摘　　要：以"雪单一号"萝卜为试材,研究了萝卜主要农艺性状与肉质根产量的相关性。结果表明:根长、外露长、叶片数、株高与肉质根产量之间呈显著正相关,而根粗、叶片长、叶片宽与肉质根产量之间呈较弱负相关;各个性状对萝卜单株肉质根产量的总效应由大到小依次是株高>根长>外露长>叶片数>叶重>展开度>叶片长>根粗>叶片宽。因此,在选育萝卜品种和制定萝卜高产栽培措施时,应在稳定萝卜根部性状的基础上,提高萝卜叶面积,达到高产稳产。Taking radish variety ＇Xuedan No.1＇ as material,the correlation of the major agronomic characters of radish and fleshy root yield were studied.The results showed that the root length,outside root length,angular divergence,leaf number,plant height and the fleshy root yield had obvious positive correlation.The root width,leaf length,leaf width and the yield had weak negative correlation.The total effect of every major character and yield was ranked as following：plant heightroot lengthoutside root lengthleaf numberleaf weightangular divergenceleaf lengthroot widthleaf width.Therefore,when selecting the variety and making out high yield for radish,the leaf area should be increased to improve the yield on the base of stabilizing.
