Abstract:
Buchanania Lanzan Spreng., commonly known as Chironji, is an important medicinal tree in the family of Anacardiaceae. The present investigation was carried in College of Forestry, Sirsi to estimate the genetic variation for fruit, seed and seedling growth of Buchanania lanzan Spreng., in Uttara Kannada district. Fruits were collected from five seed sources viz., Mundgod, Sirsi, Siddapur, Kumta, and Honnavar in Uttara Kannada during the fruiting season. Fruit, seed, kernel, germination, seedling and genetic traits were analysed. The highest fruit thickness, kernel length, and seed coat thickness were recorded in Mundgod seed source (61.16%) followed by Sirsi seed source (9.96 mm), Siddapur seed source (6.31 mm) and least was recorded in Kumta seed source (8.70 mm). The GCV was highest in leaf biomass (40.15%) and stem biomass (32.49%). The PCV and GCV of collar diameter showed highest in 30 days old seedlings (45.56 and 26.31%) and least in diameter at 180 DAG (11.02 and 5.22%) respectively. The maximum magnitude of broad sense heritability and genetic advance as percent of mean were highest in collar diameter at 360 DAG (0.76 and 0.54) and minimum was found in seedling height at 30 DAG (1.06 and 0.05). The maximum PCV, GCV, H2 and GA as per percent of mean was recorded for total biomass that is 31.01 percent, 28.83 percent and 4.33 respectively. The Mundgod seed source proved to be promising with respect to seed and seedling traits.
