摘要
对74个云南高原粳稻亲本的经济性状和品质性状的测定结果进行了相关性分析,结果表明:①株穗数与整精米率和胶稠度呈极显著正相关,与直链淀粉含量和糊化温度呈显著负相关。②千粒重与外观品质呈极显著负相关,与糙米率、直链淀粉含量呈极显著和显著正相关。③穗实粒数与品质性状间的相关性不显著。并讨论了在云南高原粳稻区选育及栽培高产优质粳稻品种的途径。
The correlation analysis between economic traits and grain quality traits in Japonica rice of Yunnan plateau were carried out by using 74 breeding parents. The results indicated that： （ i ） Panicles per plant was highly positively Correlated with head rice rate and gel consistency and negatively correlated with amylase content and ADV. （ii） 1000-grain weight was highly negatively correlated with appearance quality and highly positivety correlated and positively correlated with brown rice rate and amylase content. （iii）There was no significant correlation between filled spike.lets per panicle and grain quality traits. It was discussed about how to develop and cultivate cultivar with highly yield and good grain quality in Yunnan Japonica rice region
