宿育1号品种是我所于1976年以郑州741为母本、扬麦2号为父本,经有性杂交和系谱法选育,于1981年育成。原名“皖宿8112”。经多年多点试验、示范,表现高产、稳产,尤其具有晚播早熟的特点,为群众所喜爱。1984～1985、1987～1988年度,我所小麦室分别对该品种进行了播期、密度裂区试验,以期对大面积生产应用有所裨益。一、试验设计和方法两年密度试验每亩基本苗均为15、20、25、30、40万,播期1984～1985年度为10月20、25、30日、11月4、16、24日;1987～1988年度以10月20日为基数,10天为一级差,均为六个播期,并以播期为主区,密度为 The first variety of Suyu 1 was bred in 1981 with Zhengzhou 741 as female parent and Yangmai 2 as male parent in 1976 by sexual cross and pedigree selection. Formerly known as “Wan Su 8112”. After many years of trial, demonstration, performance of high yield, stable yield, especially with the characteristics of early sowing premature, loved by the masses. From 1984 to 1985 and from 1987 to 1988, we conducted the sowing and density cracking tests on this variety in our wheat room, in the hope of benefiting large-scale production and application. First, the experimental design and methods Two years of density test of basic seedlings per acre are 15,20,25,30,40 million, sowing period of 1984 to 1985 for October 20, 25,30, November 4,16,24 Day; from 1987 to 1988 on October 20 as the base, 10 days for the first grade, are six sowing date, and sowing-based area, the density of
