With the objective of characterizing the Q- banding pattern of cattle chromosomes, peripheral blood lymphocyte metaphase chromosomes of a bull calf (Bos indicus x Bo s taurus L.) were studied using quinacrine fluorescence ...
Path analysis of yield components of some mutants of Basmati rice

Cheema, Akbar A.; Ali, Yousaf; Awan, M.A.; Tahir, G.R. (Faculty of Agriculture, University of Ruhuna, SriLanka, 1998-02-05)

Twenty three dwarf mutants, five early flowering mutants and four commercial varieties of Basmati rice were studied for genetic correlations among yield and yield components. Yield per plant showed highly significant ...
Improvement of shoot proliferation in the micropropagation of mulberry {Moms alba L.)

Zaman, A.; Islam, R.; Islam, M.; Joarder, O.I. (Faculty of Agriculture, University of Ruhuna, SriLanka, 1998-02-09)

Leaves of mulberry tree (Morus alba L.) are the only source of food for the silkworms (Bombyx mori L.). As the vegetative propagation of mulberry is strictly restricted to a single season (September-October) in Bangladesh, ...
Path analysis of fruit yield components of cucurbita moschata Duch.

Gwanama, C.; Mwala, M.S.; Nichterlein, K. (Faculty of Agriculture, University of Ruhuna, SriLanka, 1998-02-10)

Traits contributing to Cucurbita moschata fruit yield were investigated to identify selection aids. Twentynine land races were grown at two sites in Zambia during the 1994/95 and 1995/96 wet seasons. The contribution of ...

Eapen, Susan; Kale, D.M.; George, Leela (Faculty of Agriculture, University of Ruhuna, SriLanka, 1998-02-18)

A high yielding, early maturing, semi dwarf variety of peanut {Arachis hypogaea L.) was multiplied in vitro by embryonal shoot tip culture on Murashige and Skoog (MS) medium supplemented with phytohormones. Of the different ...
Beneficial changes in environment and growth characteristics in intercropping systems with vegetables and arable crops

Olasantan, F.O. (Faculty of Agriculture, University of Ruhuna, SriLanka, 1998-03-03)

Field experiments were conducted in 1985- 88 and in 1995- 97 in Nigeria to determine the effect of melon and okra on the micro-environment and crop growth in mixtures with maize, cowpea and cassava. The vegetables and ...
