吉林省谷子主要推广良种和优良品系的系谱分析

本文对吉林省育成的谷子主要品种进行了系谱分析,认为育成的品种可划分“花脸”、“大青苗”两个衍生系统。花脸的后裔品种在农业生产中起主要作用,两个衍生系的品种对粟瘟病生理小种的抗性差异较大,两个衍生系品种均不抗A57和F1生理小种,选育品种的抗病性与亲本有密切关系。在今后的育种工作中,应利用花脸谷的适应性,改造它的抗病性,或者利用它的后裔品种,公谷6号,公谷7号,要注意对A57和F1生理小种抗源的引入。

GENEALOGY ANALYSIS OF THE PEDIGREES OF CER TIFICA TED VARIETIES AND GOOD STRAIN IN MILLET FROM JILIN PROVINCE

The certificated varieties were divided into two derivative systems Hualian and Daqingmiao, by analizing their genealogy. Hualian's offsprings have plaid an important role in the crop production. Resistance between varieties of the two derivative systems to millet blast was very different. However, hey were neither A_(5 7)-resistant nor F_1-resistant. There was a very consistent relationship between disease-resistances of developed varieties and their parents. The result primarily show that Hualian's disease-resistance should be improved by utilizing its adaptibity, while resistant source to A_(5 7) and F_1 blast should be introduced in the future breeding project.
