A kind of breeding method of large-fruited day-neutral strawberry

Abstract

The invention discloses a breeding method of a large fruit type day-neutralstrawberry. The breeding method comprises the steps as follows: parentselection, parent seedling breeding, parent cultivation in facilities, pollen collection, artificial hybridization, seed collection, hybrid seedling cultivation, character screening and variety test. The breeding method of the large fruit type day-neutralstrawberry has the following advantages: the day-neutral feature and excellent genes with high quality, large-fruit property, high yield and the like are subjected to efficient genetic recombination, strawberry varieties with good day-neutral feature, large-fruit property, high quality and high yield are bred, the fruit supply period can last from December to next August, the fruiting period is long, the yield is high, the problem of lack of the large fruit type day-neutral strawberry in the strawberry industry in China is solved, continuous annual production of forcing culture and culture in summer and autumn can be realized, the strawberry fruit supply period is prolonged, and the blank of strawberry summer market in China is filled up.

Description

technical field [0001] The invention relates to a method for breeding strawberry varieties, in particular to a method for breeding large-fruited day-neutral strawberries, which belongs to the field of fruit tree breeding. Background technique [0002] Strawberry has the advantages of less investment, quick results, economic benefits, etc., and the industry has developed rapidly. Strawberry fruit cannot be stored, and will soon become soft and rotten after ripening, so only fresh fruit can be supplied to the market. Making strawberries "longer fruit supply period" is not only the requirement of increasing the efficiency of strawberry production, but also the demand of the people for the fresh fruit market. According to the conditions required for flower bud differentiation and the fruiting period, strawberry production can be divided into three types: promoting cultivation, open field cultivation, and annual cultivation. Varieties suitable for open field cultivation have de...

Problems solved by technology

This method takes Zijin Siji as the female parent, cross-pollination with the selected cultivars Ningyu, Zhangji and other cultivars, so that the genetic recombination of daily neutrality and high quality, large fruit, high yield and other excellent genes can produce excellent hybrid breeding offspring It solves the problem of lack of neutral strawberries of large-fruited order in my country's strawberry industry, and can realize the continuous production of cultivation and summer and autumn cultivation. The fruit supply period can be from December to August of the next year. The fruiting period is long and the output is high, which fills my country's Strawberry summer market blank, high economic benefits
