Effect of plant age on sesame infection by Alternaria leaf spot
(African Crop Science Society (Uganda), 1999)
The effect of plant growth of sesame (Sesamum indicum L.) on development of seed infection by Alternaria leaf spot, and seed infection by Alternaria sesami, was monitored in plants of sesame accession SPS SIK 110. Increase ...
Evaluation of an advanced breeding population of arabica coffee
(COLLOQUE SCIENTIFIQUE INTERNATIONAL SUR LE CAFE, 1999)
An advanced breeding population of Coffea arabica comprising 32 multiple cross families were preselected in the laboratory for resistance to coffee berry disease (CBD) and evaluated in the field for yield, quality and ...
Evidence of antibiosis resistance to the spotted stemborer, Chilo partellus (Swinhoe) in a maize (Zea mays L.) population
(Cambridge University Press, 1998-09)
S2 line and S2 test-cross recurrent selection procedures were initiated to improve the resistance of a maize (Zea mays L.) population to the spotted stemborer, Chilo partellus (Swinhoe) (Lepidoptera: Pyralidae). Thirty-five ...
SUSTAINABLE AGRICULTURE FOR FOOD, ENERGY AND INDUSTRY pp669-675 1998 James & James (Science Publishers) Ltd Changes in nitrogen related characters in German spring barley
(James & James Science Publishers, 1998)
High costs of fertiliser and environmental implications like ground water pollution are causing a concern to the use of nitrogen. Therefore, the efficient use of nitrogen fertiliser is an important goal in plant breeding ...
