【摘要】 对高油酸花生品种‘开农308’的11个农艺性状进行了产量构成的相关分析，结果表明，各性状的变异系数在2.95%～30.53%之间，出米率的变异系数最低为2.95%，单株结果数、单株生产力、总分枝数、结果枝数、百仁重、百果重、主茎高、侧枝长、荚果产量等变异系数均在10%以上。出米率、百仁重、百果重等3个性状与产量呈显著正相关，主茎高与侧枝长、百果重与百仁重、单株结果数与饱果率、百仁重与出米率、百果重与出米率呈极显著正相关。百仁重、结果枝数、单株结果数对产量的直接通径系数虽为负值，但是其通过其他性状产生了较高的间接效应，最终与产量呈正相关。因此，在花生育种中，应综合考虑这些因素，协调好性状间的关系。更多还原

【Abstract】 The correlation analysis of yield composition of 11 agronomic characters of peanut variety ’Kainong308’ with high oleic acid was carried out. The results showed that the coefficient of variation of each character ranged from 2.95% to 30.53%, the lowest coefficient of variation of peanut kernel yield was 2.95%, and the variation coefficients of fruit number per plant, productivity per plant, total branch number, fruiting branch number,hundred kernel weight, hundred fruit weight, main stem height, branch length and pod yield were all above 10%.The peanut kernel yield, hundred kernel weight and hundred fruit weight were positively correlated with the yield.There were significant positive correlations between main stem height and lateral branch length, hundred fruit weight and hundred kernel weight, fruit number per plant and satiety rate, hundred kernel weight and peanut kernel yield, hundred fruit weight and peanut kernel yield. Although the direct path coefficient of hundred kernel weight,number of fruit branches and number of fruit per plant on yield is negative, it has a higher indirect effect through other traits, and finally has a positive correlation with yield. Therefore, these factors should be considered comprehensively in peanut breeding to coordinate the relationship between characters.更多还原
