摘要
对 8 2 7份云南稻种核心种质结实率鉴定结果表明 :(1)初步筛选出抗旱品种 2 6 2份 ,占31.7%。 (2 )明确云南不同生态群间抗旱性的差异 ,其强弱依次为光壳群 (热带粳稻 (普通粳群(晚籼群 (早中籼群 (冬籼群。 (3)抗旱性强弱与水陆、颖毛有无密切相关 ,而与籼粳、粘糯关系不大。
Yunnan core collections were researched, the results show as follows:(1)262 drought-resistant rice cultivars were initially sifted through ,which were accounted for 31.7 percent. (2)Different drought-resistant in different ecological group in Yunnan were illustrated, ranking nuda >jivanica> communis> aman>aus>boro?(3)The strength and the wedeness of drought-resistant is highly related to paddy and upland?excoemum and glabrous, but it is nearly related to indian and japonion? non-glutinous and glutinous
