Herencia de la resistencia al daño mecánico causado por Tagosodes orizicolus (Muir) (Homoptera-Delphacidae) en arroz Oryza sativa
In Colombia all rice varieties developed are reported as resistant to Tagosodes orizicolus. Given the narrow genetic base of the resistant sources, this study was undertaken to identify the resistant parents or donors more oftenly used in Latin America. The materials were characterized as resistant (Mudgo, Amistad 82, IRAT 120, IRAT 124, Makalioka) or susceptible based on the free chosen test and non chosen test and on the survival and oviposition of the insect (Chianan 8, Colombia 1, Bluebonnet 50, IR 8 (lCA), IR 8 (IRRI), Tetep and Cica 8). The damage was associated with insect survival, oviposition and eggs eclotion. To determine heritability two parents (Makalioka and Mudgo), were crossed with IR 8 F1 and F3 populations were also evaluated based on the free chosen test.
