Correlation between productivity traits forms of different origin perennial grass poa family

Abstract

Purpose is to identify relationships between different morphological and biological properties and economically valuable signs and allocation of valuable breeding material. Methods. Study on correlation of level interpopulation when using hay was carried out on samples that were allocated by the complex agronomic traits: Dactylis glomerata L. s. Drogobythanka, s. Dainava, Lolium perenne L. s. Drogobythskiy 16, № 716, № 3477, Phleum pretense L. s. Pidgyrianka, № 2806, Festuca rubra L. № 1009, № 1007, № 1008. Results. In the selection of plants Dactylis glomerata L. to raise and forage productivity features to be used length and seed of grains and in and seed weight ear. Between grounds productivity Lolium perenne L. there is a positive correlation, which is determined by the tightness in the complex hierarchy of relations with the resulting feature, varietal characteristics, duration of the growing season. Selection of varieties Pidgyrianka Phleum pretense L. to improve forage productivity can be made on the basis of plant height and cover of leaves In between samples Festuca rubra L. signs number of grains in the inflorescence and grain yield positive correlation was average, the correlation coefficient r = 0,47-0,73. Selected samples can serve genetic resources in breeding programs to create high-yielding varieties of integrated use. Conclusions. Established relationship between forage and productivity and their elements to interpopulation equal signs productivity in samples Dactylis glomerata L., Lolium perenne L., Phleum pretense L., Festuca rubra L. Revealed that productivity is closely correlated with indicators such as the structure of panicle weight, ear, Sultan; of generative shoots in the bush; weight of 1000 grains and in panicle, ear and sultans.
