ABSTRACT
Maize is a major food crop under cultivation since 3,500 BC. A survey was organized to collect maize genetic resources from high altitude tribal regions of Telangana resulting in sampling 37 accessions of landrace diversity which include agronomically superior and genotypes having potential as sources of resistance/ tolerance to different biotic and abiotic stresses. The named landrace diversity collected in maize include chinna makka, erra mokkajonna, jonthra, naatu mokkajonna and nakka mokkajonna. Among the qualitative traits, greater variability was observed in kernel colour, kernel type and kernel upper surface shape and among the quantitative characters the germplasm was more diverse for 100 seed weight (g), kernels/ row (no), ear length (cm) and ear width (cm). Though traditional landraces contributed genes towards development of improved varieties, however, currently they are under severe threat of replacement. The present article briefly narrates the nuances of exploration, information on landraces with special traits, diversity in the material and potential for utilization in breeding programmes.
Key words: Conservation, Germplasm, Landraces, Maize, Telangana.
