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.
