摘要：

漯麦76是利用人工合成小麦进行多亲本阶梯杂交选育而成的小麦新品种。采用“强优势补短板”的原则配制亲本组合,运用“主抓重点性状,广选互补性状”的原则进行后代选择,聚合多亲本优点选育而成大粒高产小麦新品种。采用基因型主效加基因型-环境互作效应(GGE)双标图法和最佳线性无偏预测法(BLUP)评价其丰产性和稳产性。结果表明:漯麦76丰产性突出,两年平均产量和BLUP值均居小组前2位;GGE双标图也显示其具有优异的丰产性和较好的稳产性。产量三要素分析结果表明:漯麦76的667 m2穗数和穗粒数均在参试品种的平均值附近,但其千粒重水平显著高于平均值,且两年表现稳定,千粒重的提升是其高产的主要成因。

Abstract:

Luomai 76 is a new wheat variety bred through multi-parental stepwise hybridization using synthetic wheat. Parental combinations were configured based on the principle of “complementing weaknesses with strong advantages”, and progeny selection was conducted using the principle of “focusing on key traits while broadly selecting complementary traits”. This approach aggregated the advantages of multiple parents to develop this new large-grain, high-yielding wheat variety. Its high-yielding potential and stability were evaluated using the genotype main effect plus genotype-by-environment interaction (GGE) biplot method and the best linear unbiased prediction (BLUP) method. The results showed that Luomai 76 possesses outstanding high-yielding potential, with its two-year average yield and BLUP values ranking among the top two in its test group. The GGE biplot also indicated its excellent high-yielding potential and relatively good stability. Analysis of the three yield components revealed that the number of spikes per 667 m2 and the number of grains per spike in Luomai 76 were near the average of the tested varieties. However, its 1 000-grain weight was significantly higher than the average and remained stable over the two years. The increase in 1 000-grain weight is the primary factor contributing to its high yield.
