Abstract

Two sweet-waxy corn inbred lines, Jikenuo 20 and Wannuo 2000, were used as experimental materials. A randomized block experiment was conducted to analyze the differences and similarities in plant traits, ear traits, yield, appearance quality and main cooking quality between the two sweet-waxy corn varieties. Results showed that there were no significant differences in most plant traits, ear traits and yield between the two sweet-waxy corn varieties, indicating that the inheritance of the nucleus was dominant. There were some differences in the resistance and some cooking quality of the two sweet-waxy corn varieties in the reciprocal cross combinations, which indicated that the above characters were affected by cytoplasmic inheritance to a certain extent.

正交对两种甜糯玉米主要性状及产量的影响品种
以2个甜糯玉米自交系吉可诺20号和万诺2000为试验材料。采用随机区组试验,分析两个甜糯玉米品种在植株性状、穗部性状、产量、外观品质和主要蒸煮品质等方面的异同。结果表明,两个甜糯玉米品种在大部分植株性状、穗部性状和产量上均无显著差异,表明以核遗传为主。在正交组合中,两个甜糯玉米品种的抗性和部分蒸煮品质存在一定差异,说明上述性状在一定程度上受到细胞质遗传的影响。[j] .植物学报,52(2):625- 630,2023(6):特刊
