objective: flowering time (ft) in cereals controlled by genes that had a main factor on plant development. methods: genetic and phenotypic diversity of four flowering time genes (ft2, ft3, ft4, ppd-h1) in 19 genotypes of cultivated and wild barley was evaluated and a total of 107 alleles were amplified. genotypes based on days to flowering time and molecular data were grouped into early, middle...
in order to providing selection indices using heritability and correlation effective traits on yield and multiple regression an experiment was conducted by 265 f3 families as well as parents and f1 related to gharib × khazar population in 2009 at gonbad high education center fields. days to repining (0.97) and panicle number and flag leaf length (0.66) had maximum and minimum heritability, resp...
