Forty-four F1 hybrids derived from crosses among eleven temperate japonica rice cultivars were grown and evaluated for traits related to cold tolerance including days to heading and spikelet fertility in the cold-water irrigated plot (17oC) and the control plot. Cold water treatment had highly significant influences on all traits measured in the parents and F1 hybrids. Significant positive correlation (r=0.58**) was observed between culm length and spikelet fertility in the cold water plot whereas poor correlation (r=0.25) was detected between spikelet fertility and culm length in the control. This finding indicates that spikelet fertility is affected by culm length and the cold water depth in the cold-water irrigated plot. The amount of heterosis showed variation from trait to trait. Fertility showed the highest heterosis among the five traits in the cold-water irrigated plot. In contrast, all the traits except for panicles per plant displayed negligible heterosis in the control plot. Sizes of heterosis under both field conditions were compared. In the cold- water irrigated plot midparent and better parent heterosis for spikelet fertility and heading date and midparent heterosis for culm length were significantly higher than those in the control. For panicles per plant, in contrast, midparent and better parent heterosis were significantly higher in the control than that in the cold-water irrigated plot. Our observation that heterosis can be expressed under low temperature conditions supports the idea that japonica hybrids can be grown in low temperature-prone areas where the limited growing period due to low temperature poses a ceiling on the cultivation of productive, cold-susceptible and medium-to late maturing japonica cultivars.
