Abstract
Fourteen rice varieties originating from Italy (arsenal, nembo, ronaldo, galileo, sprint, ulisse, krystalino, mirko, sfera, gloria, pato, creso, vasco and san andrea) were grown in agro-ecological conditions in the Republic of Macedonia in 2014 and 2015, in order to evaluate the genetic variability for yield and some important yield-related traits, like number of panicles per m2, plant height, panicle length, number of grains per panicle, weight of grains per panicle and 1000 grains weight. Statistical analysis showed that phenotypic coefficient of variability was higher than the genotypic coefficient of variability for all evaluated traits. The highest values for genotypic and phenotypic coefficients were obtained for the number of grains per panicle (GCV = 48.51%; PCV = 55.02%) and plant height (GCV = 46.23%; PCV = 48.85%). High level of broad sense heritability for the plant height (89.57%), the number of grains per panicle (77.74%), panicle length (77.64%) and a number of panicles per m2 (59.44%) was observed. High level of heritability coupled with genetic advance was noticed for the number of panicles per m2, a number of grains per panicle and panicle length, which underscores the importance of these traits for the process of selection and improvement of rice genetics.
Key words: variety, genotypic and phenotypic variability, broad sense heritability
