摘 要: | [目的]探索杂交棉新陆早70号F_1、F_2代纤维品质之间的差异性,为新陆早70号F_2代的推广应用提供依据和参考。[方法]以自育早熟杂交棉新陆早70号为试验材料,通过田间小区试验,研究其F_1、F_2代不同果枝层位的纤维品质表现。[结果]新陆早70号F_1、F_2代不同果枝层位的棉纤维均以棉株中部4~6层第1果枝节位纤维品质最优。在各个组内、组间F_1、F_2代纤维品质差异表现均不显著。[结论]若仅从纤维品质角度考虑,在大田生产上推广种植新陆早70号的F_2代还是可行的。

Abstract: | Objective] To explore the difference between hybrid cotton Xinluzao 70 F1 and F2 , to provide basis and reference for extension and application of Xinluzao 70 F2.[Methods] Early mature hybrid cotton Xinluzao 70 was taken as experimental material.Field block experi-ment was carried to study fiber quality of different fruiting layers of Xinluzao 70 F1 and F2 .[ Results] For cotton fiber of different fruiting layers of Xinluzao 70 F1 and F2 , the fourth to sixth layers of the first fruiting branches have the best quality.In each group, the difference between Xinluzao 70 F1 and F2is not significant.[ Conclusion] Only from the perspective of fiber quality ,it is feasible to extend Xinluzao 70 F 2 gener-ation in field production. |
