THE SELECTION METHODS OF SELF-POLLINATION AND NORMAL CROSS POLLINATION IN POPULATION, VARIETY OF CROPS

摘要

The invention relates to the field of crops selection and breeding, particularly relates to the selection methods of self-pollination and normal cross-pollination in population, variety of crops. The selection method includes crossing male parents with female parents to obtain rice populations, wherein the female parents are individual plants which obtained from intercross parents which have different target characters, to produce F1, which is then intercrossed to produce individual plants of separated population, or are separated plants, which is obtained from the inbreeding of individual plant. The male parents are selected from pure line or variety or heterozygous progenies. The method includes five stages of cross, stable self-bred, determination, classification and population improvement. The population and variety have the characteristics of consistency, stability, specificity, farmers' reserving seeds properly, Company's exploiting pedigree seed in a large scale, and also have the characters of highly adaptability, disease resistance and high yielding. The breeding process reduces the dependence on exports' experience, and also adapts for selection for farmers.
