Method for producing hot pepper hybrid and purity identification method

Abstract

The invention discloses a method for producing a hot pepper hybrid and a purity identification method, and belongs to the field of hybrid hot pepper seed production. The method for producing a hot pepper hybrid is characterized in that a hot pepper variety with styles of dominant character color is used as a male parent, and a hot pepper variety with styles of recessive character color is used asa female parent for hybrid seed production; the style color of the male hot pepper variety is purple; the style color of the female hot pepper variety is white; the hot pepper variety with purple styles is 8214 purple or J0721 purple; both indoor planting and field planting can be carried out; the identification time is shortened, fruit setting and bud unfolding are not needed for identification,the hybrid purity identification result is reliable, rapid and accurate, and the purity identification period only needs about 30 days; the identification cost is decreased by higher than 80%; and theproblems of large error, long time and high cost in purity identification of hybrid hot pepper at the present are solved.

Description

technical field [0001] The invention relates to the technical field of hybrid capsicum seed production, in particular to a production method and a purity identification method of a capsicum hybrid. Background technique [0002] Hybrid peppers play a very important role in the production and supply of vegetables in my country. At present, the method of manual removal of pollination is mainly used in the production of hybrid pepper seeds, and the method of artificial emasculation and pollination is used to produce hybrids. Thorough and untimely waiting to produce fake hybrids can easily cause economic losses. [0003] At present, the main method for identifying the purity of hybrid pepper seeds is field identification. Plant the sample seeds of the hybrid seeds in the field, observe the agronomic traits of the plants, such as fruit, plant height, plant width, leaf shape, etc., if the traits are consistent with F1, then judge For F1 hybrids, this method is the most widely used....

Problems solved by technology

The cotyledon purple trait in the present invention is genetically stable, and its performance is not affected by climate, cultivation conditions, etc., so that the pseudo hybrid can be stably identified from the hybrid population when the cotyledon is unfolded, and the hybrid purity identification result is reliable, fast and accurate. The purity identification period only needs about 10 days, and the purity identification cost is reduced by 90%; the false hybrids with normal green cotyledons can also be pulled out at the seedling stage in production, reducing the economic loss caused by the purity of the hybrids; but there are still certain defects. The use of cotyledons for production and identification is generally only applicable to the pepper variety 9004 purple with purple cotyledons, and the seedling marker traits with purple cotyledons can only be used within the scope of this variety and cannot be widely promoted
