| 摘 要： | 1986-1990年,本研究在利用日本9个鉴别菌系和国内7个菌系对近300个品种进行抗性分类,并在鉴定出71个单基因品种的基础上,选出19个分属8种基因型的云南粳稻品种,进一步以日本9个为一套的单基因鉴别品种作对照,用云南35个菌株测定,筛选出丽江新团黑谷(Pi-ks)、云玉一号(Pi-a)、高梁程(Pi-i)、关东51(P1-k)、楚粳1号(Pi-km)滇榆1号×福锦(Pi-z)、大理782(Pi-ta)、单83-3(Pi-ta2)、城堡1号(Pi-zt)等9个为一套的单基因鉴别品种。日本和我们新筛选的两套鉴别品种,以云南35个菌系进行接种测定,可划分出相同的17个小种,这说明新筛选的9个单基因鉴别品种具有日本9个单基因鉴别品种同等鉴别能力。新筛选出的9个单基因鉴别品种和我国7个鉴别品种用这35个菌株接种,前者可划分出17个小种,后者只划分出9个小种。结果表明,新筛选出的单基因鉴别品种在鉴别能力方面明显优于我国7个鉴别品种。

| Abstract: | On the basis of the 71 monogenic rice Varieties that were identified from near 300 Varieties by resistance classification studies using 9 Japanese differential strains and 7 domestic strains of blast fungus.We screened 19 monogenic varieties of Yunnan's Japonicatype which belong to 8 genotypes respectively.Using 9 Japanese monogenic varieties and 35 Yunnan fungus strains in the tests,a sed of 9 monogenic varieties including Lijianxintuan-heigu(Pi-Ks),Yunyu No.1.(Pi-a),Gaoliangdao(Pi-i),Kanto 51(Pi-k),Chujing No.1(Pi-km),Dianyu No.1 X Fukunishiki(Pi-z),Dali.782(Pi-ta),Dan 85-3(Pi-ta2),Toride 1(Pi-zt) were screened. |
