Method for obtaining plant with yellow seedlings in red pepper seedling stage

Abstract

The invention discloses a method for getting the plant with the deseription of yellow sprout in red pepper sprout stage, irradiating the red pepper seed with 60Co-gammawave ray and immersing it with HN02 solution and getting the mutant plant with the deseription of yellow sprout. The invention gets the mutant plant by means of artificial mutagenesis which irradiating the red pepper seed with 60Co-gammawave ray and immersing it with HN02 solution on the base of gaining the homozygous autocopulation system by the more than five-year continuous autocopulation of the red pepper seeds, and can distinguish the false hybrid visually in the sprout stage during the production of the first hybrid, which lays the groundwork for the production of the first hybrid of red pepper by utilizing the labeling- deseription in the sprout stage.

Description

technical field [0001] The invention belongs to the technical field of breeding, and relates to sexual hybrid breeding, utilization of heterosis, mutation breeding or breeding treatment methods such as physical and chemical mutagenesis dosage and time, especially a method for obtaining pepper plants with yellow seedling traits at the seedling stage . Background technique [0002] Capsicum is a cross-pollinated crop of Solanaceae and one of the important vegetable crops in my country. With the improvement of living standards, people constantly put forward new requirements for the quality, color, shape, flavor and supply period of peppers. Practice has proved that the first-generation pepper hybrids have significant advantages such as good quality, strong resistance, and high yield, and are welcomed by producers and consumers. [0003] Capsicum has obvious heterosis, and the use of heterosis has become an important means to increase yield and increas...

AI Technical Summary

Problems solved by technology

However, most of the first-generation hybrids of pepper that are popularized and applied in my country are produced by artificial emasculation and artificial pollination. At the same time, a series of complicated procedures such as listing marks, flower thinning, fruit thinning, and pruning are required, which not only takes time and effort, but also increases investment. Moreover, the yield of seed production is low, and false hybrids are often mixed in the harvested seeds, which reduces the seed purity of the first generation of hybrids, and false hybrids are not easy to be visually identified in the population, which seriously restricts the wide application of heterosis in pepper production.
