摘要: 【目的】 分析新疆红肉苹果(Malus sieversii f. Neidzwetzkyana (Dieck) Langenf.)的果实特性及MYB10基因的启动子类型,为研究新疆的红肉基因类型及红肉苹果资源的利用研究奠定基础。【方法】 测定果实单果重、纵径、横径等性状指标并观察果肉颜色,设计引物,利用PCR克隆的方法,进行启动子类型检测。【结果】 果肉颜色多为淡红色,丝状或片状分布,HX-1为血红色果肉全红,单果重变异系数较大,最大单果重为124.57 g,果形指数最大值1.01,最小值0.82;可溶性固形物最大值17.36,最小值10.66;果梗粗最大值2.50 mm,最小值1.02 mm;果梗长度最大值34.36 mm,最小值13.48 mm;MYB10启动子类型全部为R6R1型。【结论】 29份资源的果实性状的遗传多样性较为丰富,果肉的呈色各有特点,但MYB10启动子类型全部一致为R6R1型。

Abstract: 【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.

Key words: red fresh apple; MYB10; promoter
