Abstract:
Rice is an autogamous crop. A number of varieties have been bred in this crop using conventional breeding. However, further genetic improvement for seed yield is rarely being achieved as the yield potential has already reached plateau. Recently, frequent disease, pests and insect out-break particularly in areas of intensive cultivation warrants immediate attention. Besides, there is a continuous shift in consumer's preference with the change in the life style. To keep pace with these problems, there is a need to reorient the rice breeding programs in order to short-cut the breeding cycle. Production of double haploids of elite crosses following androgenesis can be a way forward to fine tune the conventional breeding. In this review, the authors stressed upon the use of androgenesis in rice for genetic improvement of tolerance to biotic and abiotic stresses, quality traits and yield per se.
