粳稻体细胞耐冷变异的诱导技术与遗传特性

Hereditary Characters and Inducing Technology ofSomatic Cold Resistance Variation of Japonica Rice

摘要:

近年来,利用植物组织培养技术,已在多种农作物中获得抗病、耐盐碱、抗除草剂等抗逆性变异体,并阐明了部分遗传变异特性。本文综合报道获得粳稻体细胞耐冷变异体的诱导筛选技术、遗传变异特性及用本项技术育成的粳稻新品种(系)在大面积水稻生产上的示范应用事例。

Abstract:

in recent years, by using plant tissue culture technology,many stress resistance variant, such as disease, salt and herbicide resistance, have been obtained in manycrops, and part of the hereditary variation characters have been explicated. The inducingand selecting technique and hereditary variation character of cold resistance variant ofJaponica Rice is reported,the application situation of new rice varietie bred by tissue culture is also reported.
