EFFECT OF LIGHT AND TEMPERATURE ON VARIETAL RESISTANCE OF WHEAT TO PUCCINIA GLUMARUM ERIKSS. & HENN

Lu A Acta Phytopathologica Sinica 1958

Other claims from this paper (15)

Mechanism Variation in greenhouse light and temperature caused unstable wheat varietal reactions.
Observation Temperature was the most important environmental factor in variable wheat stripe rust reactions.
Association Wheat varieties became more resistant to stripe rust as temperature rose from 10℃.
Observation The critical temperature for transition from susceptible to resistant differed by variety and rust race.
Observation Eight of 60 variety race combinations switched from susceptible to resistant at 15℃.
Observation Fifteen combinations switched at 20℃.
Observation Eighteen combinations switched at 25℃.
Observation Sixteen combinations remained resistant across temperatures.
Observation Ycnta 1885 remained susceptible throughout light treatments.
Association Other susceptible varieties reacted specifically to light intensity and illumination duration.
Observation Race Y6B severely diseased Pima strains at 10°—20℃.
Observation Race Y6B could sporulate at 25℃.
Observation Race Y6 resembled Y6B in pathogenicity on six differential hosts.
Association The findings correlated with widespread breakdown of Pima 1 stripe rust resistance since 1955.
Observation Early Premium, Naking 4197, Liyung 1 and Nungta 6 were highly resistant to Y6B.
