糯小麦种质资源宁W0065的评价与利用

为了解引进的糯小麦新品系宁W0065的利用价值,对其农艺性状、抗病性和支链淀粉含量进行了分析鉴定。研究结果表明,宁W0065具有株高偏高、穗长偏短、千粒重偏轻、生育期偏晚及易感白粉病等缺点,不能在四川生产上直接利用。不过,宁W0065具有分蘖力强、成穗率高及纯糯的特点,可作为优异种质资源加以利用。

Evaluation and Utilization of the Waxy Wheat Germplasm Ning W0065

Aiming at evaluating the practical utility of the waxy wheat line Ning W0065,the current research assessed its agronomic traits and disease resistance,and also determined its amylopectin content.Relative to the control,Ning W0065 showed greater plant height,smaller spike length,lower 1000 -kernel weight,later maturity,and higher susceptibility to powdery mildew.Thus this line cannot be directly used for wheat production in Sichuan Province.On the other side,Ning W0065 exhibited some good characters:greater numbers of tiller,effective spike per plant,and being purely glutinous.Hence,it could serve as an excellent germplasm re-source for wheat breeding.
