理想型 小麥品種育成을 위한 生理生態的 形質構成에 關한 硏究

Studies on the Physio-ecological Components for Improvement of Ideo-type Winter Wheat

This study was conducted to clarify the composition of the physiological and ecological components for improving ideotype of wheat. Ideotype of ecological characteristics of wheat will be desired to recombine early maturity, two semidwarf genes with erect plant type about 70~80㎝ height, less stem elongation by late spring, long spike, many spikes per ㎡ and many grains per spikelet. Also, physiolo gical ideotype of wheat will be desirable to recombine 6.4~6.8 of LAI, high chlorophyll content from regrowing period to April 21 (total 15.0~18.9), after that slightly even after heading, high NAR (9.5g/㎡/day), 40~48 percentages of dry weight ratio for spike to stem and leaf brade with good plant type.
