四川甘蔗品种选育之对照品种选择的探讨

Discussion on Utilization of Check Variety Choice in Breeding Sichuan Sugarcane Varieties

根据气候条件和品种现状,四川盆地蔗区糖蔗品种选育,宜只选育早熟品种,用川蔗17号做对照品种;果蔗品种选育对熟期的要求并不严格,可用华南54-11;糖果兼用蔗品种选育,选育早熟品种,用川蔗23号,若选育中熟品种,则用川蔗6号;在攀西蔗区,糖蔗品种选育,应偏重早熟品种和中熟品种,早熟品种选育用桂糖1号做对照品种,中熟品种选育用川蔗6号,晚熟品种选育用川蔗13号。盆地蔗区不宜用川蔗13号做对照品种。

According to the climatic conditions and local sugarcane varieties in Sichuan basin cane area, it is suitable for selectively breeding early sugarcane varieties like Chuanzhe 17 as check variety; The ripe time＇s request is not strict for selective breeding chewing cane varieties, like Huanan 54-11 as check variety; About breeding of both sugar and chewing cane, Chuanzhe 23 is as check variety to selectively breed early cane varieties, and Chuanzhe 6 is as check variety to selectively breed medium varieties. In the Panxi cane area, it is suitable for selectively breeding early and medium sugarcane varieties, Guitang 1 is as check variety to selectively breed early cane varieties, Chuanzhe 6 is as check variety to selectively breed medium varieties, Chuanzhe 13 is as check variety to selectively breed late varieties. But the Chuanzhe 13 is not suitable as check variety to breed cane varieties in basin cane area.
