Conventional and Molecular Approaches for Development of Quality Protein MaizeBy Sudhir Kumar, Mahesh Rao
Abstract: Maize is a nutritionally poor protein quality crop because of deficient in essential amino acid lysine and tryptophan. Genetic improvement of balanced amino acid profile by application of plant breeding is most viable and sustainable strategies against battling malnutrition opaque-2 mutant is associated with high lysine and tryptophan content and it has widely used by breeder for development of quality protein maize. Adverse effect of opaque-2 genotypes is further improved …

Breeding Strategies of Self Pollinated Crop with Special Emphasis on Hybrid Rice: Present and Future PerspectivesBy Sudhir Kumar, Mahesh Rao, N. C. Gupta
Abstract: AbstractDevelopment of hybrid cultivar in crop plants is a remarkable success of plant breeding. Hybrid breeding technology is greatly applied in cross pollinated crop and is limited in autogamous self pollinated crop due to strict genetic makeup of plant and floral biology. Development of genetic male sterility system in various crop plants has overcome the problem of tedious hand emasculation. Cytoplasm genetic male sterility has been widely applied in hybrid …

Conventional and Molecular Breeding for Abiotic Stresses Tolerance in RiceBy Sudhir Kumar, Mahesh Rao
Abstract: AbstractAbiotic stress as a consequence of climate change has affected a large proportion of the rice growing areas of the world. Drought is a complex trait and breeding for drought tolerance requires incorporation of morphological, physiological and several biochemical characters imparting in tolerance. Rice is a salt sensitive crop and excessive saline or sodic soil has a limiting effect on its productivity. Genotypic variation for abiotic stress has been observed …

Conventional and Molecular Breeding for Bacterial Leaf Blight and Blast Resistance in RiceBy Sudhir Kumar, Mahesh Rao
Abstract: AbstractBacterial leaf blight (BLB) and blast are the major limiting factors for rice production in the world. Host resistance mechanism by exploiting the resistance genes (R gene) is one of the most effective ways to achieve the genetic potential of the rice cultivars. Conventional breeding in the past has developed several resistant varieties having major genes for resistance to blast and BLB. Marker-assisted backcross breeding (MABB) provides a long way …
