再论关于加强我省水稻育种研究工作的几点意见

REDISCUSSION ON STRENGTHENING OF RICE BREEDING IN JILIN PROVINCE

摘要:

我省科研单位选育的品种由于抗病性不过关,生产上种植面积逐年减少,而由日本引进的品种栽培面积逐年扩大,据1984年统计,日本引进品种京引127,早锦和秋光种值面积占56.5%。生产上迫切需要抗病品种,科研单位目前还拿不出来,这是当前存在的主要问题。为了进一步加强水稻育种研究工作,尽快选育出高产、多抗、优质水稻新品种,本文从选育目标、技术路线、途径方法、加强稻瘟病生理小种研究和改进鉴定方法、建立优质米分析中心、以及加强横向联系和合作等方面进行了论述,并提出了改进意见。

Abstract:

Growing areas of varieties selected from our province gradually reduced because of less desease-risistance, while those of varieties introduced from Japen however adversely grew up yearly. According to statistics in 1984, the growing areas for cv. Jingyin 127, Zaojin and Qiuguang which introduced from Japen covered 56.5 per cent of the total areas. It was a kye problem that the varieties with desease-resistance were needed urgently whereas no such varieties have been supplied In order to further develop rice breeding, to study and select the new varieties with high yield, wide resistance and good quality, this discussions gave Some ideas of breeding goal, technical ways and methods, study of physiological race on rice blast and its improvement for identifying methods, establishment of analysis centre with good quality, development of crosswise relationship and cooperation as well.
