摘要
以13个不同来源糯玉米自交系为材料,采用不完全双列杂交法,分析糯玉米株高、穗位高、穗长、穗粗、穗行数、行粒数和籽粒产量的遗传规律。结果表明:穗行数、秃尖、行粒数、穗粗和籽粒产量的遗传主要是加性效应,而株高、穗位高、穗长的遗传更易受环境因素的影响。综合性状表现较好的是NB 195,其次是NB 241、NB 228和NB 248。
By taking incomplete hybridization in-line method, the inheritance of plant height, ear height, ear length, ear thickness, row number per ear, grain number per row and grain yield were analyzed with 13 waxy maize inbred lines with different resources were used as materials. The results showed that the inheritance of row number per ear, bald length, grain number per row, ear thickness and grain yield was additive while that of plant height, ear height and ear length were easily affected by environmental factors. The best performance of integrated characteristics was NB195, and then NB241, NB228 and NB248, respectively.
