摘　　要：试验主要从产量、抗虫性、抗病性和纤维品质四方面详细的介绍了陕棉2365的品种特征,并研究了其产量构成特点。试验结果表明,陕棉2365棉铃经济系数、铃重、衣分、结铃性都明显优于对照美棉33B,为其高产,稳产奠定了基础。The paper studied yield component trait of Shaan 2365 from fruit retention, number of fruit branch. Lint percent, seed index, boll weight and economics index of cotton boll. The results indicate that Shaan 2365 is more than 33B in all research factors. It＇s growth Status is very well during every growth development stages, cotton-boll is bigger, lint percent is higher, flushing out is quicker, fruit abscission rate is lower. These were factors of high yield of Shaan 2365.
