Abstract
The article presents the results of a study devoted to determining the duration of the growing season in collectible samples of spring soft wheat. The study of the collection was carried out by the laboratory of genetic resources of grain crops of the A.I. Barayev Scientific Research Center of the Grain Farming in the period 2020-2022.
During the research, the duration of the growing season of the samples and the relationship between the duration of the growing season and the yield of the samples were studied. Among 60 samples of soft wheat, according to the results of studies conducted over an average of three years, precocious samples were identified: Demonstrant, Erythrospermum 79/07, Tyumenskaya 32, Lutescens SHT-335, Line 2026. The late-maturing samples over the years of study included the following samples: Chelyaba 80, Lutescens 1135, L. 654, Sibakovskaya Jubilee.
On average, over the years of studying the collection samples, 25% of the samples had a period of "germination-earing" of 33-37 days, 43% of the samples 38-40 days and 32% of the samples 41-46 days. Spring wheat cultivars Lutescens 1003, Lutescens 1012, L. 654, Lutescens 1135 distinguished themselves by an extended period of "sprouting-earing". The "earing-ripening" period of spring soft wheat ranged from 39 to 51 days. For a shorter period (40-41 days), such samples as: Lutescens 230/00, Lutescens 1082, Lutescens 1003, Lutescens 1012, etc. were distinguished.
The correlation dependence of the elements of the crop structure and the growing season is determined, the coefficient of variation by characteristics is analyzed. Samples have been selected that have the potential to be the basis for the development of new varieties of soft wheat within the framework of breeding programs specially adapted to the climatic conditions of Northern Kazakhstan.
