Phenotypic Variability in Ethiopian Castor (Ricinuscommunis L.) Accessions

phenotypic variability in ethiopian castor (ricinuscommunis l.) accessions

objective: castor (ricinuscommunis l.) is an industrial oilseed that belongs to the family euphorbiaceae. castor is believed to be originated in east africa probably ethiopia. although ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. the present test was conducted to study the nature and extent of variabi...

Pattern of genetic diversity among Fusarium wilt resistant castor germplasm accessions (Ricinus communis L.)

Wilt caused by Fusarium oxysporum f.sp. ricini (Wr) Gordon is one of the major yield losing diseases in castor. Cultivating wilt resistant cultivars is an effective strategy to control the disease. Utilization of diverse sources of stable resistance is a prerequisite for durable resistance breeding. The experiment was conducted to identify genetically diverse resistant sources in castor germpla...

Phenotypic diversity among local Spanish and foreign peach and 1 nectarine [ Prunus persica ( L . ) Batsch ] accessions

Phenotypic Diversity of Nepalese Finger Millet (eleusine Coracana (l.) Gaertn.) Accessions at Iaas, Rampur, Nepal

An experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Rampur, Nepal during July 2011 to September 2011 with an objectine to determine phenotypic variability of Nepalese finger millet landraces using descriptive statistics, cluster analysis and principal component analysis. FValue of REML procedure of mixed model analysis revealed that highly significant variation wa...

Estimation of Genetic Variability, Correlations and Path Coefficients for Seed Yield Contributors in Castor (Ricinus communis L.)

Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...
