平菇属糙皮侧耳、美味侧耳、白黄侧耳，与佛罗里达侧耳是同一可交配群体。选用该群体７个亲株的１４个单核株按半轮配方式配成９１个组合，其中１２个为不亲和组合，总亲和率为８６８１％。该群体的性因子基因型达１１对之多（Ａ１Ｂ１～Ａ１１Ｂ１１）；栽培其中７６个亲和组合及７个亲株，对其生物效率进行方差分析，结果显示处理间存在极显著差异（Ｆ＝１２．７９１５），前１０名杂交种的超亲优势为１５．６９％～１１５．７５％。同时对半轮配９１个配对组合的一般配合力（ｇｃａ）与特殊配合力（ｓｃａ）进行分析，配对组合间，ｇｃａ效应与ｓｃａ效应值间也存在着真实差异。单核株Ｄ１的ｇｃａ＝２４．２７，为最高，其次是Ｏ８、Ｄ４、Ｏ７、Ｌ１０，说明这几个单核株在以产量为指标的杂交育种中，有良好的基因加性效应。ｓｃａ效应分析显示，Ｄ４Ｌ１０的ｓｃａ＝６３．９９，为最高。对同一单核株不同组合的ｓｃａ值进行显著性测定，结果显示Ｄ４、Ｌ１０可产生较强的杂种优势，Ｄ１产生的优势效应居中，而Ｏ７、Ｏ８较次。本文还对平菇杂交育种过程中的配合力与配对亲和性进行了讨论。
Pleurotus genus Pleurotus ostreatus, delicious ear, white-bellied ear, and Florida ear is the same can be copulatory groups. A total of 14 mononuclear strains of 7 progeny from this group were grouped into 91 combinations according to the half round formula, of which 12 were incompatible and their total affinities were 8681%. There were 11 pairs of genotypes (A1B1-A11B11) in this population. Among them, 76 combinations and 7 progenies were cultivated, and their biological efficiency was analyzed by ANOVA. The results showed that there were significant differences (F = 12.7915). The top 10 heterosis of the top 10 hybrids ranged from 15.69% to 115.75%. At the same time, we analyzed the general combining ability (gca) and special combining ability (sca) of 91 mating combinations of half rounds. There was also a true difference between the pair combination combinations, gca effect and sca effect value. Monoclonal strain D1 gca = 24.27, the highest, followed by O8, D4, O7, L10, indicating that these mononuclear strains in the yield as an indicator of cross breeding, have a good gene additive effect. sca effect analysis showed that the sca of D4L10 was 63.99, which was the highest. The sca values of different combinations of the same mononuclear strains were significantly determined. The results showed that D4 and L10 could produce stronger heterosis. The dominant effect of D1 was middle while O7 and O8 were less. The paper also discussed the combining ability and matching affinity of the crossbreeding of Pleurotus ostreatus.
