Abstract

Background. In 1991, under the cooperation agreement, the Federal Center of Agriculture Research (FCAR) of the South-East Region received the first improved accessions from the International Center for Agricultural Research in the Dry Areas (ICARDA). The objective of this work was to study the source material developed under comparable conditions of dryland agriculture and include the best accessions in scientific breeding programs.Material and methods. The presented data resulted from the study of spring durum wheat cultivars and lines from ICARDA (Aleppo, Syria), conducted in 1991–1998. Accessions with the best indicators of grain quality, adapted to the conditions of the Lower Volga, were selected and included into the crossing program. Grain analysis was carried out using the conventional methods for durum wheat as well as those modified by the Spring Durum Wheat Breeding Laboratory of the FCAR of the South-East.Result and conclusion. Many years of work led to identifying 22 lines of spring durum wheat, selected in the breeding nursery of the Main Competitive Trails (MCT) and in different years involved in complex multistep hybridization. The spring durum wheat cultivar ‘Lilek’ was included into the State Register for Selection Achievements in 2009, while cv. ‘Tamara’ was submitted to the State Variety Trials in 2020.

Summary

Background

In 1991, under the cooperation agreement, the Federal Center of Agriculture Research (FCAR) of the SouthEast Region received the first improved accessions from the International Center for Agricultural Research in the Dry Areas (ICARDA). Такие условия не позволяют получать стабильные урожаи зерна ранних яровых зерновых культур, в том числе и твердой пшеницы, но дают хорошую возможность селекционерам оценить и отобрать засухоустойчивые генотипы в процессе селекции (Vassiltchouk et al, 2010). В течение последующих восьми лет коллективом лаборатории селекции и семеноводства яровой твердой пшеницы было изучено около тысячи (991) линий и сортов, поступивших из ICARDA. Применялись общепринятые методики для твердой пшеницы (Remeslo, 1971) и усовершенствованные в лаборатории селекции НИИСХ Юго-Востока (Vassiltchouk et al, 2001). Количество выпавших осадков (118 мм) было всего на 51 мм меньше, чем среднемноголетнее значение (169 мм за вегетацию), и дней с суховеями отмечено 22. Был близок к норме (среднемноголетнее их количество составляет 154 мм), однако наблюдалось большое число дней с суховеями, то есть с дефицитом влажности более 16 мб.
