Study on Heredity of Several Characters in LoquatⅡ.Genetic Tendency in Fruit Mature Period and Resistance to Leaf Spot

Genetic analysis showed that mature period of fruit and resistance to leaf spot in loquat belonged to genetics of quantitative character s.Early maturing of character genetic had clearg enetic dominance to late maturing.Resistance to leaf spot showed at endency to mat ernal inheritance.In this paper,the suggestions of selecting parent materials in mature period and resistance to leaf spot breeding in loquat were also made.
