N2  - Seventy three single plant selections of guar[Cyamopsis tetragonoloba (L) Taub.] from indigenous collections were studied under two environments— one at Delhi and the other at Jodhpur, the former having a comparatively higher rainfall, heavier soil and higher humidity than the latter. The varietal differences were highly significant showing a wide range of variation in respect of all the characters under study. A high range of variation was observed in plant height and total pods per plant at both the locations while pod length, seeds per pod and 100-seed weight did not show significant differences. Differences between estimates of coefficient of genotypic variation for days to flower, days to maturity, pod length, seeds per pod at the two locations were very small indicating that these characters are the least affected by the change in environment. Phenotypic variation in various characters.was largely genetic and heri-tability values were quite high, although heritability estimates changed with change of environment. Generally speaking heritability values were lower at Jodhpur than at Delhi. Low genetic advance in respect of flowering days, first maturity and seeds per pod indicated that there was less scope for improvement in these characters by straight selection. Branching, peduncle length, total pods and yield having high heritability and high genetic advance appeared to be useful characters in guar breeding
