%X in the base technological scientist unit £¿los palacios£¿ seeds first generation of harvested rice isogenic lines, coming from f2 in vitro anthers culture from crossings amistad¡ä82/2077, 2077/amistad¡ä82, amistad¡ä82/ir759-54-2-2 and moroberekan/amistad¡ä82, were sowed in field, with the objective to evaluate their behaviour in natural blast field infection. the absence of dominant genes in heterocigosis involved in the inheritance to blast was confirmed and, apparently, the behaviour could be governed by major genes in homocigosis and small genes with additive effect. four isogenic lines wit good agronomic behaviour and blast resistant were selected. the same will be very useful to obtain new varieties.
