摘要
以 2 4种不同山羊草细胞质的稳定同核异质杂种为材料 ,进行了植株生长特性、病害抗性、抗低温能力、光合特性、主要农艺性状、自交育性和种子蛋白质含量等方面的比较研究。同时 ,还分析了异源细胞质效应的遗传特点 。
A series of experiments were carried out using stable homouncleo alloplasmic hybrids with cytoplasms of 24 Aegilops species. The cytoplasmic effects of each hybrid were studied which included growth habits, disease resistance, low temperature tolerance, photosynthetic characteristics, major agronomic traits, self fertility and seed protein content. All of the traits mentioned above were compared with those of spring wheat. The genetic characteristic of cytoplasmic effects were analysed and the valuable materials in utilization of nucleo cytoplasmic heterosis for agricultural production were suggested.
