Nekompletna otpornost prema Puccinia recondita tritici nekih sorti pšenice

Abstract

Ispitana je nekompletna otpornost domaćih i stranih sorti pšenice u poljskom ogledu i kontrolisanim uslovima u stadijumu sejanaca prema Puccinia recondita tritici. Materijal je diferenciran na osnovu intenziteta zaraze, vrednosti AUDPC, dužine latentnog perioda 50, uspešnosti infekcije i LP 50x100/IE.

A group of very different wheat genotypes, twelve from nine countries from all over the world and seven from Yugoslavia, were tested in a field trial located in Rimski Šančevi. ‘The infection intensity of Puccinia recondita tritici was estimated on the basis of areas under disease progress curve (AUDPC). Latent period 50 (LP 50) and infection efficiency (IE) of the leaf rust culture in the type of race 77 were determined in growth chamber (15°C, day-night 16/8 hours, humidity over 80%).
