甘蔗新品种(系)闽糖97-301的选育与种性分析

Selection and Breeding of New Sugarcane Variety Mintang 97-301

闽糖97-301系福建省农业科学院甘蔗研究所从CP65-357×崖城84-153组合中选育出的1个甘蔗新品种(系)。多年多点试验结果表明,闽糖97-301平均蔗茎产量124.013t·hm-2,比对照种增产7.86%。11月至翌年1月平均蔗糖分15.40%,含糖量19.094t·hm-2,比对照种增糖11.74%,是一个丰产、高糖且农艺性状优良的中茎甘蔗新良种。稳定性分析表明该品种适应性较广,受环境影响因素较小;相关分析显示,有效茎数与株高(茎长)是影响该品种蔗茎产量的主要因素,对蔗茎产量贡献最大,高产栽培上可适当增加有效茎数和提高植株高度。

Mintang 97‐301 selected from the cross combination CP65‐357 × YC84‐153 was a new sugarcane cultivar with middle stem , high yield ,high sucrose content and wide adaptability. The results from different sites for several years showed that its mean cane yield was 124.013 t · hm ^-2 ,which was 7.86% higher than that of check.Sucrose content of cane was 15.40% during the period of Nov. to Jan. Sugar yield was 19.094t · hm^-2 ,which was 11.74% higher than that of check in Fujian Province. It was a wide adaptability cultivar ,not easily affected by the environment. Stalk number and stalk length were both the important factors of cane yield ,and their effects were the strongest to cane yield. In cultivation , we should place emphasis on increasing millable stalk and stalk length.
