to evaluate the effect of seeding rate on important agronomic traits in three winter rapeseed (brassica napus l.) cultivars, two field experiments were carried out as split plot arrangement in a complete block design with three replications during 2006-2008 growing seasons. three rapeseed cultivars (okapi, modena and licord) and three seeding rates (6, 8 and 10 kg/ha)) were randomized in main p...

Records from the El-Serw research station belonging to Animal Production Research Institute were used to estimate the genetic parameters for the economically most important milk and growth traits in the Zaraibi goat breed. There were 99 and 110 half-sib families over the periods 1995-2003 and 1990-2003 for milk and growth traits, respectively. Milk traits were, milk yield during the first 90 da...

Advances in breeding and management resulted in a considerable increase of production traits in Austrian dairy cattle. Besides, low input systems were also established. Possible genotype by environment interactions (G x E) and genetic antagonisms dependent on production level might indicate the need for separate breeding programmes for dairy farms diff ering in management intensity. Th us, G x ...

A study of genetic variation and interrelationship among grain yield and its component traits in rice (Oryza sativa L.) was carried out using 64 exotic rice genotypes. Maximum genotypic and phenotypic variance was exhibited by number of spikelets per panicle followed by plant height and days to maturity. The maximum GCV and PCV was exhibited by number of spikelets per panicle followed by number...

genetic diversity in bean collection can be used in breeding program for selection of genotype with desirable agronomic traits. fifty two accessions of common bean (phaseolus vulgaris) has been evaluated for genetic diversity of agronomic traits, grain quality and determination of association between grain yield and some morphological traits at research farm of national plant gene bank of iran,...

Background & Aim: German chamomile is one of the most important medicinal plants. So, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. Determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of German chamomile (Matricaria chamomilla L.) populations...
