对棉花三系杂种第一代的研究

A Study on Hybrids F_1 of Three Lines in Cotton

１９９４年对２０个棉花三系杂种Ｆ１进行了比较试验，对照品种为新陆早１号。结果表明：参试杂种Ｆ１中有７个杂种皮棉产量高于新陆早１号，其中中Ａ×４Ｒ－２２产量最高，比对照增产１５％，但未达显著水平。在产量组成因素及纤维品质指标上有不少杂种Ｆ１却明显优于对照，达显著或极显著水平；特别在铃重和绒长方面表现尤为突出。

In 1994,twenty cotton hybrids F1 of three lines and Xinluzao No. 1 as chech were tested in the experimental field and room. The results showed that seven hybrids were better than check for lint yield. Among them Zhong A × 4R - 22 was the best,its lint yield was higher than check by 15%, but the difference was Non-Significant. However, the significant difference better than check were found for yield components and fiber quality traits,such as boil size, lint percentage, fiber length and elongation. Clearly, the potential of these hybrids for increasing lint yield and improvement of fiber quatity is very strong to the cotton production.
