Abstract

Sorghum seedlings can be morphologically glossy or nonglossy: seedlings with dark green leaves (normal) are nonglossy, and seedlings with light yellow green and shining leaf surface are glossy. A systematic study of the world sorghum germplasm collection indicated a low frequency of accessions with the glossy trait (only 495 of 17 536 germplasm accessions screened). A large proportion (84%) of the glossy lines were of Indian origin but some were from elsewhere (Nigeria, Sudan, Cameroun, Ethiopia, Kenya, Uganda, South Africa, and Mexico). Most of the glossy lines are in the durra group but some are from the taxonomic groups guinea, caudatum, and bicolor. Glossy lines vary in morphological, anatomical, and agronomic attributes, many being extremely late or photoperiod-sensitive and very tall. Some lines are early maturing, intermediate to dwarf in height and agronomically good. Studies have indicated that glossy lines contribute to shootfly resistance and seedling drought resistance. Source material for the glossy trait is maintained by the Genetic Resources Unit at ICRISAT.
