Method for breeding Liaofeng grape variety

Abstract

The invention provides a method for breeding Liaofeng grapes, which relates to a method for breeding a new variety of grapes. The method is invented mainly for solving the problems that the prior Kyoho grape is poor in resistance to downy mildew, white rot and spot anthracnose, low in sugar content, fruit grain weight and yield, short in shelf life and the like. During grape cultivation, the method comprises the following steps of persisting in continuously selecting superior and eliminating inferior in a long time, meticulously cultivating, carefully observing growth changes of every grape plant, picking out a plurality of optimal single plants every year, cultivating and contrasting. The fruit grain of the Liaofeng grapes bred by the method weighs 9 to 10 grams, and the yield of the Liaofeng grapes is increased by 5 to 10 percent compared with the Kyoho grape. In addition, the Liaofeng grapes have no too big / small fruit grains or dehiscent fruits, are luxuriant in branches and leaves, have the maximum leaf diameter up to 35 centimeters, have the shelf life up to 6 to 7 days, and can endure storage and transportation.

Description

Technical field: [0001] The invention relates to a method for breeding new grape varieties. Background technique: [0002] The Kyoho grape introduced from Japan 40 years ago is still one of the main varieties in the main grape-producing areas of Northeast my country, but the main disadvantage of this variety is its poor resistance to downy mildew, white rot, and black pox , the sugar content, fruit weight and high yield also need to be improved; and because the shelf life is only 3 to 4 days, the storage and transportation resistance is also poor. Invention content: [0003] The technical problem to be solved by the present invention is to provide a method for breeding Liaofeng grape varieties that can overcome the above-mentioned shortcomings of Kyoho grapes. [0004] The purpose of the present invention is achieved by the following scheme: in the grape cultivation process, adhere to the long-term continuous selection of the superior and eliminate the inferior, carefully ...
