一、选育经过赣棉78—7系我所1975年用徐州142为母本,与辽宁3号杂交,经F_2代圃株选和南繁加代,于1978年F_4代参加品系预备试验,1979年定名为“赣棉78—7”。1980年为F_6代。现各种性状巳基本稳定,正在我省参加区域化鉴定,1981年并选拔参加了长江流域耕作改制棉花新品种区域试验。二、产量表现1978年在所内新品系预试圃中,折合亩产皮棉147.03斤,比对照种(沪棉204原种,下同)增产18.29%,居全试验20个品系的第三位。1979年在所内两个新品系比较试验中,(4/10及4/11播种),亩产皮棉为153.44斤及160.67斤,分别比对照种增产6.8%及
First, breeding after Gan cotton 78-7 Department of our 1975 with Xuzhou 142 as the female parent, and Liaoning No. 3 hybrids, the F 2 generation nursery strain selection and the South Fangen generation, in 1978, F_4 generations to participate in the preparation of test strains, 1979 Year named “Gan cotton 78-7.” 1980 F_6 generation. Now that the traits have been basically stable, is in our province to participate in the identification of regionalization, and in 1981 and selected to participate in the tillage and reform of cotton varieties in the Yangtze River Basin regional trials. Second, the production performance In 1978 in the new line of pre-test nursery, equivalent to 147.03 kg per mu of lint, than the control species (Shanghai cotton 204 species, the same) an increase of 18.29%, ranking the third test of 20 strains. In 1979, the two new lines within the trial, (4/10 and 4/11 sowing), lint yield was 153.44 pounds and 160.67 kg, respectively, an increase of 6.8% over the control and
