Konstantin Kamishev, Svilena Tosheva

Abstract: During the period of 2010 – 2011 year in IPGR “K. Malkov”, Sadovo the productivity possibilities of 13 Bulgarian rice varieties were estimated in comparison with the controls – Osmandzhik 97, Krasnodarski 424 and average trail standard. They were also evaluated by lodging resistance and vegetative period. It was established the genotype had the prevailing influence (85.84%) on the yield variability. Proved highest yield showed IRGR Viki – 1130.75 kg/da, Avalya – 1100.25 kg/da and Iskra – 1080.25 kg/da. The exceeding toward the highest yielding standard Osmandzhik 97 was 21.36%, 18.08% and 15.94%, respectively. Avalya and Miziya combined high yield and short vegetative period. All high yielding Bulgarian varieties were characterized with very strong lodging resistance.
