本文以豫麦13(郑州891)为例,结合黄淮麦区和长江中下游麦区大面积丰产品种表现,就此类品种的性状要求和育种特点进行一些阐述,供小麦育种工作者参考。一、豫麦13在不同环境条件下的表现豫麦13在河南省区试中连续三年名列第一、二位,平均亩产400多公斤,比对照增产10%以上;在黄淮南片和北片大区区试也均居第一、二位,表现高产、稳产。从地点分布来看,在1990年、1991年多病受灾之年,除淮河以南和烟台地区为其不适应区表现减产外,在陕西武功、山西临汾、山东 Taking Yumai 13 (Zhengzhou 891) as an example, this paper described the traits and breeding characteristics of the varieties in Huanghuai wheat area and the middle and lower reaches of the Yangtze River, and provided some references for the wheat breeding workers. First, Yumai 13 performance under different environmental conditions Yumai 13 in Henan Province for the third consecutive year in the trial ranked No. 2, with an average yield of more than 400 kilograms, more than 10% increase in yield control; And the northern area large area test also ranked first, two, the performance of high yield, stable production. From the point of view of distribution, in 1990 and 1991, the year of catastrophic disease, except for the areas south of the Huaihe River and Yantai, and the reduction of output in areas unsuitable for them, the Wugong in Shaanxi, Linfen in Shanxi, Shandong
