Notes
Heterosis is defined as increased vigour of hybrids in comparison to their parents. In this study, seven cultivars of upland inbred rice (male parents) and their F_1 hybrids generated by crossing with a thermo–sensitive genic male sterile (TGMS) 103^S line (female parent). The cultivars were examined for characters of photosynthesis and dry matter production under drought stress at flowering stage and recovery at ripening stage. The results showed that under drought, all F_1 hybrids exhibited very low negative heterosis for CO_2 exchange rate, stomatal conductance, mesophyll conductance and transpiration rate, but high positive heterosis for intercellular CO_2 concentration. The heterosis value increased much more in the F_1 hybrids under drought recovery than under well–water conditions. During drought stress, heterosis value decreased slightly for dry matter accumulation compared to well–irrigated conditions. Although CO_2 exchange rate significantly decreased, dry matter accumulation was maintained in all F_1 hybrids after drought recovery, which suggests the potential for using upland rice as male parent to produce F_1 hybrids from TGMS lines for drought tolerance.
