Waterlogging Effect On Short Duration Soybean Genotypes: Phenology And Greenness

ABSTRACT: Stress condition alters the seasonal events and appearance of plants. A field experiment was conducted during January to April 2020 to evaluate the effect of waterlogging on phenology and greenness of short duration soybean genotypes. Twelve genotypes such as BD2334, G00113, G00164, G00067, G00221, BD2331, G00138, G00312, G00058, G00060, G00025 and BU Soybean-1 (check) were tested under 4-days of WL comparing with no WL (control). The experiment was laid out in a split-plot design with three replications. The results indicated that, WL stress reduced plant height and greenness while enhanced lodging. Genotype BD2334 and G00025 displayed better performance in terms of greenness under 4-days of WL stress, while other genotypes showed varying levels of response to WL. Genotype G00113 exhibited better lodging resistance under 4-days WL compared to other genotypes. As a whole, the soybean genotypes BD2334, G00025 and G00133 were found relatively WL tolerance concerning phenology and greenness Therefore, further research including those three genotypes is necessary at the field conditions for developing a WL short duration soybean variety.
