辣椒在我国的种植面积仅次于白菜位居第二,而产值和效益雄踞蔬菜作物之首。近年来,越来越多的育种单位加入到了辣椒育种的行列。而随着我国劳动力成本的增长,辣椒制种成本也愈来愈高,再加上繁种市场的不规范,亲本流失情况越来越严重,越来越多的单位开始研究辣椒三系杂交制种技术,来保护亲本,降低制种成本。1.三系杂交的概念所谓三系,是指配制一个优良杂交种所需要的特定的三个系,包括雄性不育系、雄性保持系和雄性恢复系,三系必须配套才能使用,缺 Pepper planting area in China is second only to cabbage, while the output value and effectiveness ranked first in vegetable crops. In recent years, more and more breeding units have joined the ranks of pepper breeding. With the increase of labor cost in our country, the cost of seed production is getting higher and higher. Besides, due to the non-standard breeding market, the loss of parents is more and more serious. More and more units begin to study the three-line hybrid system Kind of technology, to protect the parents, reduce the cost of seed production. 1. The concept of three-line hybrid The so-called three-line, refers to the preparation of a good cross hybrids required for the three specific lines, including male sterile lines, male and male restorer lines Department, three lines must be used to support the lack of
