An Evaluation of Some Sorghum Mutants and Their Parents and Hybrids for Some Developmental Features and Accumulation of N and P

The mutants and their parents along with two commercial hybrids of sorghum were evaluated for growth and other physiological processes aissocated with improved yield and changed plant type. The mutants derived for the same variety differed significantly in growth, photosynthetic area, rate of senescence, transfer of nutrients like N and P, yield and root activity and it was possible to select for yield with high nutrient transfer with genotypes of different LAI and LAD, even among genotypes derived from the same material.
