The mutual attraction of conidia to protoperithecia of the opposite mating type was studied genetically in crosses where a mixture of conidia from two different strains, one of which was marked by an ascospore color mutant gene tan spore (ts), was applied to protoperithecia. Selective fertilization was measured as the frequency of perithecia fertilized by conidia from one strain in competition with conidia from another strain. Selective fertilization by a given strain varied throughout the range from 10 to 97% according to the strains of protoperithecial parent. The selective fertilization was revealed to be under the control of two or more loci, which appeared to have multiplicative action. No indication of a cytoplasmic effect on selective fertilization was obtained. The strength of the mutual attraction between conidia and protoperithecia decreased as genetic similarity increased.
在杂交实验中，对分生孢子与相反交配型原囊壳之间的相互吸引力进行了遗传学研究。将来自两个不同菌株的分生孢子混合体（其中一个菌株由子囊孢子颜色突变基因棕孢子（ts）标记）施用于原囊壳。选择性受精以一个菌株的分生孢子在与另一个菌株的分生孢子竞争中使子囊壳受精的频率来衡量。根据原囊壳亲本的菌株不同，特定菌株的选择性受精在10%至97%的范围内变化。结果表明，选择性受精受两个或更多位点的控制，这些位点似乎具有相乘作用。未获得细胞质对选择性受精有影响的迹象。分生孢子与原囊壳之间相互吸引力的强度随着遗传相似性的增加而降低。
