棉花纤维素沉积特性的遗传分析

GENETIC ANALYSIS ON CELLULOSE DEPOSITION OF COTTON FIBER

本研究利用~3H标记,对陆地棉(Goossypium hirsuturn L.)和海岛棉(Goossypiumbarbardense L.)不同品种及海岛棉×陆地棉杂种F_1代的纤维素沉积特性进行了分析。结果表明,与亲本比较,杂种F_1明显改善了纤维素沉积状况,沉积峰期较陆地棉明显后移,尤以前期纤维素沉积较快的品种,如鲁棉二号与海岛棉杂交后,纤维素沉积状况较陆地棉亲本改善更大。

By using 3H-labelling techniques the cellulose depositions of upland cotton (G.hirsutum),sea island cotton (G.barbadende) and their F1 hybrides were determined.It was found that in F1 the cellulose deposition model was improved significantly compared with that of parents.The period of the highest speed of cellulose deposition in F1 was later than that of parents of upland cotton.
