dc.description.abstractPrevashodni cilj istraţivanja u disertaciji bio je sakupljanje genetiĉkih resursa maĉijeg repa (Phleum pratense L.), karakterizacija sakupljene germplazme po agronomskim i biološkim svojstvima i ocena vrednosti sakupljenih populacija maĉijeg repa sa razliĉitih lokaliteta iz Zapadne Srbije u odnosu na već priznatu sortu K-41. Na osnovu analize varijanse evidentno je da su genotip i godina imali statistiĉki znaĉajan uticaj na prinos semena po biljci kod sorte i ispitivanih populacija Phleum pratense L. Genotip autohtonih populacija maĉijeg repa sa najvećim proseĉnim prinosom semena po biljci maĉijeg repa u 2009. i u 2010. godini bio je 20/Carina (0,0293 g i 0,0395 g). U 2010. godini ispitivane autohtone populacije maĉijeg repa imale su veći prinos semena po biljci, za 0,0102 g odnosno za 34,81 % u odnosu na 2009. godinu. Sorta K-41 imala je zadovoljavajući prinos i kvalitet zrna. Analizirajući većinu ispitivanih osobina autohtonih populacija Phleum pratense L. evidentna je meĊusobno pozitivna veza, osim posmatrane osobine BEM (bezazotne materije) koja je u negativnoj korelaciji sa svim osobina izuzev visine biljaka. Jake pozitivne korelacije uoĉene su izmeĊu osobina 1-2 (VB-DL), 1-3 (VB - ŠL); 1-4 (VB-PL),1-13 (VB-RBIO), 2-3-4 (DL-ŠL-PL), 2-13 (DL- RBIO); 3-4-5 (ŠL-PL-BL), 6-7 (DM- BS/M), 6-12 (DM- VPC), 7-8-9-11-12 (BS/M- MHS- BI/B- VPC- DC), 10-11-12 (VPM– VPC- DC); 14-15 (PSM/B– PSM/B). Uoĉava se da osobine: 1-VB-visina biljaka, 2-DL-duţina lista i 3-PL-površina lista imaju najveći selekcioni znaĉaj, jer su najjaĉe povezane sa drugim osobinama Phleum pratense L. Selekcijom ovih osobina će se postići povećanje vrednosti drugih osobina. Negativne korelacije uoĉene su izmeĊu 6-8, 6-9, 13-16, 14-16, 15-16, odnosno (6-DM-duţine metlice i 8-MHS- mase 1000 semena); (6-DM-duţine metlice i 9-BI/B-broja izdanaka po biljci) (13- RB-regeneracije biljaka i 16- MSMI- mase suve materije izdanaka)Rezultati ove disertacije su znaĉanjni i iz razloga što su se identifikovali superiorni genotipovi sa dobrim osobinama u datim ekološkim uslovima i visokim prinosima po jedinici površine, dobrog kvaliteta suve materije. Kao dobra osnova za dalji oplemenjivaĉki rad pokazale su se sledeće populacije: 2, 16, 19 i 20. Ovi genotipovi mogu da budu donori pojedinih gena za pojedine osobine i od njih se mogu proizvesti kvalitetnije hibridne kombinacije.sr
dc.description.abstractThe primary goal of research in this thesis was to collect genetic resources thimoty grass (Phleum pratense L.), characterization of the collected germplasm agronomic and biological properties and evaluation of the value of the collected population thimoty grass in the various regions of West Serbia in relation to the already recognized variety K-41. Based on the variance analysis, it is evident that the genotype and year had a statistically significant influence on seed yield per plant in the examined populations of Phleum pratense L. Genotype of autochthon thimoty grass populations with the highest average seed yield per plant in 2009 and in 2010 it was 20 / Carina (0.0293 g and 0.0395 g). In 2010, the test of autochthon thimoty grass had higher seed yield per plant, for 0.0102 g respectively to 34.81% in relation to 2009. The K-41 variety had the crude protein content higher than all tested populations. Analyzing most of the investigated properties of autochthon populations of Phleum pratense L., there is evidently a positive relationship, with the exception of the observed properties of BEM (harmless matter), which is in a negative correlation with all the properties except the height of the plants. Strong positive correlations were observed between properties 1-2, 1-3,1-4,1-13,2-3-4, 2-13, 3-4-5, 6-7, 6-12,7-8 -9-11-12,10-11-12,14-15. It is noted that 1- plant height, 2- length of leaves, 3- leaf surface has the highest selection importance, because it is most strongly associated with other properties of Phleum pratense L. By selecting these properties, an increase in the value of other properties is achieved. Negative correlations were observed between 6-8, 6-9, 13-16, 14-16, 15-16, respectively (6- panicle length and 8- average weight 1000 seeds); (6- panicle length and 9- number of plants per plant) (13- regeneration and 16- average weight of dry matter). The results of this dissertation are important because they have identified superior genotypes with good properties in given ecological conditions, and high yields of good quality of dry matter. The results of this dissertation are important because they have identified superior genotypes with good properties in given ecological conditions, and high yields of good quality of dry matter. Populations 2, 16, 19 and 20 proved to be a good basis for further breeding work. These genotypes can be donors of certain genes for individual traits and they can produce better hybrid combinations.en
