Virulence Pattern of Pyricularia grisea Isolates from Farmers’ Fields on Newly Released Upland Rice Cultivars
The virulence pattern of the isolates of Pyricularia grisea from commercial fields of the upland rice (Oryza sativa) cultivars ‘Primavera’ and ‘BRS Bonança’ was analyzed. A hundred and seventy monoconidial isolates of the pathogen virulent to ‘Primavera’ and 139 to ‘BRS Bonança’ collected from eight fields, during two years (2001-2003) were tested, under greenhouse conditions, on six newly rele...
متن کاملVirulence and rep-PCR Analysis of Pyricularia grisea Isolates from Two Brazilian Upland Rice Cultivars
The phenotypic and genetic diversity of 77 isolates of Pyricularia grisea collected from two upland rice cultivars, Maravilha and Primavera, was studied. Isolates exhibiting compatible reaction to cv.Primavera were incompatible to cv.Maravilha and vice versa, with the exception of six isolates that were compatible to both cultivars. The virulence of isolates from cv. Maravilha on 32 test genoty...
متن کاملCharacterization of a Pyricularia grisea population from Uruguay by molecular analysis.
Blast disease, caused by hemibiotrophic fungus Pyricularia oryzae Sacc. (teleomorph: Magnaporthe oryzae (Hebert) Barr.), previously known as Magnaporthe grisea, is the most serious disease of rice and causes high yield losses in most rice growing regions every year. Blast is an endemic disease in all Iranian and Uruguayan rice fields, with yield losses up to 90 % that has been reported from som...
متن کاملComparative analyses of genomic locations and race specificities of loci for quantitative resistance to Pyricularia grisea in rice and barley.
Comparative genomic analyses have revealed extensive colinearity in gene orders in distantly related taxa in mammals and grasses, which opened new horizons for evolutionary study. The objective of our study was to assess syntenic relationships of quantitative trait loci (QTL) for disease resistance in cereals by using a model system in which rice and barley were used as the hosts and the blast ...
متن کاملThe UJI librarian robot
This paper describes the UJI Librarian Robot, a mobile manipulator that is able to autonomously locate a book in an ordinary library, and grasp it from a bookshelf, by using eye-in-hand stereo vision and force sensing. The robot is only provided with the book code, a library map and some knowledge about its logical structure and takes advantage of the spatio-temporal constraints and regularitie...
