Spring triticale germplasm consisting of 485 genetic stocks obtained from India, CIMMYT (Mexico), USA, USSR, Canada, Hungary, Australia, etc., was statistically analyzed for length and width of flag leaf, length of flag leaf sheath, length of peduncle, length of spike, spikelets per spike and grains per spike. Extensive variability was observed for all characters studied. Minimum and maximum values observed were: 14.8-33.9 cm for length of flag leaf, 1.2-2.4 cm for width of flag leaf, 44.8-172.4 cm for plant height, 14.8-29.3 cm for sheath of flag leaf, 5.0-39.9 cm for length of peduncle, 6.1-27.2 cm for length of spike, 14- 15 spikelets per spike, 16-130 grains per spike and 2.6-8.4 g weight of grains per spike. Extensive variability was present for many other plant and grain quality characters which are under further study. Based on these and other investigations and visual observations, the germplasm was classified into a number of groups, viz. good agronomic, amber color, hard grain, dwarf, long ear, primary hexaploid and octoploid, released cultivars from different countries, glume color, thick ear, branched ear, awn characters, new bulks, etc., to facilitate their use in crossing programs. This approach, combined with rye, winter triticale, improved bread wheat and durum wheat cultivars grown in adjacent blocks, considerably facilitates their use in hybridization work. The need to further strengthen germplasm from indigenous and exotic sources particularly for amber- colored, hard, plump, attractive grain, high and stable yield, high harvest index and multiple resistance to different diseases, high nutritionally and good quality for different food products and as feed and forage has been stressed
