White rust or white blister disease caused by oomycete fungi, Albugo candia is one of the major devastating rapeseed mustard. Continuous emergence new races pathogen responsible for breaking down resistance already existing resistant cultivars. So there need evaluation cultivars as well Brassica to find out stable sources against disease. In this context, 82 different genotypes, including 10 sp...

ABSTRACT In this study we evaluated the performance of potato cultivars in organic production system, aiming to identify those more productive and less damaged by Phytophthora infestans Diabrotica speciosa. The experiment was conducted during 2013/2014 2014/2015 crop seasons. Cultivars Ágata, Aracy Ruiva, Vitória, Clara, Eliza, Catucha Cris were assessed for severity area under disease progress...

Potato crops are susceptible to numerous field diseases causing significant losses in the quality and tuber yield. Control measures have a negative impact soil water resources affecting also farmers’ health food security. Hence, more sustainable agriculture management is need preserve ecosystems. Therefore, objective of this study was evaluate response nine potato cultivars (Fleur Bleue, Frisia...

ABSTRACT A random set of recombinant inbred (RI) lines (F2:7) derived from the cross of the inbred lines Mo17 (resistant) and B73 (susceptible) were evaluated for resistance to southern leaf blight (SLB) caused by Cochliobolus heterostrophus race O. The RI lines were genotyped at a total of 234 simple sequence repeat, restriction fragment length polymorphism, or isozyme loci. Field plots of the...

the objectives of the present study were to evaluate spring wheat recombinant inbred lines (rils) of diverse origin by estimating genetic parameters viz., variability, character association, cluster analysis, and principal component analysis (pca) for spot blotch resistance and yield components at bhu agricultural research farm during 2010-2011. grain yield per plot was significantly and positi...

ABSTRACT The use of host diversity as a tool for management of potato late blight has not been viewed as promising in the past. But the increasing importance of late blight internationally has brought new consideration to all potential management tools. We studied the effect of host diversity on epidemics of potato late blight in Oregon, where there was little outside inoculum. The experimental...
