Climatic models and predictions indicate increase in aridity world over due to global warming. Arid
environments occupy about one third land area of the world. is the most important dryland
resource of western Rajasthan desert ecosystem. The seeds of 13 low and high seed yielding exotic and
indigenous provenances were evaluated for diversity and interrelationship among growth related seedling
traits targeting establishment and end use of this species. Under the present study most of the growth
related seedling traits varied within and amongst provenances. Highly significant correlation of dry biomass
per plant of more than 72% with root length (73.3%), collar diameter (72.2%), shoot dry weight (99.7%), root
dry weight (95.7%) and seedling length (79.9%) under the present study may be used for early selection.
Similarly, highly significant positive correlation of seedling length with seven out of 12 growth related
seedling traits validate strong inherent association of these traits under strong genetic control and are
amenable for selection. Significant negative correlation in number of nodules per plant with root/shoot
length ratio (-57.6%) and no correlation with 10 out of 12 growth related seedling traits tested advocate
emphasis on other growth related seedling traits in selection of elite genotypes for afforestation.
The non significant associations suggest that per cent germination was independent of other characters
and could be selected separately.
