摘要
本文研究了粤农73－204×CP67－412新组合入选后代的表现。入选后代的新植蔗产量、亩含糖量及熟期与广东省的当家品种导糖63－237相当，其宿根性、抗逆性则更胜一筹。由于目前广东省蔗糖生产重点巴西移至对宿根性、早熟性及抗逆性要求较高的粤西高旱地蔗区，该组合应扩大播种量，以增加培育出一些优良新品种的可能性。
The performances of selected progenies of one new parental combination (Yuenong 73-204 ×CP67-412) were studied. The results showed that the cane yields and sugar yields of plant cane of these selected progen ies could be compared favourably with Yuetang 63-237 (a Guangdong lead ing commerc ial variety ). Ratooning ability and resistance of these selected progenies from the combination were much better than Yuetang 63-237. At present, with more sugarcane area moving to upland in west of Guangdong Province, the ratooning ability、early maturity and resistance of sugarcane varieties are more important. Seedlings of the combination should be expanded in order to increase the possibility of breeding new sugarcane variteties.
