苏棉1号原系号5122,是最近由江苏省农作物品种审定委员会审定通过的抗枯萎病棉花新品种。该品种具有高抗枯萎病、早熟、稳产、高产、纤维品质好等优点。 一、选育经过 1974年以岱红岱与岱字棉16号杂交,並南繁加代,1977年从中获得株型比较理想的新品系1087-2。该品系主要特点是株型疏朗,果枝较直,果枝与主茎的夹角较小,群体透光性好,结铃性强。为了改进其早熟性,並引进抗枯萎病种质,1977年以1087-2与黑山棉1号进行杂交,1978年再以86-1与1087-2×黑山棉1号的F_1进行复式杂交,1980年从其后代中选得一批株型、早熟性及抗病性均比较理想的株系,经1981年及1982年连续两年品系比较,从中评选出优系5122(即苏棉1号)。
Su cotton 1, the original line number 5122, is recently approved by the Jiangsu Provincial Crop Variety Approval Committee approved a new wilt resistance cotton varieties. The variety has high resistance to blight, early maturity, stable yield, high yield, good fiber quality and so on. First, the breeding After Dai Dai Dai and Dai Zi No. 16 cotton hybrid in 1974, and the South Fanucai generation, in 1977 to obtain a more ideal plant line new line 1087-2. The main characteristics of the strain is the type of plants scattered, fruiting branches more straight, the smaller the angle between the fruiting branches and the main stem, translucent group is good, strong bell ring. In order to improve its precocity and introduce germplasm with resistance to Fusarium wilt, the hybridization was carried out with 1087-2 and Heishanmian 1 in 1977 and the F_1 with 86-1 and 1087-2 × Heishanmian 1 in 1978. In 1980, a batch of strains with perfect plant type, early maturity and disease resistance were selected from their descendants. Based on the two consecutive years of 1981 and 1982, the best line of 5122 (ie SuMian 1) .
