| 摘 要： | 燕麦的抽穗前天数及灌浆持续期是和生育期密切相关的两个性状。本文通过５个亲本双列杂交的１０个Ｆ＿１［１／２ｐ（ｐ－１）］对它们的配合力进行分析，结果表明，两性状的一般及特殊配合力方差均达显著或极显著水平，当一个亲本（或组合）在抽穗前天数上有较高配合力时，其灌浆持续期的配合力就相应较低。

| Abstract: | Both days to heading and grain- filling period were highly correlated with daysto maturity in Oats(A. sativa L. ). In this paper, 10 F_1 hybrids[1/2p(p-1)]derived from thediallel cross of 5 parents were used to analyse the combining abilitis of two characters. Theresults showed that the variances of general combining ability(g.c.a.)and specific combiningability(s.c.a. )were significantly different,and a parent(or cross)with a high combining abil-ity value in days,to heading often had a low combining ability value in grain-filling period. |
