HIGHLIGHTING GENETIC PROGRESS IN IMPROVING WINTER RYE

Abstract

This paper highlights the contribution of winter rye culture, initially by testing and identifying the most suitable local populations and foreign varieties, and subsequently through the creation, introduction and widespread in the production of Gloria, Orizont, Ergo and Suceveana varieties, obtained at  A.R.D.S. Suceava. During the 1951-1955 stage, certain local landraces and the cultivar Petkus registered an average yield on 1300 kg/ha, and during period 1970-1975 the average yield of the cultivars Danae and Dankovskie Zlote grows at the 3160 kg/ha. The cultivars Danae, Dankovskie Zlote and Ianoşi during period 1976-1985 registered an average yield on 4207 kg/ha, and during 1986-1995 the cultivars Gloria, Ergo and Orizont which were created at the A.R.D.S. of Suceava had an average yield on 4980 kg/ha. The cultivar Suceveana  was cultivated during  1996-2005, with an average yield on 5075 kg/ha. The superiority of the four cultivars: Gloria, Orizont, Ergo and Suceveana from the productivity and yield stability  point of view ,was statistically demonstrated through the distribution of the correlations and variance of productions in comparison with the standard cultivars from the above periods. The superior values of the quality traits recommend the utilization of the rye cultivars which were created both for bread making feature and for fodder users.
