摘要
在亚热带地区采用光周期处理诱导热带种果蔗开花 ,并与野生蔗割手密及斑茅蔗进行种间杂交。获得并入选的杂种后代 98/ 2 5、98/ 2 6- 1、98/ 2 6- 2经叶片酯酶同工酶和综合农艺性状分析 ,初步认定是杂交种 ;而且各具有可利用的优良性状 :98/ 2 5生物产量特高可作为高生物产量品种利用 ,98/ 2 6- 1、98/ 2 6- 2趋向于母本栽培型 ,特别是 98/ 2 6- 1田间锤度已接近母本 ,又兼具父本的有利基因 ,可作为优良新本。
Saccharum officinarum L. Chewing cane was induced to flower by photoperiod treatments in subtropical area, and hybridized with wild S. spontaneum L. and wild S. arundinaceum Retz. Esterase isoenzyme and agricultural properties synthetical analysis of three hybrid progenies including 98/25, 98/26 1, 98/26 2 implied that they were crossbreed with virtue properties. The biological production of 98/25 was very high, which could be used as a high biological production variety. 98/26 1 and 98/26 2 tended to be matermal cultivar. The brix of 98/26 1 was close to female parent, and it had advantageous genes of male parent, which maked it could be used as a good parent.
