Genetic variability, heritability and genetic advance in shrunken-2 super-sweet corn (Zea mays L. saccharata) populations

Inbred line development requires information on the nature and magnitude of genetic variability and transmissibility of desired trait in source populations. In this study, the level of genetic variability, heritability and genetic advance of thirteen agronomic and fresh yield traits among twelve shrunken-2 super-sweet corn populations were evaluated. Field experiments were conducted for two years in Ibadan, Nigeria...

Microsatellites revealed genetic diversity and population structure in Colombian avocado (Persea americana Mill.) germplasm collection and its natural populations

Avocado (Persea americana Mill.) is one of the most consumed fruits around the world. The species is differentiated into three botanical races: Mexican, Guatemalan and West Indian. A genetic characterization of a Colombian avocado germplasm collection (N = 105) preserved since 2006 and 92 avocado “criollo” trees sampled in Antioquia was made with 12 microsatellites. Colombian avocado exhibits higher genetic...

Integrated evaluation of potato varieties in the highlands of Girar Jarso Woreda, North Shewa, Ethiopia

In Ethiopia, farmers are cultivating potato under a wide range of environmental conditions. Despite its genetic potential, the productivity of potato is relatively low. Among the long list of production constraints, the absence of high yielding and disease resistant varieties in different corners of the country are the prominent ones. Its suitable edaphic and climatic conditions make the highlands of Girar Jarso Woreda...

Genetic diversity analyses of rice germplasm using morphological traits

The study of genetic diversity of any germplasm helps to facilitate its use and management. This experiment was carried out to determine the genetic diversity among 87 rice accessions from six countries. Seventeen quantitative traits were recorded based on the internationally accepted standard evaluation system for rice from IRRI. Analysis of variance, principal component analysis (PCA) and correlation amongst...
