| 摘 要： | 目的]明确两系杂交水稻两优2111产量与重要农艺性状之间的相互关系.方法]依据在云南省6个州市(县)两优2111的种植表现,运用主成分分析方法分析了两优2111的产量及其与10个重要农艺性状的相关关系.结果]影响两优2111产量的最主要因素是穗粒数、实粒数、穗长、生育期和成穗率;其次是千粒重、结实率、有效穗和最高茎蘖数;再次是株高.结论]两优2111在云南省各籼稻区推广种植时,应着重保证其穗部性状尤其是穗粒数和实粒数的增多,协调其他性状的发展以实现高产.

| Abstract: | In order to define the relationship between yield and important agronomic traits of two lines hybrid Liangyou 2111,the principal component analysis method was used to analyze the experimental data of six test points in Yunnan Province.The results showed that the main factors influencing the production of Liangyou 2111 were grain number,grains seed number,panicle length,growth period and panicle rate;then were 1 000-grain weight,seed setting rate,effective panicle and highest stem tillers number;again was plant height.Therefore,when hybrid rice of Liangyou 2111 will be planted widely in yunnan province,we should focus on ensuring the panicle traits,especially increase grain number and grain seed number,and coordinately develop other traits to achieve high yield. |
