| 摘 要： | 对甘蔗22个家系F_1群体的遗传变异分析表明,锤度是高度可遗传的品质性状,对选择有较大的响应.在锤度平均值高、遗传变异系数大的家系中选择高糖基因型的效果好,可获得较高的遗传进展.根据锤度与株高、茎径、茎数和丛重遗传相关的方向和程度,对不同家系高糖高产基因型的选择确定相应的策略,能达到选育高糖高产品种的最佳效果.

| Abstract: | Brix was found to be a quality character highly hereditable and responsive to selection by analysis of genetic deviations of F_1 populations in 22 sugarcane hybrid progenies. The efficiencies and expected gains for selection of high sugar genotypes would be better in the families which possessed high brix means and coifficients of genetic deviation. In order to achieve the best result for selecting sugarcane genotypes with high yield and sugar content, the strategies could be determined to different families based on the direction and degree of genotypic correlations between their brix and 4 yield attributes i. e. plant height, stalk diameter, millable stalks per clump and clump weight. |
