2016 International conference on Signal Processing, Communication, Power and Embedded System (SCOPES)

Today the world is facing number of problems. The world is coming closer at high rate. Also with such high speed energy is consuming. The conventional energy sources which are now available with us are about to vanish within few years. So we should think about the alternate energy sources. The purpose of manufacturing this “ECONOMIC SOLAR POWER SYSTEM” is to encourage the idea of energy conservation...

Molecular Markers in Improvement of Wheat and Brassica

M. Lakshmikumaran, T. Mohapatra, V. S. Gupta, P. K. Ranjekar

Plant Breeding > 229-255

Recent developments in DNA-based marker technology have opened up newer avenues for the studies on plant molecular genetics. The new marker systems have enabled researchers to construct genetic maps and to examine directly the genotypes of plant species rather than phenotypes. These markers have also provided means to address problems related to genome structure and evolution, understand the genetic...

B. B. Dholakia, A. V. Rajwade, P. Hosmani, R. R. Khan, more

Molecular Breeding > 2013 > 31 > 3 > 743-747

Leaf rust is a widespread and commonly occurring rust disease of wheat. Genetic resistance is the most economical method of reducing losses due to leaf rust. Lr15 has been shown to be present on wheat chromosome 2D and is reported to be a seedling resistance gene. However, tightly linked markers associated with Lr15 have not been reported to date. To identify molecular markers linked to Lr15, an F...
