A large number of sterile spikelets were induced by low-temperature at the booting stage of rice plants during the middle to the end of July in 1988. The authors investigated various aspects of occur...
Relationships between days after sowing to heading (DAS-H) and dry matter yield of main stem, between DAS-H and dry matter yield-related traits involving total leaf number, number of elongated intern...
Eleven kinds of rice seedlings with different plant age in leaf unmber in the range 0-7.2 (counting the incomplete leaf as the first leaf), raised under the same condition, were grown in the phytotron...
Appropriate plant height, tiller number and heading date are important traits for maximizing rice production. In order to understand the genetic basis of the relationships among these three plant trai...
Genotype×environment interactions of heading date and culm length in rice were estimated for cultivars with high palatability. Genotype×year, genotype×location, genotype×amount of fertilizer and genot...
Rice palatability correlates with amylose content, which correlates with heading date, showing that indirect selection through low amylose content for high palatability usually results in predominan...
The constancy of the heat unit accumulation needed for the heading of sorghum cultivar P956 was examined for the simple heat unit accumulation method, the effective heat unit accumulation Method I in ...
Paddy rice seedlings transplanted at different growth stages in Miyagi prefecture in 2003 were examined for heading date and the percentage of ripening on all stems in each hill in relation to cool su...
