Title:
Breeding studies on node number and internode length of soybean. (I). The pattern of association between internode length, pod number per node and other yield components
Publication date:
1984
Summary:
To estimate the environmental effects on character expression in soybeans, five long-internode and seven short-internode varieties were tested in the spring and fall crop seasons at Taichung, with three planting densities (45 x 20 cm, 45 x 10 cm, and 45 x 5 cm) and three levels of nitrogenous fertilizers (0, 60, and 120 kg/ha). The plants were recorded with respect to internode length (cm) on the main stem, mean pod number per node, seed yield (g/plant), 100-seed weight (g), and pod number per plant. The data showed that the genotype-environment interactions were significant to all characters except for internode length. The internode length increased with planting density except in the fall crop. Other characters reduced as the planting density increased. Internode length enhanced as the level of nitrogen application increased except in the fall crop. The phenotypic correlations among internode length, pod number per node and yield-components differed according to planting seasons, densities, and nitrogen levels. Results indicated that soybean breeding would be aimed at short-internodes.
