Abstract
The analysis of the nature and magnitude of associations among 10 quantitative traits and their contribution towardsseed yield was carried out in 30 genotypes of castor (Ricinus communis L.) during the winterseason of 2009 at Regional Agricultural Research Station, Tirupati. The results revealed that 1200 seed weight, oil yield/plant, effective length of main spike, oil content and number ofspikes/plant had significant positive association with seed yield/plant. Path analysis revealed that oil yield/plant, 100 seed weight, number of capsules on main spike, number of nodes upto main spike, plant height up to main spike and days to 50% flowering are the direct contributors for seed yield in castor.
2009年冬季，在蒂鲁帕蒂区域农业研究站对30个基因型蓖麻(Ricinus communis L.)进行了10个数量性状的关联性质、关联程度及其对种子产量的贡献进行了分析。结果表明，1200粒重、单株产油量、主穗有效长度、含油量和单株穗数与单株产油量呈显著正相关。通径分析表明，单株产油量、百粒重、主穗蒴果数、主穗以上节数、主穗以下株高和开花至50%的天数是蓖麻种子产量的直接影响因子。
