摘要

摘要: 目的高产、优质、抗病、抗倒伏等育种目标是当前水稻新品种培育普遍关注的热点。方法采用传统技术与分子育种相结合，鉴定并评价高产、抗病、低直链淀粉含量、高碱消值的糯稻新种质，筛选出综合性状优异的株系。采用不完全双列杂交（NC II）方法，构建亲本及20个杂种一代的遗传群体，评价糯稻亲本及杂交组合产量和品质性状的育种利用价值。结果 7个优良品系的实割产量变幅34.42 kg·hm⁻²～40.96 kg·hm⁻²，其中X-104实割产量最高，达40.96 kg·hm⁻²，X-27实割产量达34.42 kg·hm⁻²，明显优于3个对照；两个株系植株矮壮，且分别携带了Pi-1、Pi-k^h和Pi-1、Pi-9、Pi-k^h的稻瘟病抗性基因，表现为中抗稻瘟病；AC分别为1.71%和1.68%；碱消值达6.75级和6.13级，育种价值高。在杂种优势利用上，X-27除了株高性状一般配合力为正效应外，该株系有利提高杂种后代的产量与稻米品质。X-57具有降低后代的株高和AC，提高后代产量和碱消值。X-104虽产量高，品质好，但不利于杂种优势利用。闽糯2S/X-41、闽糯2S/X-107在产量、株高、AC及碱消值等性状上具有明显的超亲优势和竞争优势，在杂交糯稻上应用价值高。结论杂交糯稻的产量与品质均为复杂性状，其中有效穗数、穗长、千粒重、长宽比、单株产量、AC、碱消值主要受糯稻恢复系的控制。各性状的广义遗传率（h²_B）变幅14.72%～53.99%，狭义遗传率（h²_N）变幅10.25%～43.07%，遗传率较低，易受环境影响。育种上需大量配组，方可培育出不同用途的专用型糯稻杂交稻。

Abstract: Objective The breeding goals of high yield, high quality, disease resistance and lodging resistance are the focus of attention in the breeding of new glutinous rice varieties. Method In this study, some new glutinous rice germplasm with high yield, disease resistance, low amylose content and high alkali loss value were identified and evaluated, and some lines with excellent comprehensive traits were selected through the combination of traditional technology and molecular breeding. Using the incomplete diallel crossing (NC II) method, parental lines and 20 hybrid populations were constructed to evaluate the breeding value of yield and quality traits in parents and hybrid combinations. Result The actual yield of 7 excellent strains ranged from 34.42 kg·hm⁻² to 40.96 kg·hm⁻². The actual yield of X-104 was the highest, reaching 40.96 kg·hm⁻², and the actual yield of X-27 was 34.42 kg·hm⁻², which was obviously better than the three controls. The two strains were short and stout, and carried the blast resistance genes of Pi-1, Pi-k^h and Pi-1, Pi-9 and Pi-k^hrespectively, showing moderate resistance to rice blast. AC was 1.71% and 1.68%, respectively. Alkali elimination value was 6.75 and 6.13, which had high breeding value on conventional glutinous rice. In the utilization of heterosis,in addition to positive general combining ability for plant height, restorer line X-27 also contributed to increased yield and rice quality in hybrid progeny. X-57 reduced plant height and AC in the progeny while increasing yield and alkali digestion value. X-104 exhibited high yield and good quality, but it is not conducive to heterosis utilization. Minnuo 2S/X-41 and Minnuo 2S/X-107 have obvious superrelative and competitive advantages in yield, plant height, AC and alkali loss value, and have good application value in hybrid glutinous rice. [Conlusion] The yield and quality of hybrid glutinous rice were complex characters, among which the effective panicle number, panicle length, 1000-grain weight, length-width ratio, yield per plant, AC and alkali loss value were mainly controlled by the restorer line. The broad heritability (h²B) and narrow heritability (h2N) varied 14.72% ～ 53.99%, and the narrow heritability (h²N) varied 10.25% ～ 43.07%, which were low heritability and easy to be affected by environment. Special glutinous rice hybrid rice suitable for different uses can be cultivated by a large number of combinations in breeding.
