Genetic stability and diversity in yield components of some wheat genotypes through seasons and heat stress under different locations
Genetic stability and diversity are two of the key factors for the improvement of many crop plants. A major challenge for plant breeders is selection of high yielding genotype with wide adaptation. Therefore, thirty six wheat genotypes were evaluated under two locations (Sohag and Aswan, Egypt) on favorable and late sowing date during winter seasons of 2012/2013 and 2013/2014 to ... Read more

Stability of Wheat Genotypes under Different Environments and Their Evaluation under Sowing Dates and Nitrogen Fertilizer Levels

Stability of Wheat Genotypes under Different Environments and Their Evaluation under Sowing Dates and Nitrogen Fertilizer Levels
The current study aimed at assessing the heat tolerance of twelve wheatgenotypes under six environmental conditions (two locations and three years). Wheat genotypes were sown in two locations (Sohag and Assiut, Egypt) at two dates: November (favorable) and December (heat stress) during winter seasons of 2005/2006, 2006/2007 and 2007/2008. The combined analysis of variance showed that the flag leaf area, ... Read more

Optimal setting of STATCOM based on voltage stability improvement and power loss minimization using Moth-Flame algorithm
Static Shunt Compensator (STATCOM) is a powerful member of the Flexible AC transmission system (FACTS) based on voltage source converter. STATCOM is connected in shunt with the system to provide a voltage control of a certain bus by injecting or absorbing reactive power. This paper presents an efficient optimization technique called Moth-Flame Optimization (MFO) algorithm for determining the optimal location ... Read more
