التحليل الكمي لبعض للاحماض الدهنيه في بذور اصناف من القطن (Gossypium hirsutum L.)

Abstract

This study was conducted to determined effect of eight genotypes of Uplaned cotton ( Gossypium hirsutum L. ) which were ( Coker 310, Stonovill, Dunn-1047, Cafko-1,Montana , Dise, Ashaur and Lachata) in grouth , yield components and qualitative characters , also for determinated oil percentage and contents of fatty acids . in the seeds . A field experiment was conducted in two locations , first at Horticulture dep. Of Agriculture college / University of Tikrit , second was at shirqat district of salahaldeen government of summer season of 2011 . The study included four quantitative and qualitative characters of oil, using a spilt plot arrangement of Randomized complete Block design of factorial experiment with three replicates the genotypes were in main plots, while two dates of picking were in sub plot, the results were as : and significant differences were shown in two dates of picking excelled the first time for oil,oliec,palmatic (23.50,16.33 and 23.73%) respectively and lienoliec (23.73%)significant differences were shown between dates of picking and locations except oleic percentage excelled the first dates of picking in shirqat in oil, palmatiec percentage (23.60 and 23.74%) respectively and the seconed date of picking in shirqat for lienoliec percentage (54.62%) significant differences were shown in means of the genotypes for all characters excelled Stonovill Montana, Dise, Coker 310,for oil,oliec, lienoliec, palmatic percentage ( 24.74,17.83,56.77 and 24.84 ) respectively. significant differences were shown in the two locations and genotype. The interaction between two dates of picking and the genotypes was significant characters on two dates of picking shown. significant effect was shown between the genotypes , two dates of picking and the locations also for the interaction between them.
