TECHNIQUES FOR SCREENING CERCOSPORA LEAF SPOT RESISTANT FENUGREEK GENOTYPES

Cercospora leaf spot (CLS) caused by Cercospora traversiana is an important phyto-pathological problem of fenugreek (Trigonella foenum graecum L), a multiuse legume crop. Field screenings for resistant plants, although accurate and effective, demand significant time and a sizable workforce to accomplish the goal. Also, weather conditions in the field may not always be favourable for uniform disease spread which eventually may lead to failure of the overall experiment. Whole plant assays (WPA) and detached leaf assays (DLA) with artificial inoculation not only help in scaling up the number of plants screened but also reduce the space, time and the amount of inoculum needed for the experiment. The results from our two experiments indicate that both WPA and DLA methods can be used reliably to differentiate the resistant and susceptible genotypes of fenugreek. In addition, the correlation coefficient (r = 0.875, pThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
