Abstract

Breeding for drought resistance in peanut can reduce aflatoxin contamination. It is also a sustainable strategy to improve both crop productivity and peanut quality under drought conditions for use as a raw material in peanut industry. Peanut breeding program for drought resistance is ongoing at the Faculty of Agriculture, Khon Kaen University. The research project aimed to generate the integrated knowledge about 1) drought resistance mechanisms based on the responses for physiological and morphological characters and 2) the information on the inheritance of drought resistance in peanut. The information obtained will support the peanut breeding program for a more rapid progress in the selection schemes. The project has tested the peanut lines under drought conditions that can occur at all peanut growth stages including early season drought, mid season drought, late season drought and long term drought. The project could identify drought mechanisms and provide the information on the inheritance of drought resistance that will be useful for planning peanut breeding programs for drought resistance. The information can be used for designing breeding strategies for more effective breeding programs. The project was initiated since 2002. As a result of the project, twelve new researchers (5 master degree students and 7 PhD students) have been trained. The collaborative net work was set up and more than 30 publications have been published in the international scientific journals. The research papers have been cited more than 105 times. The further investigations will be focused on 1) the metabolic pathways of adaptation to drought 2) the use of simulation models to predict the responses of roots to drought and 3) the responses of roots to late season drought.
