高配合力、优质恢复系泸恢8258系列组合品质分析

Quality Analysis of Restorer of Luhui 8258 with High Quality and Combining Ability and its Series Combinations

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。

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.
