Study on Heredity of Several Characters in Loquat I. Genetic Trendency of Fruit Agronomic Characters

The genetic trendency of fruit agronomic characters of 209 hybrid progenies from 14 cross combinations were analysed. The result showed as follow: Weight and shape of fruit, multiple quality belong to quantitative inheritance. Hybrid progenies had wide and continuous segregation, which showed the general rules of degenerated economic characters and the trendency of middle-taxis variance in hybridization and seedling multiplication of loquat. The heredity for color of peel and flesh is in accordance with a complicated pattern,and may be attributed to the incompletely dominant inheritance controlled by one pair or several pairs of gene. In this paper, the suggestions of selecting parent materials for cross-breeding in loquat were also made.
