abstract

  • There are two options for the management of crops in water l imi t ing environments: theagronomic and the genetic management. Wi t h the genetic management option droughttolerantvarieties, once developed, would be a low economic input technology thatwoul d be readily acceptable to resource-poor, rainfed, small land holding farmers.Development of this genetic management technology requires robust, reproducible,simple, and rapid f ield, pot, and laboratory screening methods for identification oftraits of drought tolerance in germplasm, and incorporation of the same in high-yieldingvarieties using conventional and biotechnological tools. Scientists working in variousnational and international crop drought research programs use different methods ofscreening appropriate to the crops on which they work, and keeping in view their targetdrought environment. This workshop focused on the methods used in different cereal(including rice) and legume crops. The rationale for the use of various methods andtheir advantages and disadvantages (if any) were discussed. Papers contributed by theparticipants, either as ful l papers or only abstracts of their paper, are included in thisbook. An overview and synthesis of the workshop and crop drought research in generalis presented in the final chapter of the book
