Genetic progress in the Romanian triticale breeding program
Ittu Gheorghe*, Saulescu Nicolae, Ittu Mariana, Mustatea Pompiliu and Marinciu Cristina

Since 1984 yield raised up to 43 kg / ha¹ and year¹ or 0.74 % /year¹ this progress being achieved mainly by improving fertility of spikes, plumpness of kernel, the test weight and introduction of short straw RhtB1b (Rht1) and Ddw1 (Hl) genes. In order to improve the yield stability, under predictions of global climatic changes, improvement of genetic diversity to powdery mildew, leaf and yellow rusts, virus and spike diseases and also for pre-harvest sprouting are still demanded.

A non-destructive method to assess changes in the biomass of small-grain cereals under field conditions
D. Villegas1, J. Lozano2 and C. Royo1

The poster describes a non-destructive method to assess biomass based on remote sensing techniques. This method is suitable for field phenotyping and it is useful to assess biomass evolution as well as to estimate radiation use efficiency.

Genetic integrity of rice seeds during ageing and gene bank storage by SSR analysis
I. O. Daniel, K. A. Adeboye, O. W. Adabale, E. S. Aladele and A. Boerner

Rice seeds loose germination capacity with ageing. Loses in genetic integrity was found to occur during artificial ageing at a time when percentage germination declined to 54%.

Characterization of nitrogen use efficiency in a winter wheat collection
István Monostori, Tamás Árendás, Fruzsina Szira, Gábor Galiba, Borbála Hoffmann, Attila Vágújfalvi

The first-year dataset of the three year experiment has been analysed. To find out, which genotype is recommended for intensive and which one is for extensive cultivation, the performances of the varieties were characterized under low and also under favourable nitrogen supply. The varieties were also ranked based on the increased level of their performance due to the nitrogen supply. Correlations between the measured phenotypic data and the NUE parameters were also calculated.
