For 25 years due to its unique properties the spring durum wheat variety “Saratovskaya zolotistaya” (1993) is popular not only among grain and pasta producers, but also among breeders of Russia and the CIS countries. Due to its high combining ability, the variety has been introduced in all breeding programs of research institutions engaged in the breeding and cultivation of spring durum wheat as a source of high content of carotenoid pigments.
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.
The purpose of the current work was to develop and introduce into production a spring durum wheat variety adapted to the climatic conditions of the Lower Volga region, which meets the modern requirements of the raw material market for pasta producers to productivity and grain quality. Grain quality is the most important criterion by which durum wheat is evaluated. For modern pasta production, there is a great need in grain with a grain unit of at least 770 g/l; with kernel hardness of at least 80.0%; with high quality of gluten (gluten index of at least 80 u.); with carotenoid pigments of 7.0–8.0 mg/kg, where the yellowness index (semolina color) is not less than 22.0 c.u. The new spring durum wheat variety ‘Tamara’ meets all the requirements. The variety was developed by the method of complex hybridization between the best varieties and lines of the laboratory for spring durum wheat breeding and seed production of the “FARC of South-East” and selected samples from the collections of the breeding centers of the Russian Federation, VIR, and ICARDA. The variety is middle-maturing, with 50 days from a germination to heading stage, with plant height of 96 cm. On average, through three years (2019–2021), the productivity of the variety exceeded that of the standard variety ‘Krasnokutka 13’ on 0.3 t/ha, and the variety ‘Saratovskaya zolotistaya’ on 0.5 t/ha. In 2020 in the production sowing of the Krasavskoye OPH the maximum productivity was 3.14 t/ha. The variety is characterized by a high percentage of carotenoid pigments, gluten elasticity and strength, an amber-yellow shade of spaghetti, their low digestibility, delicious taste and nutritional value. The new spring durum wheat variety ‘Tamara’ has been included in the State List of Breeding Achievements since 2022. The variety has been recommended for cultivation in the 8th region of the Russian Federation.
Introduction. Durum wheat is vital for high-quality pasta production. The present research tested the high technological potential of durum wheat varieties developed in the Saratov region. The research objective was to study the effect of the quality of durum wheat on the quality of pasta. Study objects and methods. The study featured durum wheat of the following varieties: Saratovskaya Zolotistaya, Valentina, Nik, Krasnokutka 13, Luch 25, Pamyati Vasilchuka, Bezenchukskaya 182 and Annushka. The experiment involved an original PSL-13 press for standard spaghetti with a diameter of 1.8 mm. The content of protein, raw gluten, and their quality were determined by standard methods. The cooking properties of the pasta were evaluated according to the method developed in the South-Eastern Federal Agricultural Research Center. Results and discussion. The indicators of raw gluten and protein are known to correlate. The samples of Saratovskaya Zolotistaya and Luch 25 had a high protein content of 15.3 and 15.6%, respectively, as well as a high content of raw gluten (33.2 and 35.1%, respectively). The raw gluten of Saratov varieties proved to be much better than in the control samples. The indicator of microSDs sedimentation was 30–36 mm. The strength of spaghetti followed the increase in crude gluten (33–35%) and protein (15.3–15.6%), which is typical of this type of pasta. The strength, coefficient of determination (R2 = 0.98), and sharing force (R2 = 0.92) depended on the protein content. Conclusion. The study established the following optimal selection criteria for durum wheat varieties to be used in strong spaghetti production: virtuosity – 80%, raw gluten – 33–35%, protein content – 5–7% higher than normal, raw gluten – 72–80 units.
