Background. Stem rust of wheat, caused by the biotrophic fungus Puccinia graminis Pers. f. sp. tritici Eriks. et Henn., is a dangerous disease that afflicts serious economic damage to the cultivation of durum wheat.Materials and methods. Cultivars and promising materials developed at the Spring Durum Wheat Breeding Laboratory, Omsk Agrarian Scientific Center (OASC), lines obtained under the CIMMYT and KASIB programs, and accessions from the VIR collection were the objects of research. Field experiments, phenological observations, and assessment of stem rust resistance were carried out from 1990 through 2019 in the OASC experimental fields using conventional methods. Resistance to the Ug99 race was evaluated under natural infection pressure at the Kenya Agricultural and Livestock Research Organization (KALRO).Results. Promising source material was identified and included in the Laboratory’s breeding program. The ways were shown to develop stable cultivars of spring durum wheat for the environments of Western Siberia. A strategy was proposed for the selection of genotypes in hybrid combinations of spring durum wheat: it would include early selection (starting from F2 ) for disease resistance with simultaneous screening for quantitative traits and pasta-making qualities. The description and advantages of cv. ‘Omsky korall’, submitted to the State Variety Trials in 2018, are presented. This cultivar combines high yield, adaptability, resistance to the local population and the Ug99 race of the stem rust pathogen, and excellent pasta-making qualities.Conclusion. As a result of these studies under heavy stem rust pressure in Western Siberia, all breeding nurseries obtained source material resistant to the Omsk population of P. graminis. The released cultivars ‘Omskaya yantarnaya’ and ‘Omsky izumrud’ demonstrate resistance to the Omsk population of the stem rust causative agent.

“…Lodging is often caused by a combination of wind and rain in the late growth stage of wheat. A group of traits which can be used as predictors of lodging resistance of wheat are plant height, lengths of the basal first and second internodes, culm diameter and culm weight per cm (Yusov and Evdokimov, 2008;Kong et al, 2013). Analysis of quantitative information about these traits could improve understanding of the stem lodging resistance of plants in the late growth stage of wheat.…”

A field micro-plot experiment was conducted to study the effect of early-stage regulated deficit irrigation (RDI) on the stress tolerance of winter wheat in the late growth stage. Plants were subjected to two RDI treatments: proper water deficits (45-55% field water capacity) were imposed during tillering-the beginning of the spring growth stage (T1) and during the beginning of spring growth to the end of the stem elongation stage (T2). The control plants (CK) were maintained with an adequate water supply until anthesis. The results showed that T1 and T2 shortened the length of the first and second internodes, and increased their weight per unit length, and thereby enhanced stem lodging resistance. Although post-anthesis drought and waterlogging lowered leaf photosynthetic rate and root respiration rate, the two RDI treatments improved significantly compared to the control. The two RDI treatments had no significant effects on grain yield under post-anthesis well-watered conditions but increased grain yield and yield stability of wheat under post-anthesis water stress. In addition, T1 and T2 significantly reduced water consumption and increased water productivity (WP) of wheat compared to the control. In summary, this study shows that appropriate RDI at early growth stages increased grain yield and yield stability through improving population characteristics, root respiration and photosynthesis of plants under post-anthesis water stress conditions.

Les plantes ont été soumises à deux traitements de RDI: les déficits en eau ont été imposés du tallage au stade de développement de la pousse (T1), et de ce stade à la fin du stade tige d'allongement de la tige (T2). Les plantes de contrôle (CK) ont eu un approvisionnement en eau adéquat jusqu'à la floraison. Les résultats ont montré que T1 et T2 raccourcissent la longueur des premier et deuxième inter-noeuds, et augmentent leur poids par unité de longueur, et, par voie de conséquence, augmentent la résistance de la tige. Bien que la sécheresse et l'engorgement post-anthèse aient abaissé le taux de photosynthèse des feuilles et le taux de respiration des racines, les deux traitements de RDI ont montré une amélioration considérable du rendement par rapport au contrôle. Les deux traitements RDI n'ont pas montré d'effet significatif sur le rendement en grain en cas de post-anthèse correctement arrosée, alors que ce même rendement a augmenté et avec une meilleure stabilité dans le cas de post-anthèse hydriquement stressée. En outre, T1 et T2 se sont accompagnés d'une réduction significative de la consommation en eau du blé et de l'augmentation de la productivité de l'e...
