广西甘蔗研究所自1957年至1986年从事甘蔗育种工作已经30年。先后育成了12个商业品种,其中以广西11为最好,推广面积达一百多万亩,占全区种蔗面积三分之一以上。 本所育成品种的亲本大多是CP49/50、F134和Co419,它们是S.officinarumL.×S.spontanenm L.×S.barberi Jesw.的后代。 应根据甘蔗种间杂交的染色体加倍规律和遗传变异原理来选配亲本,亲本必须是优良性状多,不良性状少,而后者可为另一亲本所弥补的。当地商业品种应作为重要亲本来源,因其一般具有较多优良性状,且适应当地环境。试探性组合的实生苗定植数一般以200株为宜,选择早熟品种时间宜早不宜迟,以10月为宜。一个有希望的组合在头几年如果能选出良种,不宜无限期地进行重复杂交。优良品种的选择标准是:早熟、高糖、长势好、中茎、实心、少或无病虫害、扫把尾、基部粗壮、宿根性强。
Guangxi Sugar Cane Institute from 1957 to 1986 engaged in sugar cane breeding work has been 30 years. Has bred 12 commercial varieties, of which the best of Guangxi 11, to promote an area of more than one million mu, accounting for more than one-third of the region’s cane area. The parents of the bred varieties are mostly CP49 / 50, F134 and Co419, which are the offspring of S. officinarum L. × S. sapontanenm L. × S. barberi Jesw. The parents should be selected according to the chromosome doubling rule and genetic variation principle of sugarcane interspecific hybridization. The parents must have many excellent traits and few bad traits, while the latter can make up for the other parents. Local commercial breeds should serve as an important source of parent because they generally have more good traits and are adapted to the local environment. The tentative combination of seedling planting number is generally 200 is appropriate, the choice of precocious varieties should not be late as soon as possible to October is appropriate. A promising combination In the first few years if you can choose a good breed, should not be repeated indefinitely hybridization. Selection criteria for elite varieties are: precocious, high sugar, growing well, stems, solid, less or no pests, broom tail, stout base, strong perennial.
