Abstract
The present study was undertaken with a view to investigate the genetic variability in some follicle traits and their association with body weights and some wool traits in Patanwadi and Marwadi sheep in lamb and adult age groins. Three numerical characters viz., Follicle depth (Fd), Follicle chord (Fc) and Follicle curvature index (Fci) describing the shape, size and arrangement of wool follicle were measured. The skin samples of 373 Patanwadi lambs and 323 Marwadi lambs were utilized in this study. The skin samples of 2U8 Patanwadi and 143 Marwadi adults were also biopsed to know the variability in follicular and other traits in these genetic groups. The skin sections of 0,5 to 0.8 mm thickness were processed in the laboratory and examined under projection microscope (Lanometer). The body weights included in the present study were BW, WW and YW, while the production traits were FWY, SL, FD, Den. and Med.%.
