用混合线性模型方法对舢粳亚种间杂交组合农艺性状的相关性进行了遗传研究，结果表明：被测性状之间大都存在一定程度的相关．其中，株高与实粒数、结实率，穗长与总粒数、实粒数，总粒数与实粒数和结实率，以及实粒数与结实率之间具有显著的表型相关，总粒数与实粒数，实粒数与结实率，以及穗长与株高和结实率之间具有显著的遗传相关．进一步的分析表明，性状之间的遗传相关大多归因于显性效应，而粒重与穗长、总粒数和实粒数之间，以及总粒数与实粒数之间还具有极显著的加性相关
The genetic correlation was studied between agronomic traits of the hybrids between the japonica hybrids by using a mixed linear model. The results showed that most of the tested traits were related to some degree. Among them, there was a significant phenotypic correlation between plant height and grain number, seed setting rate, spike length and total grain number, grain number, total grain number and grain number and seed setting rate, grain number and seed setting rate, There was a significant genetic correlation between total grain number and grain number, grain number and seed setting rate, and spike length and plant height and seed setting rate. Further analysis showed that most of the genetic correlations between traits were attributed to the dominant effect, while grain weight and spike length, total grain number and real grain number, and between total grain number and real grain number were also significant Related to the additive
