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

摘要: 遗传分析表明,枇杷果实成熟期及抗叶斑病属数量性状遗传;早熟对晚熟性状基因具有明显的遗传优势;抗叶斑病表现有母性遗传的趋势。提出了枇杷成熟期和抗叶斑病育种对亲本选择选配的意见。

Abstract: 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.
