A kind of breeding method of oily type cucumber female line

Abstract

The invention discloses a breeding method of a glossy cucumber female line. The method comprises the following steps: hybridizing the glossy cucumber germ plasm with female-line cucumber germ plasm to obtain a generation 1; performing backcrossing by taking the glossy cucumber germ plasm as a recurrent parent to obtain backcrossed 1st-generation seeds, namely a generation 2; in a generation 3, selecting male inducing sister cross in a nursery separation way for polymerization of glossy character and female character, and selecting and remaining seeds; and after that, performing male inducing selfing, purifying the glossy female line in an obvious nursery and a seed selection nursery, and performing selfing of 2-3 generations to obtain the glossy cucumber female line. According to the invention, in the generation 3, through the male inducing sister cross in a nursery separation way, the contradiction between the seed selection and the seed remaining through the polymerization of glossy character and female character is effectively solved; and moreover, the early generation effectively maintains more excellent genes to facilitate later selection of a selfing system with good comprehensive characters.

Description

technical field [0001] The invention relates to the technical field of breeding methods, in particular to a breeding method for oily cucumber female lines. Background technique [0002] Cucumber is one of the important vegetable crops in China, and its output and output value are in the forefront of vegetable crops. At present, cucumbers have been cultivated all year round, which plays an important role in the balanced supply of vegetables. High quality and high yield of cucumber is an important goal of breeding. The appearance quality traits of cucumber, such as the glossiness of the skin color, are important traits that determine the marketability of cucumbers, and the female traits are important constituent traits that affect the high-yield potential of cucumbers. Traditional cucumber varieties are affected by genetics and the environment. The surface of the fruit is covered with wax powder, which is dull and dull, which affects its sales. In recent years, the use of w...
