Abstract

The article provides information about the form diversity and selection of walnuts in the natural walnut forests of Kyrgyzstan. In walnutfruit forests, there is a wide variety of forms of walnut and other wild fruit species. The species and intraspecific diversity of wild fruit trees and shrubs allows selecting the best forms for creating highly productive plantations in various forest conditions in order to obtain high yields of nuts and other fruits. Methods of selection and criteria for selecting the best forms of walnuts are described.

Highlights

  • Walnut is an important nut crop, a lot of work on studying local walnut populations and registering the best trees as varieties in recent decades has been carried out in many countries with developed walnut production

  • Natural walnut forests in the belt of walnut-fruit forests and cultural plantations growing in valley conditions are an object for studying the form diversity and selection of the prospecting walnut genotypes

  • Walnut forests are of great value both in terms of raw materials and water protection, and from a scientific point of view

Summary

Introduction

Walnut is an important nut crop, a lot of work on studying local walnut populations and registering the best trees as varieties in recent decades has been carried out in many countries with developed walnut production. The objectives of the program include improving varieties for the California nut industry, developing better knowledge and methods to make breeding more efficient, developing and maintaining a variety of forms with traits useful for future breeding, and applying new molecular and genomic methods to improve walnuts. The best varieties are the Chandler, Hartley and others, which begin their growing season 15-18 days later, other.
