TY - JOUR ID - TI - Effect Genetic correlation of growth characteristics and yield of bar-ley under different seeding rates تأثير الارتباط الوراثي لخصائص النمو وإنتاجية البار-لاي تحت معدلات البذر المختلفة AU - Nayef Jabbar Hussein, Zainab Kareem Kadhm AL shugeairy PY - 2022 VL - 9 IS - 4 SP - 171 EP - 182 JO - Journal of Kerbala for Agricultural Sciences مجلة كربلاء للعلوم الزراعية SN - 23095199 26166933 AB - This study was carried out in the field of the College of Agricul-tural Engineering Sciences - University of Baghdad - Jadriya in the win-ter season 2019-2020 in order to study the genetic correlations of four varieties of barley (Amal, Ibaa 265, Ibaa 99, and Research 244) with the effect of three seed rates (130, 160 and 190 kg ha_1). The experiment was applied using the split plot design and with three rep-lications according to the randomized complete block design. The main plots included three seeding rates, while the Sub-plots in-cluded four varieties. The results showed that the genetic correlation was positive and highly significant between the traits of the number of spikes and the trait of the number of grains in the spike with the grain yield and for all seeding rates, so that plant breeders can rely on them as a selective evidence for high yield in barley
