摘要
对6个棉花推广品种两年多点试验的资料进行产量联合方差分析、稳定性评估和各品种产量差异的生物学原因分析表明,泗棉2号为高产稳产、适应性广的品种,具有根系活力较强、主茎生长稳健、叶面积消长合理、光合强度大、吐絮高峰期长、花铃期生殖生长与营养生长有较高水平的协调等优点,是我省滨湖棉区、澧阳平原棉区和湘中分散棉区最适宜推广的品种(重病田例外);湘棉10号适于病区推广;4108和32系可考虑更换品种。
Six popularized cotton varieties were tested in many locations in 2 years.The results showed that Simian 2 is a high and stable-yielded variety with widespread adaptability,vigorous root system,stable growth of main stem,reasonable increase and decrease of leaf area,higher light intensity,long time of peak boll-opening,as well as the a reasonable coordination between reproductive and vegetative growth at flowering stage,that is best suitable for popularizing in the cotton regiens of Hunan Province (except the seriously disease infected field).
