英文摘要：

‘Yumeiren＇ is a new early-maturing peach cultivar which is derived trom the cross ‘Yubai＇ × ‘Xinhongpao＇ in 1992. ＇Yubai＇ and ＇Xinhongpao＇ are middle-maturing peach cuhivar and early-maturing peach eultivar bred by Henan Agricultural University, respectively. The anthers of ＇Xinhongpao＇ at big bud stage were collected. 280 flowers of female parent removed the corollas were pollinated and hagged in April 7, 1992. 106 fruits of the cross were harvested and cleaned seeds were stratification treat- ment. 57 seedlings were obtained and planted at 0.5 m × 1 m in density in the next spring. ＇92-4-1-2＇ was selected after more than five years identification and tests. After selection as ＇92-4-1-2＇ in 2010, the bud wood from this selection was grafted onto Chinese wild peach （＇Maotao＇） seedling rootstocks and planted in four sites in Henan province. The cultivar comparison trials with ＇Chunyan＇ as control were conducted from 2010 to 2014 at each site. All testing trees were trained as open-center-natural form spaced 3 m between trees in rows spaced 5 m apart. The tree, flower and fruit characteristics of ＇92-4-1-2＇ eventually named ＇Yumeiren＇ were assessed in comparison trials from 2012 to 2014. After 5 years of eval- uation, the characteristics of ＇Yumeiren＇ were obviously better than ＇Chunyan＇. Trees of ＇Yumeiren＇ are moderately vigorous with a semi-upright growth habit similar to ＇Chunyan＇. Leaves of ＇Yumeiren＇ tree have reniform nectaries, and the average leaf size is 3.9 cm wide and 16.0 cm long. The fruits of ＇Yu- meiren＇ are mainly set on long branches. ＇ Yumeiren＇ has been shown to exhibit higher yields than ＇ Chunyan＇. This yield difference was increased with tree age. Full bloom date of ＇Yumeiren＇ in Henan prov- ince was early-April as was control. The earliest full bloom of ＇Yumeiren＇ was observed on Mar. 28 at Nanyang which located in the southwest region of Henan province. The flowers of ＇Yumeiren＇ are non- showy
