Abstract

A high-yielding and well-adapted wheat variety for central and peninsular India HD2932 was improved for three types of wheat rusts by introgressing genes Lr19/Sr25, Lr24/Sr24 and Yr10 and a new variety HD3407 (Unnat HD2932) was developed. The linked genes, Lr19/Sr25 and Lr24/Sr24, were derived from Thinopyrum (syn. Agropyron), whereas Yr10 was derived from Moro wheat (Triticum aestivum L.). NILs (> 90% RPG) with Lr19/Sr25 and Lr24/Sr24 in BC₂F₁ generation were intercrossed to produce two gene combinations Lr19/Sr25 + Lr24/Sr24. The two genes carrying plants were crossed with the third NIL with Yr10 for stripe rust resistance. Three-way cross NILF₁s were selfed and a large F₂ generation was produced to select plants with three genes. A single plant with all three genes in the homozygous state and maximum phenotypic and genotypic similarity (RPG = 98.14%) was identified and nominated in all India coordinated trials as HD3407. The proposed entry HD3407 yielded at par as that of the recurrent parent and check variety HD2932 during both the years of testing, 2020–21 and 2021–22, and displayed a high degree of resistance to leaf, stem and stripe rusts at seedling and adult plant stages. The average coefficient of infection for leaf rust (1.95), stem rust (3.45) and stripe rust (6.4) in HD3407 is found to be very low in artificial conditions in comparison with recurrent parent and check HD2932. Variety HD3407 (Unnat HD2932) was released for cultivation in 2023 for the central zone of India with Gazette notification S.O. 1056(E), dated 6th March, 2023.

标记辅助培育三重锈病抗性小麦品种 HD3407

通过导入 Lr19/SR25、Lr24/SR24 和 Yr10 基因，改良了印度中部和半岛的一个高产、适应性强的小麦品种 HD2932，以防治三种小麦锈病，并培育出新品种 HD3407（Unnat HD2932）。连接基因 Lr19/Sr25 和 Lr24/Sr24 来自 Thinopyrum（Agropyron 的同义词），而 Yr10 来自莫罗小麦（Triticum aestivum L.）。将 BC2F1 代中带有 Lr19/Sr25 和 Lr24/Sr24 的 NIL（> 90% RPG）进行杂交，产生了 Lr19/Sr25 + Lr24/Sr24 两个基因组合。携带这两个基因的植株与带有 Yr10 的第三个 NIL 杂交，以获得条锈病抗性。三向杂交的 NILF1 进行自交，并产生一个大的 F2 代，以筛选出带有三个基因的植株。在所有印度协调试验中，鉴定并提名了一株所有三个基因都处于同源状态、表型和基因型相似度最高（RPG = 98.14%）的植株为 HD3407。在 2020-21 和 2021-22 两个试验年度中，HD3407 的产量与复交亲本和对照品种 HD2932 相当，并在幼苗和成株阶段表现出对叶锈病、茎锈病和条锈病的高度抗性。与复交亲本和对照 HD2932 相比，HD3407 在人工条件下的叶锈病（1.95）、茎锈病（3.45）和条锈病（6.4）平均感染系数非常低。根据 2023 年 3 月 6 日第 S.O.1056(E)号公报通知，HD3407（Unnat HD2932）品种于 2023 年在印度中部地区推广种植。
