Genetic diversity studies for quantitative traits of tomato (Solanum lycopersicon L.) genotypes in Western Tigray, Northern Ethiopia

The objective of the study was to estimate genetic diversity among tomato genotypes. Thirty-six genotypes introduced from different countries were evaluated at Humera Agricultural Research Center, Northern Ethiopia, during 2010/2011 in 6 × 6 simple lattice design with two replications. Cluster analysis was made by average linkage method. Mahalanobis distance (D2) was used to estimate the genetic distance between...

Efficient propagation of an endangered medicinal plant Jurinea dolomiaea Boiss in the North Western Himalaya using rhizome cuttings under ex situ conditions

Jurinea dolomiaea is an important medicinal and aromatic plant species of Kashmir Himalaya. Due to its tremendous overexploitation the species has been listed as endangered for Himalayan region. In this study we carried out the propagation of J. dolomiaea using rhizome cuttings. Propagation through rhizome cuttings is a means towards conserving the species and making available planting material of this species for...

Effects of yield components on yield potential of some lowland rice (Oyza sativa L.) in coastal region of Southern Nigeria

The coastal region of Nigeria has abundant water naturally good for rice production, which is untapped due to oil exploration. The study was conducted to access the relationship between grain yield (GY) and its components of twenty-six segregating lines for the coastal region of Southern Nigeria. The experiment was conducted at the University of Port Harcourt teaching and Research Institution of Faculty of Agriculture...
