Abstract:
Study for the genetic diversity of P. oryzae populations, under natural inoculation, trapping of virulence races present in ecosystems, was done during the period of 2008 to 2010 in two countries. One location/country was surveyed to highlight that resistance genes: Pi1; Pi11; Pi12; Pi19; Pib; Pi20; Pi5; Pi7; Pia; Pia+Pi19; Pia+Pish; Pif, Pii, Pik, Pik-p, Pish, Pit, Pit, Pita-2, Piz, Piz-t, Piks at M'be and and those at Ouedeme: Pi1, Pi12, Pi19, Pi1b, Pi3, Pi5, Pi7, Pia, Pii, Pik, Pi-p, Pit, Pita, Piks incidence. It was shown that they were overcome by a large proportion of the virulence gene of P. oryzae population. However, virulence genes that are capable of overcoming resistance genes: Pi33, Pi5 (t), Pi7, Pi9, Pikh+Pi-1+Pita+Pita, Pik-m ,Pish, Pitta-2, Piz-5, were absent or rare. These genes were effective against the pathogen population studied. This study also showed that Pi5 and Pi7, Pikh +Pi-1+Pita+Pita, genes association which were individually inefficient, has conferred a sustainable resistance to blast that was observed in Moroberekan and Tetep. This work will help rice breeders and plant pathologists to select rice varieties with durable resistance to blast disease.
