| Abstract: | Four Yunnan rice cultivars were crossed with two common cultivars and thegenetic variation in these crosses were observed. The F_2 progenies exhibited wide ranges ofsegregation in heading date, fertile spikes per plant, number of grains on main spike,percentage of fertile spikelets and 100-seed weight. There were large number of plants withlarge spikes and large grains in F_2 progenies of the crosses between Yunnan and commonrice varieties. |
