摘要:

对50份甘蔗栽培原种的宿根萌发率、分蘖率、株高、茎径、锤度、蔗糖分及自然条件下感病情况进行综合评价分析。结果表明:50份材料宿根萌发率为7%~184%,分蘖率为0~360%,宿根蔗中有效茎数、株高、茎径、锤度和蔗糖分值最高的材料分别是光泽竹蔗、四川芦蔗、拔地拉、德阳大叶子和28NG251。以各性状的前10份优异材料进行评价,筛选出21份含有2个以上优良性状的材料,含3个优良性状的有11份材料,含4个优良性状的有1份材料,其中以热带种14NG124的综合性状最佳。从感病率来看,中国种感染花叶病和黑穗病的比率高于热带种和印度种,其中德阳大叶子、广西竹蔗和文山蔗同时感染花叶病和黑穗病。

Abstract:

To evaluate the use of protospecies in the breeding of cultivated sugarcane, we examined 50 protospecies for ratoon character variation. Ratoon germination rate varied between 7% and 184%, and the ratio of productive tiller between 0 and 360%. The best materials in regard to effective stem, plant height, stem diameter, brix and sucrose were Guangze bamboo cane, Sichuan reed cane, badila, Deyang large leaves and 28NG251. Two good traits were exhibited by 21 protospecies, three good traits by 11 protospecies, and four good traits by 14NG124. Infection rate of S.sinense R by mosaic disease and smut was higher than in S.officinarum L. and S.barberi J. It was noted that Deyang big leaves, Guangxi bamboo cane and Wenshan cane were also infected by mosaic disease and smut.
