以品种型亲本、云瑞系列创新亲本和常用引进亲本选配35个生产性组合的有性世代为研究材料,分析母本、父本及组合的遗传效应。结果表明,母本、父本及其不同组合后代的主要性状均表现极显著差异,平均遗传力表现为组合(88.2%)>母本(80.3%)>父本(74.0%);德蔗93-88、云瑞05-189、云瑞05-344、CP84-1198、HOCP93-750、桂糖96-211、云瑞03-11、粤糖00-236、湛蔗92-126、桂糖92-66和云瑞03-72等做母本,科5、云蔗94-343、云瑞03-78、云瑞05-458、Q121和崖城71-374等做父本,后代糖、蔗产量或锤度一般配合力强,可分别作为高产、高糖亲本加以利用;CP84-1198×科5、德蔗93-88×云蔗94-343、云瑞05-189×云瑞03-78和云瑞05-344×云瑞05-458等11个组合糖产量的总配合力均为正效应,可作为杂交育种的优良组合利用。云瑞05-189、云瑞05-344、云瑞03-11、云瑞03-72、云瑞03-78和云瑞05-458等材料糖产量、蔗茎产量的一般配合力为正效应,具备了作为生产性亲本利用的潜力。
Genetic breeds of maternal, paternal and combination parents were analyzed using sexual generation with 35 productive combinations as parents, Yunrui series innovative parents and commonly used parents. The results showed that the main traits of female parent, male parent and their different combinations showed extremely significant differences. The average heritability was 88.2%> female (80.3%)> paternal (74.0%); -88, Yunrui 05-189, Yunrui 05-344, CP84-1198, HOCP93-750, Gui sugar 96-211, Yunrui 03-11, Guangdong sugar 00-236, Sugarcane 92-126, Gui sugar 92 -66 and Yunrui 03-72 as the female parent, Section 5, cloud sugarcane 94-343, Yunrui 03-78, Yunrui 05-458, Q121 and Yacheng 71-374 and other male parents, the offspring of sugar, sugarcane Yield or breeze general with strong, respectively, as high yield, high sugar parents to be used; CP84-1198 × Section 5, Takane 93-88 × cloud sugarcane 94-343, Yunrui 05-189 × cloud Rui 03-78 And Yunrui 05-344 × Yunrui 05-458 and other 11 combinations of sugar yield are positive effect with the combined yield, can be used as a good combination of cross breeding. Yunrui 05-189, Yunrui 05-344, Yunrui 03-11, Yunrui 03-72, Yunrui 03-78 and Yunrui 05-458 and other materials, sugar yield, cane yield and the general combining ability of positive effect , Has the potential to be used as a productive parent.
