稳产性是一些作物育种程序的目标。实际上,植物育种者关心的是在不良环境条件下产量的表现。耐瘠薄和干旱问题与稳产有关。不同高粱杂交种对干旱和高温的反应存在着变异。在某种不良环境条件经常发生的地区,具有较强的耐不良环境的基因型更为稳产。因 Stability is the goal of some crop breeding programs. In fact, plant breeders are concerned with the performance of yields under adverse environmental conditions. Barren and drought-resistant issues are related to stable production. There are variations in the responses of different sorghum hybrids to drought and high temperatures. In some areas where adverse environmental conditions occur frequently, the genotypes with stronger resistance to adverse environment are more stable. because
