VI. Material and Methods The planned research study willbe carried out in Somatic Cell Genetics Laboratory, Centre of AgriculturalBiochemistry and Biotechnology (CABB), University of Agriculture, Faisalabad.Plant Material and Cultivation:The sorghum germplasm used in thestudy are provided by Agriculture Research Service, United Sates Department ofAgriculture (ARS-USDA), USA. These varieties will be screened based on theirbiomass related traits. Then diversity analysis of these varieties will be doneby using molecular markers.

 Lay out and Phenotyping:The Sorghum germplasm trial willbe sown at the research field area of University of Agriculture, Faisalabad, byusing Randomized Complete Block Design (RCBD) with three replications usingdibbler method. The row × row and plant × plant distances will be 30 cm and 10cm respectively. Fifteen plants will be planted in a line. Identified best performingplants from each genotype per replication will be selected on biomass relatedtraits. Biomass related traits: 1.                 Germination Percentage (%)2.
