초록

This study was conducted to obtain basic information on mainstem, branch and leaf characteristics related to canopy
for development of high yielding cultivar using 70 Korean soybean cultivars developed from 1913 to 2000. Variations of canopy
width, branch length, and canopy width/length ratio were higher compared to other characteristics among 12 mainstem and branch
characters. Variations of petiole angle, leaflet width/length ratio and compound leaf dry weight were higher than other
characteristics among eight leaf characters related to plant canopy. Three classifications of soybean cultivars were used based
on usage: I)soy sauce and tofu, II)bean sprout, and III)cooking with rice. Canopy width/length ratio was higher in group III,
cooking with rice than group I, soy sauce and tofu, and group II, bean sprout, and there was no difference between the two,
group I and group II. The total branch length/main stem height ratio was higher in group II, bean sprout and group III, cooking
with rice than group I, soy sauce and tofu. Mainstem and branch characteristics related to plant canopy were classified into four
groups by ratio of canopy width/length and total branch length/main stem length, respectively. Soybean cultivars with narrow
canopy and high dependence of mainstem were Danweonkong, Keumkangkong, Shelby, and Shinpaldalkong. Soybean cultivars
with broad canopy and high dependence of mainstem were Kanglim, Keumkangdaelip, and Jinyulkong, and a cultivar with broad
canopy and high dependence of branch were Geomjeongkong 2. Leaflet length/width ratio was lowest in cooking with rice and
there was no difference between soy sauce and tofu and bean sprout. Compound leaf area was largest in cooking with rice and
smallest in bean sprout. Leaf petiole length was short in bean sprout and there was no difference between soy sauce and tofu
and bean sprout. Leaf petiole angle was highest in cooking with rice and lowest in bean sprout. Leaf type was classified into
four groups based on leaflet width/length ratio and compound leaf area, respectivly. Buseok and Taekwangkong had an oval
leaflet and largest area of compound leaf. Eunhakong and Sohokong had extreme narrow leaflet and smallest area of compound
leaf. Leaf petiole type was classified into three and four groups based on leaf petiole length and angle, respectively. A soybean
cultivar with the shortest petiole length and smallest petiole angle was Eunhakong and cultivars with short petiole length and
large petiole angle were Alchankong, Muhankong, and Pureunkong. A soybean cultivar with long petiole length and small petiole
angle was Sinpaldalkong 2. Among a total of 70 Korean soybean cultivars, Eunhakong had an extreme narrow type in leaf,
smallest compound leaf area, shortest petiole length, and smallest petiole angle of compound leaf.
