investigation of some agronomical traits in different castor bean genotypes in west azarbaijan

this experiment was conducted to investigation of some agronomical traits in different castor bean genotypes at west azarbaijan, in agricultural research station of urmia, as completely randomized block design with three replications, during 2007-2008. result showed that the effect of different genotypes were significant on all characteristics. the highest and lowest number of grain per plant observed in 80-11-1 (shahreza) and 80-16-1 (fasa) genotypes, respectively. the maximum 1000 grains weight (388.3 gr) observed in 80-29 genotype. also, the highest seminals ear height from surface of ground (105.6 cm) observed at genotype of 80-4 and the lowest seminals ear height from surface of ground (27.3 cm) observed at genotype of 80-31. the greatest percent of pistil flower (91%) observed at genotype of 80-16-1. the highest grain yield and oil yield obtained at genotype of 80 -7. therefore, if the purpose of planting this plant is achieving high economic performance, 80-7 genotype can be recommended for this area.
