Konyk H. Inheritance of productivity traits, development of breeding methods and creation of perennial grasses varieties for the zone of Carpathians

A research object is features of inheritance of economic-valuable signs Pleum pratense L.; conformities to law of display of intercommunications of the productivity with different quantitative signs in the process of cross-correlation analysis of simple of perennial grasses; creation on the basis of these conformities to law of new genotypes and variety. A purpose is creation of variety for the area of Carpathians and new feedstock;selection of valuable genetic sources; exposure of genetic nature and character of inheritance of economic-valuable signs; development of methods of selection; improvement of realization of elements of their genetic potential. Research methods - scientific and special agronomical (visual, instrumentation - gravimetric, matematicheski- statistical, genetic, cross-correlation, calculation-comparative).Difficult genetic determinaciyu of signs of the productivity of Pleum pratense L.:scientifically grounded new and the existent methods of selection are improved at creation of new feedstock and variety; well-proven efficiency of selection with the use of unlines of morphological marker signs on the basis of cross-correlation analysis at creation of feedstock. 4 variety of perennial grasses are created, from them three it is brought to the State register of variety of plants, suitable for distribution in Ukraine. As a result of study the author of introduktion 355, 347 standards of perennial grasses certification. By the methods of hybridization, selections, mutageneza, a new feedstock is created (452 hybrid populyacii, 268 plant-breedings numbers, 19 mutantnikh forms).The developed methods of selection and technology of their realization are used in plant-breeding practice of other scientific establishments. The developed and improved elements of seed production are inculcated of perennial grasses economies of Lvov obl. Industry of the use is the breeding scientific establishments and agricultural production.
