9个两系杂交水稻组合在四川的产量性状和米质表现

本文对9个两系杂交水稻组合在四川种植时的主要产量性状和米质性状进行了分析。结果表明,广占63S/R9348组合产量最高,33S/9311组合最低。Y58S类组合穗粒库容较大,每穗实粒数较多,是该类组合增产的主要原因。广占63S类组合每平米有效穗数最多,结实率较高。33S类组各主要产量性状优势不明显。Y58S/R9348组合达优质米3级,两系杂交稻组合在主要品质指标上均优于对照品种。...

Summary:本文对9个两系杂交水稻组合在四川种植时的主要产量性状和米质性状进行了分析。结果表明,广占63S/R9348组合产量最高,33S/9311组合最低。Y58S类组合穗粒库容较大,每穗实粒数较多,是该类组合增产的主要原因。广占63S类组合每平米有效穗数最多,结实率较高。33S类组各主要产量性状优势不明显。Y58S/R9348组合达优质米3级,两系杂交稻组合在主要品质指标上均优于对照品种。

The main yield and rice quality traits of 9 two-line hybrid rices in Sichuan were analyzed. The results showed that Guangzhan 63 S /R9348 had the highest yield,and minimum yield in 33 S / 9311. Y58 S lines had longer panicles,more filled grains and higher seed setting,which were major reasons to improve yield for Y58 S lines as female. Guangzhan 63 S had the most effective panicles,and there was not obvious advantage for major yield traits in 33 S lines. Y58 S / R9348 had good quality in level 3. Generally speaking,the main quality indicators of two-line hybrid rice were better than that of CK.
