摘要：

摘要：以粳稻品种秀水11、日本晴为材料，利用30Gy60Coγ射线辐照其成熟胚愈伤组织，在MR2代观察到叶片、茎秆、籽粒和穗等形态性状发生变异的突变体以及育性和生育期等生理性状方面的变异株；这些突变体为水稻功能基因组学研究和新品种选育提供良好的基础材料，其中一些突变体在水稻生产上有较高的应用价值。

Abstract:

Abstract:Callus induced from mature embryos of japonica rice varieties “xiushui11” and “Nipponbare” were irradiated with 60Coγ-rays at the dosage of 30Gy. Morphological variations including leaf, stalk, seed, panicle at vegetative and reproductive stages and various physiological characters were observed in MR2 generation. These mutants will be helpful for gene identification and gene functional analysis as well as breeding of new rice variety. Some variant plants show high potential in rice production.
