【摘要】

：

本试验在机械化种植条件下,以甘蔗品种桂糖42号为供试材料,设置肥料种类和施肥量2因子,肥料种类设置3个水平:缓释肥,氮、磷、钾化肥配施(以下简称NPK配施),复混肥;施肥量设置3个水平:低肥(每ha 施用 N 225kg、P205 90kg、K20 180kg),中肥(每 ha 施用 N 300kg、P205120kg、K20 240kg),高肥(每 ha 施用 N 375kg、P205 150k

以华占为背景的水稻染色体片段代换系的构建及重要农艺性状的QTL分析

水稻是世界上最重要的粮食作物之一,有超过一半的人口以稻米为主食。水稻大多数农艺性状是受多基因控制的数量性状,相关基因的鉴定和分离是开展水稻分子设计育种的前提和基础。染色体片段代换系(CSSLs,Chromosome segment substitution lines)的每个代换系只含有一个或少数几个来自供体亲本的片段,能够消除背景干扰,被认为是进行QTL分析的理想材料。本研究基于分子标记辅助选择
