徐州地区春萝卜品种种植表现及其性状分析

选择3个春萝卜品种在徐州地区种植,对其种植表现进行评价,并对其相关性状进行统计分析.试验结果表明,春萝卜新品种南春白5号、6号生长势旺盛,极耐抽薹,无糠心现象,商品性好,适宜在徐州地区种植,可进一步推广.相关分析表明,单根质量与小区产量极显著相关,是构成小区产量的重要因素;根长、根粗与小区产量显著相关,相关系数均达到0.96;根长与单根质量显著相关,相关系数达0.98,进一步说明根长的增加能够促进单根质量的增加.

Planting Performance of Spring Radish and Correlation Analysis on Their Main Agronomic Characters in Xuzhou Area

Three spring radish cultivars were selected to plant in Xuzhou area, and their planting performance and correlation analysis of their main agronomic characters were studied. The results showed that the two new spring radish cultivars Nanchunbai No.5 and Nanchunbai No.6 had the excellent characters of strong growth vigor, tolerance to bolting and hollowness and good commercial quality, and they were suitable for planting in Xuzhou. The results of correlation analysis showed that, the single root weight was very significantly correlated with the plot yield, and it was the important component for radish plot yield. The root length and root diameter were significantly correlated with the plot yield, with the correlation coefficient of 0.96. and the root length was also significantly correlated with the single root weight, with the correlation coefficient of 0.98, which further indicated that the increase of radish root length promoted the single root weight.
