Plant breeding efforts have substantially increased yields mainly of crops grown under (near) optimum conditions, especially during the last half century. This, with or without deliberate efforts, has resulted in an increase in adaptability of cullivars and stability of grain yields, even in abiotic stress environments. In order to ensure nutritional security for the growing population, especially in the tropics with its dwindling and degraded land resources, we constantly need newer crop production tzchnologies. Even in highly developed temperate agricultural systems, 60 to 80% of the seasonal variation in crop productivity is attributed to weather fluctuations (Thompson 1975; Boye 1082). In the tropics where the intensification of crop production and extension of crops to more margrnal areas are the order of the day, iticrcased research on crop productivity, especially in stress environments is callcd for.
