Abstract

In order to understand the changes in yield, harvest index (HI) and biomass of aboveground parts of rice, 33 japonica rice cultivars released from 1958 to 2005 were planted. During the 47 years, the grain yield increased from 9 11836 to 15 0601 kg/hm2 and HI from 046 to 055 in the genetic improvement of rice, with the average annual growth rates of 139% and 044%, respectively. In the genetic improvement, the total number of tillers per plant decreased, and the biomass per unit area slightly increased at the harvest stage. The increases of yield and HI resulted from increased biomass of effective tillers and single plant, and the increase of single plant biomass was related to increased biomass of different organs during the genetic improvement. The stem and sheath biomass at heading and the leaf biomass at 30 d after heading showed the biggest increase, up by 7517% and 4994%, respectively. The biomasses of leaves and stem sheath at 10 d after heading, and single plant biomass at 30 d after heading were obviously correlated with the yield. The results indicate that the genetic improvement has resulted in the increase of yield and HI. This increase is correlated with the decrease of total tiller number per plant, and increase of biomasses of effective tillers and single stem. The leaf biomass after heading and the stem and sheath biomass at 10 d after heading can be used as a selection criterion of high yield cultivars.

Key words： rice; genetic improvement; biomass; yield; harvest index
