摘要:
闽糖70-611是福建省农科院甘蔗研究所1970年以CP49-50×台糖134,从F1代中经“五圃制”选育出来的,系福建、云南两省继台糖134之后的第三代甘蔗当家种,18年来累计推广种植41.33万hm2,创社会效益7亿元。近年来该品种宿根性有所退化,生长后期蔗糖分有所下降,但由于它蔗皮较硬,遭受人为及虫畜损失较少,适应性广而仍然深受广大蔗农欢迎。为改进上述1～2个缺点,我们在地处亚热带的福建省漳州市成功地诱导闽糖70611开花,并配置了闽糖70611×斑茅(或刈手密),闽糖70611×甘蔗远缘F1和闽糖70611×栽培品种(或中间材料)三种类型杂交组合,并从中选育了一批有苗头的中间材料,为该品种的进一步改良,实现“世代前进”育种路线打下了基础。
Abstract:
Mint ang 70-611 came from F1 of CP49 50×F 134 a nd passed thr ough a“five seedling nursery”system to be selected and bred by Institute of Sugarcane,Fujian Academy of Agricultural Sciences in 1970.and has become amain cultiv ar as the third generation after F134 at Fujian and Yunnan provinces.It has accumutively distributed in 0.41 million hectar es area with 700 million yuan economic and social benefit Recently,its rato oning ability degener ate and sugar content descend at latemilling stage.So we induced Mintang 70-611 to bloom in a Zhangzhou city,and disposed 3 hybridized combinations:M int ang 70-611×Erianthus arundinaceum Retz(or Saccharum spontaneum L.),Mintang 70-611×Sugarcane distant F1 and Mintang 70-611×cultivars(or midmaterials).From the mentioned F1,Some good mid materials have been selected. So Mintang 70-611 is being improved and abreeding route of“gener ation progress”is brought about.
