通过对10对陆海杂种一代的优势表现研究,表明陆海杂种的产量、籽指、铃重、铃数、株高、果枝数、果节数和纤维品质均具有明显的中亲优势,与双亲的平均值比较,籽棉产量高出22 32%,皮棉产量高出7 25%,铃重增加5 36%,成铃数增加33 21%,株高增加30 04%,果节数增加26 68%,陆海杂种结铃性较好,结铃数与对照相比,增加19 50%,而铃重和衣分较对照,平均下降16 59%和23 81%。纤维品质优势明显,2 5%跨长、比强度、伸长率、麦克隆值的平均竞争优势均在30%以上,整齐度增幅较小,平均为5 17%;多数组合的2 5%跨长大于34mm,比强度大于35cN/tex,麦克隆值在3 7~4 2的A级范围内。表现出超高亲遗传。
Through the study on the dominant performance of 10 pairs of land-sea hybrids, it showed that the yield, seed index, boll weight, boll number, plant height, number of fruit branches, fruit number and fiber quality of land and sea hybrids all had obvious mid- The average of parents was 22 22% higher than seed cotton, 7 25% higher lint yield, 536% boll weight, 33 21% boll number, 30 04% plant height and 26 68 fruit section %, And the land-sea hybrids had better boll-forming ability. The number of bolls was 1950% higher than that of the control, while the boll weight and the clothes were decreased by 16 59% and 23 81% on average. The average competitive advantage of specific strength, elongation and micronaire were more than 30%, with a slight increase of uniformity, with an average of 5 17%. The majority of the combinations of 25% across Grow more than 34mm, the specific strength is greater than 35cN / tex, the micronaire value in the range of 37 ~ 42 A level. Show super high progenitor.
