Breed conservation method of dark purple pepper germplasm resource

Abstract

The invention discloses a breed conservation method of a dark purple pepper germplasm resource, and belongs to the technical field of plant breeding. The method comprises the steps that during a seal leaf period, a seeded and emerged dark purple pepper material is weeded, and plants with non-purple sead leaves in a colony are removed; during a main leaf period, plants with pallescent purple main leaves in the colony are removed, and plants with dark purple leaves are reserved for seed reserving and breeding; before blooming, each single plant is covered with a nylon fly net bag, so that selfing is firm and seeds are harvested; and then the steps are circulated year after year. The germplasm characteristics can be kept constant continuously, and the method can be utilized sustainably.

Description

technical field [0001] The invention relates to a seed preservation method of concentrated purple pepper germplasm resources, which belongs to the field of plant breeding, and more specifically relates to a technique for preserving the germplasm of peppers with concentrated purple genes by combining seedling selection and bagging techniques. Background technique [0002] Thick purple pepper is a rare germplasm resource of pepper. Not only is the fruit rich in nutrition, but its leaves can also be used to extract anthocyanins. The germplasm resources of thick purple pepper can be used as the parents of new varieties of purple pepper, which is very precious. Since peppers are often cross-pollinated plants, often due to the action of wind and more mainly insects, outcrossing with non-purple peppers occurs and changes their original species. Therefore, special measures must be taken for this type of pepper. germplasm resources are protected. At present, the preservation of the...

Problems solved by technology

At present, the preservation of thick purple pepper germplasm still adopts the traditional method of identification of seedlings, artificial pollination and self-crossing, which is extremely time-consuming and labor-intensive.
