Method for selecting early-maturing yellow skin pepper germplasm

Abstract

The invention discloses a method for selecting early-maturing yellow skin pepper germplasm and belongs to the technical field of plant breeding. Firstly, an ornamental pepper selfing population is subjected to sowing and seedling raising, and plants with viridescent cotyledon and euphylla are selected from the population in the cotyledon period and the euphylla period; in the flowering period, plants with about 10 initial flower sections, upward pedicels, milk white petals, faint yellow placentas, white styles and purple stripes on style tips are selected, and plants which do not conform to any of the features in the population continue to be removed; in the blooming period, each individual plant is covered with a nylon insect-proof mesh bag so that the plants can conduct selfing and fruiting, or selfing is conducted by means of artificial pollination; in the fruiting period, the colors of young fruits, commercially ripe fruits and physiologically ripe fruits are distinguished, individual plants with yellow young fruits and commercially ripe fruits and red physiologically ripe fruits are selected, and the fruits are harvested and seeds are obtained according to the individual plants; individual-plant selfing populations are sown respectively the next year, selection continues to be conducted according to the features, and if the plants in a certain individual-plant selfing population all conform to the features in all the periods, selection of homozygous early-maturing yellow skin pepper germplasm is completed; if the populations continue to be separated, selection continues to be conducted for 2-3 years according to the features.

Description

technical field [0001] A method for selecting germplasm of early-maturing yellow-skinned pepper belongs to the field of plant breeding, more specifically, a method for selecting early-maturing yellow-skinned pepper by combining seedling stage, flowering stage, fruiting stage selection and bagging or artificial selfing technology qualitative method. Background technique [0002] Early-maturing yellow-skinned peppers are rare germplasm resources of peppers. Not only are the fruits rich in nutrients, but they can also be used to breed parents of mid-early maturing light green pepper hybrids, mainly for quality breeding of peppers. The pepper has some typical characteristics in each period. The germplasm of early-maturing yellow-skinned pepper can be successfully selected by selecting according to the typical characteristics of each period and combined with bagging or artificial selfing technology. Without selection according to the above characteristics, it is very likely that...

Problems solved by technology

The pepper has some typical characteristics in each period. The germplasm of early-maturing yellow-skinned pepper can be successfully selected by selecting according to the typical characteristics of each period and combined with bagging or artificial selfing technology. Without selection according to the above characteristics, it is very likely that the early-maturing yellow-skinned pepper germplasm cannot be bred smoothly
