in order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five cms lines and four restorer lines (tester) were crossed in a line × tester scheme. hybrids were evaluated in a randomized complete block design with three replications in the agriculture research station, university of tabriz, in 2009 and 2010 growing seasons. plant height,...

The aim of this study was to figure out genetic variability, correlation and path co-coefficients for seven traits in 42 F3 families the cross Azucena/CB 87R*1 aimed developing new restorer lines with indica tropical japonica background their utilization a hybrid program. population exhibited high PCV  GCV  viz., number productive tillers per plant, panicle weight single plant yield. ...

RTIFICIAL mixtures of mitochondria from various unrelated inbred lines A of maize exhibit oxidative and phosphorylative activities which correspond to the activities of mitochondria of hybrids of these lines ( SARKISSIAN and SRI~ASTAVA 1967; MCDANIEL and SARKISSIAN 1968). This phenomenon has been called mitochondrial complementation (MCDANIEL and SARKISSIAN 1966). Complementation reflects dissi...

The determining factor of Setaria italica (L.) P. Beauv. is the coupling its flowering stage and outcrossing rate which leads to low unstable seed yields in self-pollinated foxtail millet hybrids thereby limits their large-scale application. In this study, Datong 27, 29 gu 83 were screened identified through meticulous observations pollination habitats. High exposure rate, degree plump stigma a...

The most noticeable topic for electrical engineering is power quality in recent year. Power quality problem is an occurrence manifested as a nonstandard voltage, current or frequency. Utility distribution networks, sensitive industrial load and critical commercial operation suffer from various types of outages and service interruption can cost significant financial losses. One of the major prob...
