Breeding report of a new ornamental peach cultivar Yanfen No.4
摘要
Abstract
Yanfen No.4 is a new ornamental peach cultivar developed by crossbreeding Yanhongzao-hua peach as the female parent and Zaotian peach as the male parent.It was initially selected in 2013.Through artificial hybridization pollination,30 hybrid seeds was obtained.In March 2015,after the flowering of 20 seedlings,an excellent individual plant with specific performance was found.The ini-tial flowering period of this individual plant was around March 5th,12 days earlier than the check vari-ety Yanhongzaohua.The flower was pink and of high ornamental value.Subsequently,peach was used as the rootstock for grafting and propagation.In 2016,after the flowering of grafted seedlings,the phe-notype features and phenological phases were observed and recorded.Through comparison,it was found that its traits were stable and consistent with the performance of the mother plant.After regional adaptability testing over five years from 2016 to 2020,it was finally selected in 2023.The tree is moder-ately open and has straight branches.The internodes are long with an average length of 1.6 cm.The flowers usually grow on short branches,with an average of 42 flowers per branch.It is easy to produce flowers,with moderate number of flower buds.The flower is plum-blossom-shaped and double petal,with an average diameter of 4.1 cm and an average number of 19 petals.The flower bud and the petals are all pink.There are 10 pieces of reddish brown sepals.The average number of filaments is 49.The anthers are tangerine with pollen.The stamens are almost of the same length as the petals.There is one pistil,which is almost the same length as the anthers.The leaves are green and lanceolate with flat sur-face.The peel is green-white with medium fuzz.The fruit is large and round.The stone is oval-shaped with moderate number of stone veins.In Xuchang of Henan province,the initial flowering period is on March 5th,12 days earlier than the check variety.The peak flowering period lasts from March 10th to 20th,and the final flowering period is on early March 23th.The flowering period lasts for about 18 days.Yanfen No.4 is resistant to drought,cold and adversity.It has wide adaptability.It is suitable for plant-ing in areas where the chilling requirement of 300-500 hours can be met.Grafting method is used for re-production.Hard branch grafting can be used in early spring and bud grafting should be carried out be-fore June 10th,using peach as the rootstock.It is suitable for planting at a space of 2 m × 3 m or 2 m ×3 m.In the early stage of pruning,the main focus is on cultivating tree shape,while in the later stage,the vig-orous growth is controlled to promote flower bud differentiation.After rainfall or watering during the growing season,the soil should be plowed and loosened timely.The depth of tillage is 5 cm to 10 cm.Ev-ery autumn,base manure should be applied and the soil should be deeply plowed with a depth of 30 cm to 40 cm.Fertilizer should be applied once a year in May and July respectively.关键词
