绿叶菜,尤其是青菜深受上海市民喜爱,需求量大。受夏季高温影响,常造成绿叶菜供应不足。因此,开展绿叶菜耐热性遗传改良,从种性上提高绿叶菜的耐热性显得十分重要。由于绿叶菜现有品种中缺乏耐热性较强的材料,很难通过常规育种手段达到选育高耐热品种目的。大量研究表明:植物的耐热性属于多基因协同控制的性状,当然其中不乏存
Green leafy vegetables, especially vegetables by Shanghai people love, demand. Affected by the summer heat, often caused by lack of supply of green leafy vegetables. Therefore, it is very important to carry out the genetic improvement of the heat tolerance of green leafy vegetables and to improve the heat resistance of the green leafy vegetables. Due to the lack of heat-resistant materials in the existing varieties of green leafy vegetables, it is difficult to achieve the purpose of breeding high heat-resistant varieties by conventional breeding methods. Numerous studies have shown that: plant heat tolerance is a multi-gene synergistic control of the traits, of course, there is no shortage of them
