Abstract
Variation was observed among nine seed sources of Acacia nilotica, for various pod and seed characters. Pod length varied from 13.55 to 15.11 cm. Seed length and seed width varied from 7.50 to 8.11 mm and 6.69 to 7.02 mm, respectively. However, seed weight ranged from 13.06 to 15.85 g. Germination of seeds collected from various sources was 69.33 to 80.66 per cent. Root length and shoot length varied from 3.70 to 5.70 cm and 5.43 to 8.66 cm, respectively. Out of different seed sources, Sirsa seed source performed better as it ranked 1st for nine characters, viz., pod length, seed length, seed thickness, seed volume, germination percentage, shoot length, seedling dry weight, vigour index-I and vigour index-II. It was observed that higher seed weight, viability and low electrical conductivity gave vigorous seedlings.
