THE INFLUENCE OF HOT-DRY WIND ON FARM VALUABLE TRAITS OF WHEAT GENOTYPES IN SOUTHERN REGIONS OF ....

It is critical to create and layout scientifically based cereal varieties with consistent quality traits that can give a stable yield, adaptable to a specific region's conditions by taking into account soil and climatic conditions for the cultivation of high-quality grain with high yields in various regions.

A particular programme for research activity was designed to explore the aforementioned problems associated with conditions. During the years 2012-2014, experiments were carried out on the farms "Surkhon Khalkaobod sardori" in Termiz district of Surkhandarya and "Kungirot Alpomish farm" in Mirishkor district of Kashkadarya region. 36 kinds and lines were studied in three replications during the experiments. As a local check variant, the Krasnodar-99 variety, which is widely produced in this region, was chosen. Planting of kinds and lines in November, during the late sowing time, was done to comprehensively explore the hot-dry wind resistance capabilities. When types and lines are planted late in the season, they are exposed to hot, dry winds during germination, flowering, and grain filling, making it simpler to determine resistance levels. Weather data, phenological observations, and laboratory analyses were all collected as part of the research. The program's outcomes and analysis were analysed, and the relationship between productivity and other important economic characteristics was investigated.

Daily air temperature, wind speed, and relative humidity were measured during the research. Changes in the developmental phases of varieties, plant height (cm), spike length (cm), number of grains in single spike (pieces), grain weight in single spike (g), 1000 grains weight (g), test weight (g / l), protein content (percent), and gluten content (percent) were studied in the conditions of Kashkadarya and Surkhandarya under the influence of hot wind (hot and dry wind). When the data was analysed, it was discovered that the hot, dry wind had a major impact on the features of bread wheat types and lines, allowing for the selection of resistant kinds.

KR11-105-50 (Kesh-2016), KR11-105-44 (Shukrona), and KR11-105-43 (Shams) varieties of winter bread wheat were proven to be resistant to hot and dry wind conditions. It was suggested that these types be widely distributed in the Republic of Uzbekistan's hot, arid, windy regions. In hybridization efforts, resistant to hot and dry environments varieties can be employed as donors.
