早熟棉品系在北疆和晋南的适应性分析
Adaptability Analysis of Early Maturing Cotton Lines Planted in Northern Xinjiang and Southern Shanxi
摘要
Abstract
In order to clarify the growth and development characteristics of early maturing cotton lines in two different ecological conditions of northern Xinjiang and southern Shanxi,in this study,identification tests of 13 early maturing cotton lines were set up in the two ecological regions for two years,providing reference for cotton variety introduction test in the two places.The results showed that the growth period of 13 early maturing cotton lines was 118-128 days in northern Xinjiang and 109.5-135 days in southern Shanxi.In northern Xinjiang,the plants of each line were shorter and the average number of fruit branches was 9.1.In the south of Shanxi,it was tall and loose,late maturing,and the average number of fruit branches was 13.1.The number of bolls per plant in southern Shanxi was also more than that in northern Xinjiang.The boll weight and lint percentage of early maturing cotton lines had little difference between the two places,the yield was high in northern Xinjiang with lint yield of 1290 to 2 572.5 kg/ha,and it was 354 to 1 005 kg/ha in southern Shanxi.The fiber length,uniformity,and specific strength of all lines were basically the same in the two places.The micronaire value was better in northern Xinjiang,ranging from 3.55 to 4.65,in the range of A level,while in southern Shanxi,it was 3.96 to 5.69,in the B2 range.The adaptability of the early maturing cotton lines in northern Xinjiang and southern Shanxi was different,but the adaptability analysis ranking of five varieties including Jinzao 1,Jinzao 2,Jinzao 8,Jinzao 4,and Jinzao 11 were at the top in the two places,indicating that these five early maturing cotton lines could be planted in both of northern Xinjiang and southern Shanxi.关键词
