利用一代杂种以提高番茄的产量,是近代许多科学研究工作者为之努力的一个目标。今天,一代杂种番茄已在许多国家广泛用于生产。现住的问题不在于番茄有没有杂种优势以及能不能利用这种杂种伏势,达些都住理论上和实践中作出了肯定的回答。现在的问题是,怎样才能获得更大的杂种产量伏势?这当然不是一个简单的问题,它包括许多复杂的甚至是可变的因素。从育种的角度来说,最重要的是达样三个因素,即:1、一代杂种番茄有没有高度的适应性,特别是有没有高度的抗病性和抗逆性,没有高度的适应性就不可能保证高产组合表现其高产性能;2、一代杂种番茄能不能提供足够多的光合剩余产物供貯存器官(果实)貯 Utilizing a new generation of hybrids to increase the yield of tomato is a goal that many modern scientific researchers worked hard on. Today, a generation of hybrid tomatoes has been widely used in production in many countries. The problem is not living in tomato hybrids have heterosis and can not use this hybrid potential, to live and live in both theory and practice made a positive answer. The question now is, how can we get more potential for hybrid production? This is certainly not a simple problem, and it includes many complex and even variable factors. From the breeding point of view, the most important thing is to sample three factors, namely: 1, a generation of hybrid tomatoes have a high degree of adaptability, in particular, is there a high degree of disease resistance and resistance, there is no high degree of adaptability It is impossible to ensure that high-yield combinations will show their high-yielding performance.2. The first-generation hybrid tomato can not provide enough photosynthetic residuals for storage (fruit)
