Abstract

Walnut (Juglans regia L.) is one of the main nut crops of world importance. The conservation and effective use of walnut genetic resources is one of the fundamental principles of breeding work. Therefore, it is important to study the distribution of walnut (Juglans regia L.) and their diversity, for a new breeding program and selection of excellent genotypes. For this purpose, the distribution of Juglans regia L. was monitored in the southern and southeastern regions of Kazakhstan and phenotyping of nut fruit quality indicators. As a result of the expedition work, a collection of 60 walnut samples was formed: 30 samples from the Sairam-Ugam State National Natural Park, 7 trees from the village of Mashat, Tulkubas district of Turkestan region, 10 trees near the village of Sarkyrama in the Saryagash district of Turkestan region, 7 samples from the Kyrgyz Republic and 6 walnut trees from the Almaty region. Herbarium material and fruits of the walnut were collected from all the trees. (60 genotypes) indicating the geographical coordinates of the collection site based on GPS, for further work in genetic research. As a result of phenotyping of the walnut collection (Juglans regia L.) in terms of fruit quality, it was revealed that the walnut fruits collected on the territory of Mashat village, in comparison with the collection, differed in the largest size with a diameter of 3.28±0.17 cm and a length of 3.29±0.21 cm. In a comparative assessment of fruit quality by kernel weight and kernel yield, the most productive samples №51 (6.20±0.04 g) were identified, 54,13±3,47%), №1 (5,97±0,41 g, 53,74±2,02%), №34 (5,48±0,39 g, 52.30±0.45%), №50 (5.35±0.56 g, 47,43±2,70%), №59 (5,11±0,62 39.09±2.20%) and №24 (5.07±0.72 g, 45.18±2.70%).
