KEYWORDS Selection and seed production, yield, early maturity, source material, intensive variety, varietal samples, hybridization, heredity, grain quality, strong and valuable, yield. INTRODUCTION In recent years, potential varieties of soft winter wheat for irrigated lands of 80-100 t / ha, high-quality grain, disease and pest resistant varieties have been created in the Republic of Uzbekistan, which have a significant impact on increasing grain production and increasing the productivity of farms. However, the bulk of the grain grown in the country is sold at third-grade purchasing prices. This indicates that in the selection and technology of growing wheat, along with yield, great attention should be paid to indicators of grain quality. Abundant and high-quality wheat cultivation is carried out through the use of cultivation technology in Wheat Breeding Research In The Zarafshan Oasis Of The Republic Of Uzbekistan Gaybullayev Gulom Saydalimovich Professor, Dsc, Samarkand Institute Of Veterinary Medicine, Samarkand, Uzbekistan Bolbekov Makhsud Abduvakhobovich Assistant, Samarkand Institute Of Veterinary Medicine, Samarkand, Uzbekistan Tuygunov Rasul Bolibekovich Assistant, Samarkand Institute Of Veterinary Medicine, Samarkand, Uzbekistan Journal Website: http://usajournalshub.c om/index,php/tajabe Copyright: Original content from this work may be used under the terms of the creative commons attributes 4.0 licence.
