Study Drought Variability Resistant Forms of Species Festuca Pratensis within Used in Turf Mixtures

Abstract

In terms of combining aesthetics with utility, some species of perennial grasses are used to turf green spaces, sports grounds, slopes, the waste dumps, which require diversification of these species improvement directions. Important is obtaining new biological forms - varieties of main species of grass turf with increased resistance to drought during the summer increased land may represent an important objective of the research companies producing seed of this kind. Maintaining knowledge and genetic resources available is a foremost requirement for successful improvement activity. By hybridization to create new and original material makes an important source of variability in process improvement. The hybrid forms often show an increased variability compared with the parental forms from which they originate. The hybridization can be obtained transgression, which forms a hybrid cumulate grade attributes of the parents emphasized. Original material improvement to be maintained is divided in two categories at the beginning of works to improve existing (varieties, hybrids, lines, clones, local populations) and breeder material created by various methods conventional or unconventional (hybridization, inbreeding, vegetative multiplication, polyploidy, etc.). Achieving this goal requires the organization and the study of plant genetic resources collections as rich enough to be within the possible exploitation of genetic variability. Paper presents results that include studies of original material improvement in order to use valuable resources to create new synthetic varieties resistant to drought. To design a program to improve the species Festuca pratensis, need to consider and study the variability coefficient established between ecotypes, populations and species.
