USPP37151P2 - Cherry plum tree named ‘Farmer 3-01’ - Google Patents

Abstract

The new cherry plum variety ‘Farmer 3-01’ is characterized by having a semi-open tree posture, and black colored, soft textured fruits with orange yellow colored flesh.

Description

Latin name of the genus and species claimed: Prunus cerasifera.

Variety denomination: ‘Farmer 3-01’.

BACKGROUND AND SUMMARY OF THE NEW VARIETY

This application relates to the discovery and asexual propagation of a new and distinct variety of cherry plum tree, Prunus cerasifera ‘Farmer 3-01’. The new variety ‘Farmer 3-01’ was developed by using wild cherry plums found at an altitude of 1,100-1,600 m in Daxigou and Xiaoxigou, Huocheng County, Xinjiang, China, as parents. The new variety ‘Farmer 3-01’ resulted from sowing wild cherry plums and natural pollination. The new variety was selected and propagated through seedling breeding, high grafting propagation, and strain comparison experiments by Qiong He, Zhiqiang Bai and Xiaobo Cheng. The new variety ‘Farmer 3-01’ was asexually reproduced in Huocheng County, Yili, Xinjiang, China, by grafting.

The new variety ‘Farmer 3-01’ is characterized by having a semi-open tree posture, and black colored, soft-textured fruits with orange yellow flesh.

The new variety ‘Farmer 3-01’ has black colored fruit skin compared to the purple-red colored fruit skin for ‘Zishouyao’ (unpatented). The fruit stalk of the new variety ‘Farmer 3-01’ is shorter than ‘Zishouyao’. Additionally, the fruit texture of the new variety ‘Farmer 3-01’ is soft, compared to the medium texture for ‘Zishouyao’. Lastly, the new variety ‘Farmer 3-01’ has a semi-open tree posture, compared to the open tree posture of ‘Zishouyao’.

The detailed breeding process of ‘Farmer 3-01’ is described as follows:

In 1995, in Huocheng County, Yili, Xinjiang, wild cherry plum seeds were collected for sowing and breeding wild cherry plum live seedlings. After five years of repetitive investigation and comparison from 2002 to 2006, the single plants having stable traits, early fruiting, high productivity, high stress resistance, and good processing performance were screened, and in 2007, the scions of the screened single plants were collected and grafted onto 3-year-old bionic cultivated cherry plum trees through high grafting to obtain ‘Farmer 3-01’.
