Abstract:
Corn is a food crop that has an important role both in industries and as a staple food in many countries throughout the world. Its growth, development and productivity seriously affected by drought. An experiment was carried out to investigate the effect of drought stress on sugar and proline content of eighty maize genotypes raised by half diallel crosses under irrigated and partial irrigated conditions in randomized block design (RBD) with two replications. Proline and sugar content was analyzed to assess the performance of genotypes in respect to drought tolerance. Increase in the level of sugar and proline content among genotypes was found highly significant at 1% probability level. Among eighty maize genotypes, genotypes IL1XIL4, IL3XIL5, IL2XIL5, IL2XIL11, IL7XIL11, IL9XIL10, IL8, IL5XIL11, IL1XIL7 and IL1XIL8 displayed increased values of sugar and proline content. Hence may be considered as drought tolerant and may be employed in crop improvement programme in future.
