Abstract
- Nowadays the species Triticosecale has started to gain ground in Banatului Plain and in Romania, mainly due to the increased yields of biomass and grains in comparison with other cereals and due to the high adaptability to different climate and soil conditions. Triticale is interesting for inbreeding due to its features mainly as fodder plant. Triticale proved during time that it is sensitive to the attack of the cereals pathogens. In Banatului Plain triticale is sensitive to the attack of the fungi Puccinia striiformis (yellow stripe rust) and Drechslera tritici repentis (tan spot). In Banatului Plain tan spot appears in every year, but yellow stripe rust isn't appearing yearly due to its demand for special conditions of temperature and moisture. This research is a case study developed in the spring of year 2018 when climate conditions were favourable to the development of the fungus Puccinia striiformis. Thus, there was monitored an experimental filed comprising nine lines and one variety of triticale in conditions of natural infection. There was evaluated the resistance to this dangerous pathogen of the cereals. The biological material used was: KT 1430 - 10, KWT 13069, 202.567, KT 390, 10T70126, 08TF01, 141 TRICAL, WINTER MAX and TM 01. Attack severity was comprised between 10% (line 10 T 70126) and 90% in line 202.567 that had proved to be the most sensitive from entire experimental field. Frequency of the plants with symptoms was maximal in five triticale lines from experience (F = 100%). Winter Max variety was highlighted by a low attack frequency of 5% plants with symptoms, the lowest from the experiment. All the analysed genotypes were reacted differently to the pathogen attack. Five triticale lines have manifested high sensitivity (FS) to the attack of Puccinia striiformis. Triticale lines 08TF01 and 141Trical and the variety Winter Max have manifested a reaction of sensitivity to the pathogen (S). Moderate resistance was noticed in only one triticale line from experimental field, respectively the line 10T70126. [ABSTRACT FROM AUTHOR]
