The breeding program involves new objectives and approaches for adapting to changing climatic conditions by creating productive varieties with increased tolerance to drought. The aim of research is the evaluation of the germplasm through observations and measurements to choose valuable resources of initial breeding material. Were analyzed 20 accessions. The studied genotypes can be grouped into three categories from precocity point of view, difference between the earliest variety, Kerestelny (28.04) and the latest, Luna (25.05) was 27 days. The abundance of vegetative shoots was combined with the abundance of generative shoots, to break the existing negative correlations between seed production and DM production. Regarding plant height a large inter-varietal and intra-varietal variability was found, with average values above 100 cm in the varieties: Krasnodarska 115.2 cm and with values below 50 cm in the Luna variety 48.5 cm. The most resistant genotypes to Puccinia.sp. with the frequency of over 80% resistant plants are: Luna: 90%, Bronson: 89.5%, Prolate 86.7% and the most sensitive are Szarkad 5: 20% and Bull 20.5% unattached.
