Abstract:

Food security in the world is challenged by increasing food demand and provision of less supply mainly due to declining water availability. Maize is the third most important world cereal crop. It is one of the major components of human food and animal feed thus grown for both grain and forage purposes in human as well as livestock sector. The demand for maize has also increased significantly due to rapid development of poultry and animal feed industries. Combining ability analysis provides information for characters related to drought tolerance. Stem reserve can be exploited to combat water stress condition. To achieve this after 14 days of anthesis, plants were defoliated followed by complete plant surface bleaching by spray of commercial market bleach diluted with tap water 4 times solution. The total assimilation of photo-synthetase in the seeds was result of remobilization of reserves in different parts of the plant. The best combinations among diverse genotypes with good amount of stem reserve mobilization in the face of climate change and scarce water may be the best success to ensure food security and law and order throughout the world.
