The results suggested that, the introgression lines showed extensive changes, compared with the recipient R122, in biological traits, such as plant type, plant height, growth duration, tillering ability, spikelet setting density, grain shape, apiculus color, blast resistance, rice quality, restoring ability and storability characters.
