Characteristic of mutant forms sudangrass Sorghum sudanense (Piper) Stapf.
Irena Golubinova, Plamen Marinov-Serafmov, Ana Ilieva
Abstract: During the period 2011 – 2013 in the experimental field of the Institute of Forage Crops, Pleven under field conditions was studied 20 mutant forms Sudan grass originating in the from three varieties Kazitachi (Japan), Vercors (USA) and Voronezhskaya 9 (Russia) obtained by irradiation of seeds with γ-rays (Cs137) in the range of 200 – 300 Gy in 2008. An original characteristic of mutant forms obtained as a breeder signs importance and based on this created collection of 20 mutant forms possessing a set of signs and valuable biochemical characteristics, superior to the parents of more than one of the studied indication, which can be used successful in breeding programs in Sudan grass. Received new mutant forms of the three varieties Sudan grass, as M-200/286 and M-300/43 originating variety Kazitachi, M-300/69 and M-300/114 – origin Vercors and M-200/255 and M 200/256 – origin Voronejskaya 9 superior varieties starting with the best combination of a complex of economically valuable indicators.
The field trial, as a result of mutation breeding by Sudan grass confirms and demonstrates the potential of experimental mutagenesis to create genetic diversity in Sudan grass, resulting in a created collection of mutants possessing a number of important biological and economic properties and attributes.
