Dry matter production before heading and determination of number of spikelets of rice cultivar 'Takanari'.

摘要

Dry matter production and spikelet numbers of semi-dwarf indica rice cv. Takanari were compared with those of standard japonica cv. Kochihibiki in field experiments. The average above-ground dry weight at heading (DWh) of Takanari was 1108 g m-2 with a coefficient of variation (CV) of 7%, which was lower than that of Kochihibiki (11%). The average number of spikelets (Sp) of Takanari was 48400 m-2 with a CV of 5%, which was slightly lower than that of Kochihibiki (6%).
