以玉米自交系８１１２植株为试验基础材料，取其套袋自交授粉后的幼胚离体进行组织培养，将所得到的愈伤组织再生植株后代不同株系问的产量配合力进行了初步探讨分析。结果表明，来源于同一基础材料的再生植株后代不同株系间的产量配合力有明显的差异，其中能出现配合力较高的株系、利用体细胞无性系变异选育高配合力的自交系是玉米育种的一条新途径。
The maize inbred line 8112 was used as the experimental material, and the immature embryos after self-pollination by bagging were isolated and cultured in vitro. The yield combining ability of the obtained callus regenerated plants from different lines was preliminarily studied Explore and analyze. The results showed that there were significant differences in the yield combining ability among the regenerated plants derived from the same basic material, among which the higher combining ability lines could emerge, the somatic clonal variation could be used to breed the inbreds with high combining ability Department of maize breeding is a new way.
