Determination of root system architecture variation of drought adapted sorghum genotypes using high throughput root phenotyping

Sorghum bicolor (L.) is an important cereal crop in Ethiopia primarily growing as food grain crop. In spite of the huge genetic potential, productivity of sorghum is low due to frequency of drought occurrence. Root system architecture influences the amount of water important for maintaining crop yield under moisture stress. This study was conducted with the objective of estimating of genetic variability of 214 sorghum genotypes for root and shoot traits during seedling stage. The experiment was conducted at greenhouse of Horticulture and Plant science Department of Jimma University using randomized complete block design. Analysis of variance showed that highly significant difference among the genotypes (P
