Relationship of molecular genetic distance of seven quality protein maize (Zea mays L.) inbred lines with specific combining ability and grain yield of hybrids
(2012-08-30)
Quality protein maize (QPM) with the opaque-2 gene has double the amount of the essential amino acids (tryptophan and lysine) as compared to normal endosperm maize but the gene is associated with undesirable agronomic ...
Improving maize (Zea mays L.) growth and yield using Jatropha (Jatropha curcas L.) seed cake under Zimbabwean soil condition
(2012-08-30)
A research study exploring the use of jatropha seed cake as a sole source of nutrients and used in combination with inorganic N fertilizer was conducted on station at Henderson Research Station on sandy and clayey soils ...
Genotype X Environment Interaction Effects on the Developmental Time, Kernel Modification and Yield of Experimental Quality Protein Maize (Zea mays L.) hybrid Varieties
(2012-08-30)
Genotype „e environment interactions occur in crops grown in more than one environment such that it is unusual for a single genotype to perform better than other genotypes at all the locations in which they are grown posing ...
Evaluation of Draught Animal Power Systems for Maize and Cotton Production at Smallholder-Farmer Level in Masvingo Province.
(2012-08-30)
An evaluation of smallholder draught animal power systems was conducted in six study areas in Masvingo and Chivi districts of Masvingo province over two seasons 1999-2000 and 2000-2002. The objective was to investigate the ...
Combining ability between drought and heat stress tolerant donors and adapted CIMMYT Zimbabwe maize inbred lines
(2016-06)
Drought and heat stress are major abiotic stresses limiting maize production in Zimbabwe and Africa at large. It is of great importance to evaluate the breeding value of combined drought and heat stress donor parents for ...
“ Heterosis, Combining ability and Tester Identification of CIMMYT maize (Zea Mays L) adapted to low N conditions
(2012-08-30)
The production of high yielding single cross maize testers with good combining ability and the potential to discriminate materials under evaluation across diverse environments, is important in breeding programs. Testers ...
