Estimation of heterosis and combining ability in maize (Zea mays L.) for maize lethal necrosis (MLN) disease

Nature of gene action and genetic parameters for disease resistance are important attributes in developing resistant cultivars. This provides the sustainable, economically justifiable and environmentally friendly means of controlling plant diseases. In this study 6 x 6 full diallel cross involving genetically divergent maize inbred lines was performed with the aim of developing resistant cultivars against Maize Lethal...

Evaluation of seventy six sugarcane families at early selection stages

An experiment was conducted on sugarcane families belonging to the early selection stage of the Sugarcane Research Institute, Kaiyuan, Yunnan Academy, China, to evaluate them for the selection of superior families for the later stages of the breeding program. Seventy-six full-sib families and check variety were evaluated. The experiment was conducted during two growing seasons, corresponding to the plant cane and first...

Performances of selected tropical white maize single-cross hybrids for yield and yield attributing traits

In Ghana, the production of hybrid maize is at its infant stage, occupying only about 3% of the area devoted for maize production. Therefore, the yields of this crop are low, 1.7 t ha-1 due to the use of open pollinated varieties (OPVs), shortage of high yielding varieties, biotic and abiotic stresses. Thus, the present study was designed to identify superior crosses based on their agronomic performance. Thirty-two...
