| Summary: | The study was conducted during the period 2013-2014. Three Turkish (Denep, Efe, Gala) and four Italian (Baldo, Creso, Roma, Puma) rice variety used in the country are explored. During the growing season it is applied the standard agrotechnics of rice cultivation in Bulgaria.The samples were evaluated on morphological, biochemical and economic qualities according to international descriptors: vegetation period, paddy yield, length of panicle, weight of a panicle, mass of 1000 grains, total number grains in panicle, empty grains, crude protein, lysine. The indicators that are characterizing the productivity of varieties vary significantly at greater extent than those with quality. There are established positive correlations between the total number of grains in a panicle of rice production (r = 0.713), the weight of a panicle (r = 0.715) and the number of empty grains (r = 0.809) and negative with crude protein contents (r = -0.700). Radiated are varieties to be included in breeding programs as sources of valuable economics signs |
