Patogenicidad de Magnaporthe oryzae en variedades y líneas de trigo cultivadas en Paraguay

Abstract: <p>El brusone causado por <em>Magnaporthe oryzae </em>patotipo <em>Triticum</em> es uno de los problemas más serios para la producción de trigo en Sudamérica. Debido al número reducido de fuentes de resistencia, la identificación de nuevas fuentes es de suma importancia. En este trabajo se evaluó la reacción de las variedades de trigo sembradas en Paraguay a la infección por <em>M. oryzae</em>. Treinta y dos variedades y cuatro líneas avanzadas del Programa Nacional de… Show more

“…In the case of the lines from a cross Caninde 2/Milan, Caninde 2 is the progeny of a Paraguayan cross (ITAPUA35/ PF84432//CORDILLERA 4), deriving its gene pool from large and diverse sources. Itapua 35 (CMH74A.754//PEL72380/ ARTHUR 71) is a CIMMYT advanced line selected to incorporate an excellent level of field resistance to Stagnospora nodorum blotch from Brazilian germplasm Pel 72380 and Arthur 7, and was also classified as moderately susceptible to wheat blast infection (Chavez and Kohli 2018); Cordillera 4 (MN 72131 = AEPOGLOM/II64.27) is an advanced line from Minnesota, USA, introduced to incorporate leaf rust resistance from an unknown source from Russia (Aepoglom) and PF 84432 is a Brazilian advanced line (LD*2/ALD//2*HAD/7/ALZ110/2*IAS54/6/TP/4/TZPP/SON64//NAPO/3/CIANO /5/ PEL 11319-61// IAS20/ND81 (PF6968), developed for an overall excellent resistance to wheat diseases. It must be pointed out that several parents of this line, Londrina, Hadden, Alvarez 110, Toropi, Tezanos Pintos Precoz (TZPP) and PF 6968 etc., have been widely used in the Southern Cone region and globally, for carrying resistance to multiple diseases of wheat.…”
