小麦良种博爱74—22是河南省博爱农场从7023中选变异株育成的。1978年秋在我地区高肥组区域试验中居第二位,较对照种郑引1号增产6.2％;1979年在全省高肥组区域试验中,宿县、阜阳点分别比郑引1号增产2.23％和12.1％,居第二、一位,在淮南片也居首位。1980年秋示范推广,1981年秋在我地区种植面积达14.5万亩,1982年面积继续有所扩大。这个品种属于半冬性,叶片直立,株高中等;穗大、粒多、粒重;较抗倒伏,抗病;稳产性较好,三年的回归系数都在1.02～1.04,决定系数γ~2=0.96～0.98之间,适合于中等偏上肥力种植。但后期如遇连阴雨易穗上发芽,综合起来看还是较有希望的品种。为了做到良种良法一起推,我所于1980年开始,在中等偏上肥力条件下进行栽培试验,并对主要生物学性
Wheat germplasm fraternity 74-22 is a breeding farm in Henan Province, selected from 7023 breeding strains. In the autumn of 1978, it took the second place in the regional trial of high-fat group in our region and increased by 6.2% compared with that of the control Zheng-Yin-1. In the trial of high-fat group in 1979, 2.23% and 12.1%, ranking second, one, also ranked first in Huainan film. In the autumn of 1980, a total of 145,000 mu of cultivated area was planted in the autumn of 1981 in the autumn of 1981, and its area continued to expand in 1982. This species is semi-winter, leaves erect, medium plant height; spike, grain and grain weight; more lodging, disease resistance; stable yield better, three years regression coefficients are in the 1.02 ~ 1.04, the coefficient of determination of γ ~ 2 = 0.96 ~ 0.98 between, suitable for medium upper fertility cultivation. However, in the latter case, if the rainy spike panicle sprouting, together or look more promising species. In order to promote the good breeding method, I started cultivation experiment in mid-upper upper fertility condition in 1980,
