Modified speed breeding approach reduced breeding cycle to less than half in vegetable soybean [<i>Glycine max</i> (L.) Merr.].

ABSTRACT: Vegetable soybean [Glycine max (L.) Merr.] is gaining popularity because of its high nutritive values and health benefits; however, its productivity is scarce. Recognizing the need to accelerate breeding progress, a modified approach of 'speed breeding' was used in 16 vegetable soybean genotypes to reduce the breeding periods. The genotypes were exposed to cycles of 10 h light (30 °C) and 14 h dark (25 °C) with CO₂ (550 ppm) and without CO₂ supplementation under the light intensity of 220 µmol m^-2 s^-1 at the canopy level and 70-80% relative humidity. To reduce the time further, physiologically matured pods were harvested once they changed their color from green to greenish yellow and dried in the oven for 7 days at 25 ± 2 °C with RH 10-20%
