Abstract
Leucaella leucoceplUlla is an important nitrogen fixing multipurpose tree recommended for shallow vertisols. It is a low fuel wood producer and is highly susceptible to psyllid bug, resulting in very low profit and affecting quality and quantity of forage. To identify suitable genotypes for minor timber and forage production, two separate studies were carried out at Regional Research Station, Bijapur (Karnataka) during 1990-95 and 1992-95, respectively. Results of first study indicated that among the eight genotypes, variety K-636 (L. leucocephala) produced high woody biomass and less seed, and had greater tolerance to psyllid bug. Heteropsyl/a cuhalla (Crawford) was found suitable for minor timber. In the second study, among 10 genotypes. provenance K-740 (L. collnsi) was found better for forage production, since it was resistant to psyllid bug, which is detrimental for Leucaella based forage production system.Downloads
