| 摘 要： | 以高粱3个A2类型杂交种（A2TX622×晋粱5号、A2V4×1383-2、A2V4×晋粱5号）和3个A3类型杂交种（A3299×1174、A32457×1174、A3JW×1174）的F2群体为材料，来进行A2、A3类型高粱F2代花粉碘染色率与田间自交结实率之间关系的研究。结果表明：3个A2类型F2群体联合分析结果的回归方程为RT=1.188×R0.25＋0.906×R0.75＋0.915×R1.0，3个A3类型F2群体联合分析的回归方程为RT=0.188×R0.25＋0.832×R0.75＋0.933×R1.0，所有6个F2群体联合分析的回归方程为RT=0.193×R0.25＋0.896×R0.75＋0.949×R1.0。RT与R0.25、R0.75和R1.0之间确实存在显著或极显著的回归关系，而且品种间存在差异。

| Abstract: | The association of self-fruitful rate and rate of pollen stained with 1% I2-KI of F2 of A2 cytoplasmic male sterility（CMS） and A3 CMS in Sorghum was analyzed with F2 populations of three A2CMS cross classifications（ A2T × 622 × Jinliang 5, A2V4 × 1383-2 and A2V4 ×Jinliang5） and three A3CMS cross classifications（A3 299×1174,A3 2457 ×1174,A3JW×1174）. The regression equation of A2 CMS F2 populations was： Rr = 1.188 × R0. 25 ＋ 0. 906 × R0.75 ＋ 0. 915 × R1.0 ,and it of A3 CMS F2 populations was： Rr = 0. 188 × R0.25 ＋ 0. 832 × R0.75 ＋ 0. 933 × R1.0 . The regression equation of six F2 populations was： Rr = 0. 193 × R0.25 ＋ 0. 896 × R0.75 ＋ 0. 949 × R1.0 . There was more or the most significant liner regression between Rr and R0. 25 ,R0. 75 ,R1.0 , and it was difference in cross classifications. |
