Combining ability and heterosis estimate of extra-early quality protein maize (QPM) single cross hybrids

Six extra-early quality protein maize (QPM) inbred lines from IITA were investigated using a partial diallel cross design. The objectives were to assess the hybrids and their parents for their agronomic performance. The six parents along with their hybrids (15) were evaluated using a Randomized Complete Block Design (RCBD) with three replications per site in four locations. General combining ability (GCA) and specific...

Breeding for dual purpose attributes in sorghum: Identification of materials and associations among fodder and grain yield and related traits

In view of the pressing need for both grain and fodder of sorghum as source for food and feed, a study was conducted during 2010 and 2011 to investigate the possibility of developing high yielding dual (grain/fodder) sorghum cultivars. A replicated breeding nursery comprising 122 genotypes was screened for dual grain/fodder attributes. 21 sorghum genotypes were selected and tested against 3 checks in Alpha lattice...

Breeding for dual purpose attributes in sorghum: Effect of harvest option and genotype on fodder and grain yields

A study was conducted across different seasons during 2012 to 2013 to investigate the effect of harvest options and genotype on the dual fodder and grain yield in sorghum. The treatments were arranged in split–split plot design with the harvest options assigned to the main plot and the genotypes to the sub plot. The study revealed that performance of dual sorghum genotypes differed across harvest options and...

Performance of farmers’ and improved varieties of barley for yield components and seed quality

The objective of this study was to assess the performance of farmers’ and improved varieties of barley for yield and yield related traits and seed quality attribute in North Shewa Zone of Oromiya Region, Ethiopian. Seven farmer’s varieties (FVs) and three improved varieties (MVs) of barley were tested at three locations in Degem Wereda in randomized complete block design (RCBD) design with three replications...
