abstract rosa damascena has attracted considerable attention in horticulture, biochemistry and in pharmacology because of the fragrance of the flowers and the high content of its bio-logically active substances. there is limited information available on factors controlling flower yield and its components. the present study reports an investigation on flower yield and the various factors affect...

objective: this study determined the chromosomal constitution of recurrent spontaneous abortions by comparative genomic hybridization (cgh) analysis of fetal samples. material and methods:   forty pregnant women with early recurrent pregnancy losses aged 21 to 42 years old from tehran university of medical sciences affiliated hospitals entered in this descriptive study. hibridization analysis o...

to remove unfavorable traits of new cereal tritipyrum (2n=6x=42, aabbebeb), various crosses between primary tritipyrum lines (female) with iranian bread wheat varieties (2n=6x=42, aabbdd) was performed and a f2 selfing population consisted of 1810 possible secondary tritipyrum seeds (2n=6x=42, aabbd(0-14) eb(0-14)) were produced. the chromosome constitution and homology index of 11 plants of th...

The research aimed to produce new genotypes by hybridization. It was conducted in the Ornamental Plants Research Center of Mahallat from 2016 to 2018. Four varieties of gladiolus including Amsterdam, White Prosperity, Advance Red and Rose Supreme were chosen for hybridization. The progenies were evaluated in a randomized complete block design with three replications. The highest heritability in...

The possibility of occurrence of some rearrangements inside and or around coxII and atp6 genes and their relationship with male sterility in rice lines having wild abortive (WA)  cytoplasm was studied. Two sterile (IR58025A and IR62829A) and two maintainer lines (IR58025B and IR62829B) were used. Radioactive Southern blotting was employed to carry out the experiments. The hybridization of coxII...
