抗草甘膦杂交棉F_2代利用价值研究

Studies on Utilization Values of F_2 Hybrid Vigor in Roundup-ready Cotton

通过对8个抗草甘膦杂交棉F2代进行多个性状的比较,从结铃性、农艺性状、抗性、产量、纤维品质等方面进行分析。结果表明:各杂交组合F2代均表现出较高的抗草甘膦性能和纤维品质指标优于对照。1、6号材料的F2代,抗草甘膦、高产、优质,综合性状优良,且制种成本低,有较高的利用价值。

8 F2 hybrids of roundup-ready cotton compare test were carried out multiple characters,the characters included the bolls per plant,agronomic traits,resistance,yield,fiber quality etc.were analyzed.The F2 generation of hybrid combinations showed high resistance to glyphosate resistance;Two combinations of F2 generation hybrid seed cotton yield were higher than the cotrol,but the increase was not significant.The fiber quality of all crosses of the F2 generation were better than the control.The results showed that F2 generation hybrid combination 1 and combination 6 were glyphosate-resistant,high yield,high-qualityo,exhibited excellent general characters and cotton seed reproduction in lower cost,so they had higher utilization values in cotton production.
