胭脂萝卜主要农艺性状对肉质根产量的影响

Effect of Main Agronomic Character on Yield of Fleshy Root in Rouge Radish

以8个胭脂萝卜品种为试材,采用回归和通径分析方法分析了主要农艺性状对肉质根产量的影响。结果表明,株高、开展度、叶鲜质量、根外露长和根皮厚对肉质根产量影响显著,其中根外露长对肉质根产量作用最大,直接通径系数为1.021 3,其余性状依次为根皮厚、株高、叶鲜质量、开展度。高产育种应在提高根外露长的基础上,选择株形较大或根皮较厚的品种。

8 rouge radish varieties were used to analyze the effect of main agronomic character on yield of fleshy root with regression and path analysis .The results showed that plant height ,sprea-ding degree ,leaf fresh weight ,outside root length and peel thickness had significant effect on yield of fleshy root ,and the order was outside root length ,peel thickness ,plant height ,leaf fresh weight and spreading degree .The larger radish and radism with thicker peel of fleshy root on the basis of improved outside root length should be selected for high-yield breeding .
