Abstract
In order to develop rice breeding material of a functional direction, technological and biochemical grain quality traits of varieties bred by the Federal Scientific Rice Centre (Rubin, Mars, Mavr, Gagat, Yuzhnaya noch) with a colored grain pericarp, high content of anthocyanins and intended for functional nutrition were studied. The varieties were grown in the valley agrolandscape zone of Krasnodar region (Russia) in 2017–2019. The studied rice varieties are included in the State Register of Protected Breeding Achievements. The grain size by weight of 1000 absolutely dry grains (weight of 1000 a.d.g.) was determined according to GOST 10842-89, fracturing on a DSZ-3 diaphanoscope, protein content was measured using an Infralum FT-10 device. The determination of amylose was carried out colorimetrically using the amylose-iodine reaction according to Juliano. The varieties have a medium-sized caryopsis (21.5-27.0 g of 1000 grains); of them, the variety Yuzhnaya noch is characterized by the smallest grain. The variety Mars belongs to the low amylose group, varieties Mavr, Rubin and Gagat to the medium amylose group, Yuzhnaya noch to the waxy group. In terms of protein content in grain, all varieties are classified as medium protein. The maximum grain fracture was in variety Mavr in the range of 19-25% and the minimum in Mars and Gagat, respectively 2-5 and 2-6%. Variations in grain size indicators, amylose and protein content of varieties are weak in all varieties of special purpose, which testified to their high stability under growing conditions.
Highlights
Colored rice is consistent with the concept of food quality while meeting the demand for foods that improve the nutritional structure of the population
In connection with the above, the purpose of the work was to study the genetic material of colored rice, developed at FSBSI Federal Scientific Rice Centre (Russia, Krasnodar) in relation to some technological grain quality traits and their variability in varieties grown in the valley agrolandscape zone of Krasnodar region in 2017 - 2019 as donors of valuable traits of grain quality for breeding varieties of the functional purpose
The relevance of long-term studies of quality traits of special-purpose varieties with a colored pericarp is determined both by the tasks of developing products of high nutritional value, and by starting breeding programs for developing rice varieties of a functional direction and the development of optimal modes of their cultivation in production
Summary
Colored rice is consistent with the concept of food quality while meeting the demand for foods that improve the nutritional structure of the population. Many scientific works have shown the high nutritional value of rice with a colored grain pericarp [1]. In patients who ate black rice, plasma antioxidant status increased and inflammation decreased. Animal studies have shown a beneficial effect of consuming the colored fraction (pericarp) of rice grains in controlling blood lipids and related diseases, helping to prevent cardiovascular problems, which has been linked to various mechanisms, including increased antioxidant capacity in the body (Ling et al , 2001), a decrease in the total concentration of cholesterol in the blood (Xia et al, 2003), a decrease in the ratio between LDL cholesterol and HDL cholesterol (Ling et al, 2001; Xia et al, 2003) [2]
