Analysis on Fruit Characteristics and Genotype of MYB10 Promoter in Xinjiang Red-Fleshed Apple

【Objective】 To study the promoter type of red fresh gene MYB10 in Xinjiang red fresh apple (Malus sieversiif neidzwetzkyana (Dieck) Langenf and the fruit characteristics. The results lay a foundation for further study on red fresh apple breeding in Xinjiang. 【Methods】 The promoter type of 29 red fresh apple were detected by PCR cloning,measured fruit weight,diameter and observed the color of the flesh. 【Results】 The color of flesh was light red, The red part was not continuously distributed in the pulp.The variation coefficients of friut weight were 57.10%,the maximum of single fruit weight was 124.57 g;The shape index of fruit maximum was 1.01, the minimum was 0.82; The soluble solids content maximum was 17.36, minimum value was 10.66; The thickness of stalk maximum was is 2.50 mm, minimum value was 1.02 mm;The length of stalk maximum was 34.36 mm,minimum value was 13.48 mm;The MYB10 promoter type of 29 germplasm red fresh apple was R6R1. 【Conclusion】 The same type of promoter of 29 red fresh apples was R6R1, The fruit characters had abundant genetic diversity and The red part in the pulp was not continuously distributed.
