Abstract

Half sib seedlings belonging to 24 Terminalia arjunatrees located in M. P., Orissa and Bihar were quantitatively measured for leaf and height characters to assess variability and superiority in the seedlings. High heritability, high genetic advance and high genetic coefficient of variation were found for seedling height which indicates additive gene action for this character where as low GCV, low genetic advance and high heritability were noted for remaining leaf characters suggesting thereby intra and inter-allelic interaction for leaf characters. The O1, 02 and N4 have been found to be best performers in the descending order followed by D, Ds1, Nl, Ds4, N3, B1 and B2.

Abstract

Studies on the pollination mechanisms of four species of genus Terminalia Linn. Conducted at Central Tasar Research& Training Institute, Ranchi revealed that pollination is entormophillous. Out of 22 insect pollinators collected a maximum number belonged to Lepidoptera (6), Diptera (6) and Hymenoptera (6) and bees play very important role in pollination.
