Breeding method for good-quality high-yield grape variety suitable for growing in northern Hunan

Abstract

A breeding method for a good-quality high-yield grape variety suitable for growing in northern Hunan comprises the following steps that (1) high-quality wild grape plants in Mountain Wuling are collected as tree stocks, 'Hutai NO.8' branches are used as scions, and the first time of grafting is carried out; (2) high-quality wild grape plants in Mountain Xuefeng are collected as tree stocks, 'Hutai NO.8' branches are used as scions, and the second time of grafting is carried out; (3) Xuefeng seedlings are used as tree stocks, Wuling seedling branches are used as scions, the third time of grafting is carried out, and seedling branches which are alive in the third time of grafting are used for cuttage. When the new grape variety is planted, besides the common method that retting-matured chicken manure, pig manure and biogas residue organic fertilizer are applied to soil, bacterial manure and little grape biological modifier are further used. A grape fruiter planted through the method has the advantages that fruit quality is good, yield is high and stable, fruits mature early and fall later and are yielded continuously, fruiter stress resistance is strong, fruit cracking can not happen, and fruits can be stored and transported for a long time.

Description

technical field [0001] The invention relates to the breeding of grapes, that is, a method for breeding high-quality and high-yielding grape varieties suitable for growth in northern Hunan. Background technique [0002] The area and output of fruit tree cultivation in the world ranks second only to citrus. Grapes are widely loved by people for their beautiful color and shape, sweet taste and rich nutrition. There are many varieties of grapes. The foreign grape varieties introduced and planted in China include Zhana, White Banana, Kyoho, Fujiminori, etc. Zhana has the advantage of early maturity, but the disadvantages are small fruit, cracked fruit, and poor resistance. White Banana The yield is high, but the fruit is small and easy to fall. Kyoho has the advantages of large fruit, but the yield is low and the growth is weak. Fujiminori has the advantages of large fruit and high yield, but there are cracks and difficulties in storage and transportation. Now Some grape varieti...

There are many varieties of grapes. The foreign grape varieties introduced and planted in China include Zhana, White Banana, Kyoho, Fujiminori, etc. Zhana has the advantage of early maturity, but the disadvantages are small fruit, cracked fruit, and poor resistance. White Banana The yield is high, but the fruit is small and easy to fall. Kyoho has the advantages of large fruit, but the yield is low and the growth is weak. Fujiminori has the advantages of large fruit and high yield, but there are cracks and difficulties in storage and transportation. Now Some grape varieties can only bear fruit once a year, and the fruiting period is short

In recent years, many attempts have been made to cultivate grapes in northern Hunan, but they are all imported foreign varieties. It is difficult to find a high-quality and high-yielding grape variety suitable for the growth of northern Hunan.
