摘要： 以泸恢8258为父本选育并通过审定的6个组合及其相对应的保持系为材料，分析泸恢8258系列组合的品质特性，及泸恢8258对杂种一代品质的影响。结果表明，泸恢8258系列组合垩白粒率低，直链淀粉含量适中，长宽比较大；泸恢8258可以降低杂种一代垩白粒率和直链淀粉含量，增加长宽比。

Abstract: The quality property with series combinations from Luhui 8258 and impact of hybrids from the parents of Luhui 8258 were analysed using 6 combinations and its parents as material. The results showed that Luhui 8258 series combinations were low chalky  rice rate, moderate amylose content, larger length-width ratio. Luhui 8258 can reduce chalky rice rate and amylose content of hybrids, and increase length-width ratio.

Key words: rice, Luhui 8258, quality, chalky rice rate, amylose content
