Yield and some morphological properties of newly introduced Italian rice varieties grown in Macedonia

This paper presents the results of investigation of three newly introduced Italian rice varieties Brio, Ellebi and Opale , in comparison with two standards P rima riska and R-76/6 . The field experiment (randomised block system) was conducted during 2010 and 2011 under the agro-ecological conditions of Kocani region. The paddy rice yield, stem height, panicle length and number of productive tillers per m 2 were analysed. In both years of investigation, the paddy rice yield of the standard variety R-76/6 as well as the introduced Brio , Ellebi and Opale varieties was significantly lower compared with standard P rima riska variety. Тhe stem height of the Italian rice varieties was significantly shorter in comparison with standard varieties, in both years of testing. In general, according to the results obtained in this investigation, the newly introduced varieties: Brio , Ellebi and Opale could be included in the rice breeding programmes, especially for breeding short stem rice varieties.
