Abstract


Abiotic stress is an alarming threat to the vegetable cultivation and drastically reduces the crop yield. Drought and flood are the two important abiotic stresses that occur more frequently in farm lands. They both combinedly results in heavy yield loss and causes more damage to crops. Among various stresses, drought stress is considered to be the major stress to plants. Seriousness of drought stress depends on its timing, duration and intensity. Flood is a crucial stress that is frequently witnessed in India because of the changes in rainfall pattern. So, improved varieties should be developed through various breeding strategies. Effective management techniques should be followed to tackle the stress conditions.
