摘  要:
估算了甘蔗(Saccharum officinarum L.)三个主要经济性状的遗传相关及其与环境互作的大小。结果表明,每英亩蔗产量与每英亩糖产量有强的基因型相关,而与每吨蔗的糖产量却没有这种关系。遗传参数的分析还表明,每英亩蔗产量具有最大的遗传进度,而每吨蔗的糖产量重复力最大。故甘蔗品种改良中,同时提高品种单位面积的蔗产量和单位蔗量的糖产量是可获得的。因子分析的结果说明,每英亩蔗产量和每吨蔗的糖产量之基因型方差都达显著水平;不同土壤类型和新植蔗及宿根蔗的互作都影响着每英亩蔗产量、每英亩糖产量和每吨蔗的糖产量的表型方差。因此,在甘蔗育种中要提高育种最后阶段的选择效率,排除环境因子的影响是很重要的。

摘  要:
Heritabillty , correlation and interaction of genotype-environment for three economic characters in sugarcane (S.officinarum) were calculated. The results indicated that cane yield/acre had a strong genotypic correlation with sugar yield/acre and had not important correlation with sugar yield/ton of cane.The analysis of heritabillty parameters indicated that cane yield/acre had greast value of relative gain from selection (△ G') among three characters studied. The estimates of variance with factorial analysis showed the variation of genotypes in cane yield/acre and sugar yield/ton of canehad sinifieant differences and the interaction of soil x cane types affected the total phenot-ypk variations of sugar yield/acre, respectively. It is important to remove the effects of environment factors for improving clonal selection efficiency in sugarcane breeding.
