Field experiment was conducted under the rice-wheat two-ripe systems at the Lixia River area during the year 2006–2007, three mid-season japonica rice cultivars including Yanjing 9 (small panicle type), Huaidao 9 (medium panicle type) and 9 you 418 (large panicle type) were adopted to investigate the effects of five planting densities on yield and quality of mechanical-transplanted rice. Results showed that with the increase of seedlings per hill, the final panicles per plant increased while the number of grains per panicle, the grain filling rate and the 1000-grain weight decreased; and the yield of three cultivars increased firstand then decreased. The highest yield was obtained when rice was transplanted with 4 seedlings per hill for small panicle type, with 3 seedlings per hill for medium panicle type and with 2 seedlings per hill for large panicle type. With the increasing of seedlings per hill, the chalkiness degree, the chalkiness rate and the amylose content increased while the milled rice qualities and the protein content decreased, and the gel consistency became longer. Among all of the RVA profiles, the peak viscosity, hot viscosity, breakdown, the final viscosity and the pasting temperature increased first and then decreased. The setback decreased first and then increased.Considering the grain yield together with quality, we suggest that for the coordination of high-yielding and high quality rice transplanting should be with 4 seedlings per hill for small panicle type rice, 3 seedlings per hill for medium panicle type rice and with 2 seedlings per hill for large panicle type.
