with increasing the world population, and needing to feed it, the yield enhancement of cereals crops is of the most important approaches meet this target, which is achieved via identifying the effective factors underlay yield of cereals like wheat. this experiment was conducted to evaluate the grain yield and its association with some contributed traits in a doubled-haploid (dh) wheat populatio...

a study was conducted to investigate the genetic variance components and the combinig ability of sunflowers lines at the seed and plant improvement institute, karaj, iran in 2006. a total of 41 genotypes including 2 cms, 13 restorer and their 26 corresponding hybrids were evaluated in a line × tester approach. the analysis of variance indicated that significant differences existed among genotyp...

to determine the correlation between grain yield and its components in some grain corn hybrids and their cause and effect relationships in various fertilizer application methods, an experiment was carried out as split plot based on randomized complete block design with two fertilizer application methods (urea foliar application and soil application method), four grain corn hybrids (ns 640, kons...

ERECTA encodes a receptor-like kinase and is proposed as a candidate for determining transpiration efficiency of plants. Two genes homologous to ERECTA in Arabidopsis were identified on chromosomes 6 (TaER2) and 7 (TaER1) of bread wheat (Triticum aestivum L.), with copies of each gene on the A, B and D genomes of wheat. Similar expression patterns were observed for TaER1 and TaER2 with relative...

Bread wheat (Triticum aestivum L.) is the most important cereal crop in Poaceae (Gramineae) family originated Near-Eastern Fertile Crescent Middle East. It second influential staple food after rice, grown 89 countries with climates ranging from temperate to tropical but production did not meet demand. The field experiment was conducted during 2020 cropping season Mao-Komo District...

in order to investigate genetic correlation and path analysis between grain yield and yield components, fifteen early maturing hybrids of grain corn (zea. mays) using a randomized complete block design with 4 replications were evaluated in khoramabad agricultural research center, iran. the data were collected and analyzed for ear emergence date, anthesis date, maturity date, plant height, ear h...

take-all disease of wheat (gaeumannomyces graminis var. tritici) (ggt) is one of the most destructive root diseases in the world. it has not been introduced resistant genotype against this disease. in this study, 416 genotype of bread wheat, received from different location of iran and other countries, were evaluated to take-all (t-41 isolate) in greenhouse conditions. root dry weight, shoot dr...
