Productivity of the New Grain Sorghum Variety Maxired

Abstract

Since 2002 in the Agricultural Institute – Shumen have been carried researches on a project for sorghum breeding. As a result a rich gene pool of fertile lines and perspective hybrids with different maturity, height and type of the panicles, grain colour, high productivity and combining ability has been created. In the present report are given the results of the productivity tests of the new grain sorghum variety Maxired. The Maxired variety is a hybrid of the pollinator SGR 0601 with the sterile line RS 28A. The pollinator is selected after individual selection by phenotype and combining ability. The sterile line RS 28A is received by the scientific exchange with Euralis Semences. The hybrid SG 0601 is with average late maturity, mean height, has symmetrical elongated compact panicle with red-brown grain colour. The results of the comparative tests situate the hybrid SG 0601 – Maxired variety in the list of the mean late maturity varieties with high productive potential during more continuous vegetation. After three years ecological tests in the system of the EAVT the Maxired variety is certified by the Experts Commission and is included in the National Varieties List.
