The Genetic Analysis on Special Materials of Natural Flowering and Self Fruitfulness in Sweet Potato
Law of Genetic Variation of sweet potato was studied by using special materials of natural flowering and self fruitfulness that were used to create segregating population by self-pollination, hybridization and reciprocal cross. Selecting natural flowering and self fruitfulness lines from the descendants broke down the genetic block of selfing and hybridization in sweet potato. In this study, breeding material genes of sweet potato were homozygous ac cumulated, selfing breeding parents was applied and breeding program was simplified.
