摘要
研究了几个斑茅后代作为甘蔗杂交亲本的利用效果,结果表明:崖城73/512是个优良父本,与CP72/1210杂交,后代表现突出,选出许多早熟、高糖、丰产、宿根性好的优良品系。崖城62/70和大茎丰产的粵糖57/423杂交,能选出优良品系。崖城64/389后代节间短、糖分较低,利用效果较差,应少用作亲本。从研究结果来看,斑茅在甘蔗杂交育种上的利用将是一条有效途径。
The utilization effect of several hybrid progenies of E.arundinaceus used as cane crossing parents was studied.The results showed that Yacheng 73/512 was a good male parent. The hybrid progenies performed most satisfactory and can be selected for many early-maturing, high sugar content, high yield and good ratooning varieties when crossed with CP72/1210. The progenies of Yacheng62/70 and Yuetang 57/423 ( a thick stalk and high yield variety ) can be selected for excellent lines. The progenies of Yacheng 64/389 had short internode and low sugar content. As crossing parent it should be reduced, because of its applied effect was undesirable. The results indicated that the use of E,arundinaceus in sugarcane breeding will be an effective pathway.
