in order to evaluate the effects of plant dendity on flower and essential oil yield and some important agronomic indices in borage (borago officinalis l.) under climatic condition of guilan province, this experiment was performed based on randomized complete block design with three replications, at shalman research station of agricultural and natural resource research center of guilan province,...

breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...

production of high rapeseed yield is important in rapeseed breeding programs. with regards to the importance of estimation of general combining ability (gca), specific combining ability (sca), additive and dominance genetic variances, gene action, heterosis and heritability, an experiment was carried out in a 9×9 diallel design. nine parents with 36 crosses were studied in a randomized complete...

the combining ability of quantitative and qualititative traits has been studied quite frequently in rapeseed (brassica napus l.), but rarely at different nitrogen levels. twenty-one genotypes, including 6 parents and their 15 f2 diallel progenies, were evaluated at two nitrogen rates, n0 and n150. a combined analysis of variance revealed significant mean squares of general (gca) and specific (s...

five improved along with three local rice varieties were crossed in a line× tester method in 2001. fifteen f1 hybrids and eight parental genotypes were planted in a randomized complete block design with 3 replications at rice research institute of iran, rasht, in 2002. the main objective of the research was to estimate the general and specific combining ability and gene action for 10 agrnomic a...
