According to Chunfeng, a new peach variety Tainong 3, what are the characteristics of Chunfeng variety Tainong 3?

Peach tree has been a symbol of longevity and auspiciousness since ancient times. Fresh peach fruit is not only perfect in appearance, bright in color, but also juicy and delicious, fragrant and attractive, so it is loved by Chinese people. According to the 1999 Agricultural Statistical Annual report of the Republic of China, Taiwan's peach planting area was 2404 hectares, with an annual output of 28000 metric tons and an output value of NT $1.32 billion, mainly in the central and northern regions.

The cultivation and production of peach trees in Taiwan are mainly divided into two production types: high mountains and flat land. in order to alleviate the pressure on the environment caused by alpine reclamation, the government actively supports the research and development of peach varieties for the localization of peach trees and creates an environmentally friendly peach industry. Since 1980, the Agricultural Test Institute has successively developed new early, middle and late ripening peach varieties with low cold demand, low acid, early maturity, large fruit, bright appearance and good quality, which are suitable for planting in flat land. at present, flat honey peach accounts for more than 60% of the total cultivated area, effectively expanding the scale of flat honey peach industry, and has a development trend to the south.

The new variety Tainong 3 was cross-pollinated by & # 39; Tainong Sweet & # 39; as its female parent and pollen parent & # 39; Fozhouhong & # 39 in 1986. In October 1998, it bred a new variety and obtained the variety right. The trade name is & # 39; Chunfeng & # 39; is the intention of early maturity and high yield. The new variety has the characteristics of high yield, excellent pulp texture and male parent & # 39; Fuzhouhong & # 39; early ripening and large fruit; at the same time, it makes up for the shortcomings of & # 39; Tainong sweet & # 39; fruit is not much the same as & # 39; Fuzhouhong & # 39; fruit acidity is too high.

& # 39; Chunfeng & # 39; good fruit bearing, fruit development days 81-90 days, is an early-maturing species, the full-blooming period is about 11 days earlier than the main commercial varieties in flat land & # 39; Tainong Sweet & # 39; Fruit weight can reach 5 to 6 taels (187.5 to 225g), which is a large fruit, which is larger than & # 39; Tainong Sweet & # 39; The fruit is round in shape, the suture is shallow, and the fruit has good symmetry. Fluffy, red pericarp, milky yellow background, easy to peel. The pulp is white, less coloring near the core, soft solute, high sugar content (up to 12 degrees), low acidity (only 0.4%), sweet flavor and strong aroma.

Because the fruit matures early, the application of phosphorus, potassium, calcium and magnesium fertilizer should be strengthened 3-4 weeks before harvest to inhibit the growth of new shoots so as to promote the accumulation of nutrients and improve the sweetness of fruit. When the fruit was harvested, the pericarp velvet density was much higher than that of the female parent & # 39; Tainong Sweet & # 39; the pericarp was thicker and resistant to Rain Water, and the degree of water injury was less than that of & # 39; Tainong Sweet & # 39; Chunfeng & # 39; has shallow dormancy and is suitable for planting in flat land and shallow hillside areas in central Taiwan. the overall taste is sweet and rich, the flavor is excellent, the yield is high, the economic value is high, and it has great potential for popularization. it has been exclusively authorized manufacturers to carry out seedling reproduction, sales and promotion.
