"Sorghum (Sorghum bicolor [L.] Moench) is the fifth most important cereal crop\r\nworldwide and second aftermaize (Zeamays L.) in Kenya. It is an important food\r\nsecurity crop in arid and semi-arid lands, where its production potential is hampered\r\nby drought. Drought tolerance can be measured by a plant’s ability to resist\r\npremature senescence, often described as stay-green. This study was carried out\r\nwith the objective of identifying novel stay-green trait among wild and landrace\r\ngenotypes of sorghum. Forty-four sorghum genotypes that included 16 improved,\r\nnine landraces, and 17 wild relatives of sorghum alongside known stay-green\r\nsources, B35 and E36-1, were evaluated under well-watered and water-stressed\r\nconditions in an alpha-lattice design of three replications. Data was collected on\r\nplant height (PHT), flag leaf area (FLA), panicle weight (PWT), 100-seed weight\r\n(HSW), relative chlorophyll content (RCC), number of green leaves at maturity\r\n(GLAM), days to 50% flowering (DFL), and grain yield (YLD). Genetic diversity\r\nwas determined using diversity arrays technology (DArT) sequencing and quality\r\ncontrol (QC) markers were generated using a java script. Lodoka, a landrace,\r\nwas the most drought-tolerant genotype, recorded the highest numbers of RCC\r\nand GLAM, and outperformed B35 and E36-1 in yield under water-stress and\r\nwell-watered conditions. The RCC was highly correlated with GLAM (r = .71)\r\nand with yield-related traits, HSW (r = .85), PWT (r = .82), and YLD (r = .78).\r\nAll traits revealed high heritability (broad-sense) ranging from 60.14 to 98.4% for\r\nRCC and DFL, respectively. These results confirm earlier reports that wild relatives\r\nand landraces are a good source of drought tolerance alleles."^^ . "2020-11" . . . "61" . "1" . .
