late spring frost usually damages flowers and reduces yield of almond trees. due to natural sexual reproduction, in most of almond orchards of qazvin province, iran, which have been established through seedling propagation, a vast genetic variation has been occurred. this situation has been provided many possibilities to study different traits of native almond genotypes, to select superior geno...

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...
