| Abstract: | Chunyuan,an extra early season peach cultivar,was derived from the cross of Zaoxiangyu×81-4-2 (Wuhe×Zaoxiangyu) with the help of rescuing inherently weak,immature hybrid embryos by embryo culture technology. The trees are medium vigor,precocious,productive and self-fruitful. Its fruits ripen in early June in the field or in late April to early May in simple plastic greenhouse in Qingdao. The duration of fruit development period is about 58 days. At maturity,the fruit surface is covered by 95 percent bright red with an attractive light yellow background color and round regular shape. The flesh of this freestone fruit is white,tender,juicy and sweet,with a soluble solids content of 11% to 13.5%. It is firm,with excellent texture and good flavor. The average fruit weight is 100 g,but reaching 138 g. Chunyuan is widely adaptable in Shandong and recommended to be used for the production both in the field and simple plastic greenhouse. |
