2011年甘蔗实生苗试验结果分析

Results of the Sugarcane Seedling Populations Trial in 2011

对2011年甘蔗实生苗试验进行了分析。结果表明,各组合和各亲本之间在5个性状方面均达到差异显著或极限著水平,其中,以粤糖89-240、CP89-2143等作母本,或以粤糖93-124、粤糖91-976和CP94-1100等作父本,以及配制组合粤糖89-240×ROC22,它们的实生苗后代丛重和甘蔗糖分表现较好。各参试家系表现不一。

Results of the sugarcane seedling populations trial in Zhanjiang region in 2011 showed that there was significant or very significant difference in 5 characters among both the parents and the crosses. The hybrids of Yuetang 89-240 and CP 89-2143, which were crossed as the female parent, and Yuetang 93-124, Yuetang 91-976 and CP 94-1100, which were crossed as the male parent, had a better performance in both the cane yield per plant and cane suger than those of the other male or female parents; On the other hand, to the hybrids of Yuetang 89-240 especially when it was crossed with ROC22, both their cane yield per plant and cane suger was good. The performance of these parents and crosses was diverse.
