鲜食加工兼用型黄桃优变株系选育研究

Breeding of Superior Variant Strains of Yellow Peach Used for Fresh and Processing

系统观察结果表明,5个鲜食加工兼用型‘黄桃’优变株系与来源品种相比,果型较大,锦绣黄桃的4个优变株系单果重均增加50 g以上,‘锦黄’增加16.6 g;‘硕锦1号’展叶期前各物候期较迟,盛花期延后5～7 d;‘锦黄’果实成熟期推迟约45 d;‘硕锦1号’、‘硕锦3号’、‘硕锦4号’、‘锦黄’果形为椭圆形、长椭圆形,与来源品种相似,‘硕锦2号’则以尖圆为主;‘锦黄’风味酸甜,明显异于‘丰黄’;各优变株系既符合黄桃鲜销市场供求走势,又能满足果品加工企业的原料需求,均显现出良好的选育前景与应用开发潜力。

Systematic observation results showed that 5 superior variant strains of yellow peach used for fresh and processing had bigger fruit type than that of original species,4 superior variant strains of ＇Jinxiu＇ single fruit weight increased more than 50 g,＇Jinhuang＇ increased 16.6 g;The phenophases before leaf development was delayed and late flowering 5～7 d in ＇Shuojin 1＇,fruit maturity of ＇Jinhuang＇ delayed about 45 d;The fruit shape of ＇Shuojin 1＇,＇Shuojin 3＇,＇Shuojin 4＇ and ＇Jinhuang＇ was oval,oblong and similar with original species,＇Shuojin 2＇ was mainly round;＇Jinhuang＇ had sweet and sour flavor,noticeably different from ＇Fenghuang＇.The superior variant strains not only accord with the demand of fresh peach sales market,but also meet the needs of raw materials for fruit processing enterprises,so they appear good breeding potential and application prospects.
