高产品种陕棉6192皮棉产量增产分析

Analysis on Increasing Yield Characters of a New Cotton Cultivar Shaan 6192

通过对陕西省棉花品种区域试验、棉花品种生产试验及大面积推广情况的调查研究表明。陕棉6192衣分较高为45％,单株结铃性较强,单株皮棉较多,皮棉产量高于对照中棉12为3.4％～37.94％;陕棉6192烂铃率、僵瓣率均较低,具有耐阴雨,抗烂铃特性;根系较深且发达,大旱之年不减产;因此,不同年份、不同气候、不同地区均能增产、稳产。

The Shaanxi cotton variety regional tests ,Shaanxi cotton production test and large area popularization were analysed.The results showed that lint percentage of Shaan 6192 was 45%,boil numbers plant and lint yield plant of Shaan 6192 were the best,lint yield of Shaan 6192 was 3. 4-37. 94% higher than CK Zhong 12,rotten bolls and stiff section percentage of Shaan 6192 were lower than CK Zhong 12. So Shaan 6192 had characters of resistant rotten bolls. The roots of Shaan 6192 were developed, and there was not reduced yield in great drought years. So Shaan 6192 was increasing and stable yield variety in the different years,climates and regions.
