 2 generation was 29.52 and increased in the F 3 and F 4 generations in values of 34.41 and 2.06, respectively. The realized gain from selection ( RGS%) for SY/P in the F 3 generation was 23.06, then decreased in successive generation which amounted to 9.56 in F 4 . Multiple promising faba bean genotypes were identified within Families 1, 2, 13, 56, and 60. These families exhibited superior performance in relative yield traits compared to the better parent, check variety, and bulk samples. Additionally, they displayed favorable values for most characters assessed. These findings suggest their significant potential for incorporation into breeding programs to enhance faba bean yield.
