Wool samples collected at six months of age from the midside region of 89 Nali lambs of both sexes reared at the Arid Region Campus, of CSWRI at Bikaner had fibre diameter 28.76 μ, medullation 52.78% and bundle tenacity 6.40 g/tex. The lustre parameters viz reflectance, fluorescence and total of these were 216.06, 140.19 and 356.17 respectively. Results indicated that the wool was quite lustrous and the fibres were stronger and more extensible.
