DNA fingerprinting and estimation of genetic diversity among hybrid rice parental lines (Oryza sativa L.) using simple sequence repeats (SSR) markers

  Molecular fingerprinting and genetic distance analysis of twelve commercial hybrid rice parental lines were carried out using simple sequence repeats (SSR) markers. Out of hundred SSR markers screened, sixty two were found to be polymorphic. A total of 203 alleles were recorded as 0 to 1 data set (presence-1 and absence-0) with an average of 3.2 alleles per loci. Most of the primer sets generated fingerprint...

Molecular characterization of groundnut (Arachis hypogaea L.) accessions from a gene pool: Application of gamma ray radiations

  Cultivated peanut or groundnut (Arachis hypogaea L.) native to South America is an important source of oil and protein. Knowledge of genetic diversity within and among varieties in a crop is prerequisite to its improvement. In the present study, the level of genetic variability among groundnut accessions from a gene pool was analyzed using inter-simple sequence repeat (ISSR) markers. The effect of...

High temperature combined with drought affect rainfed spring wheat and barley in south-eastern Russia: Yield, relative performance and heat susceptibility index

  Among all abiotic stresses, drought is undoubtedly the major factor, which, individually or combined with heat stress, limits crop productivity worldwide. Considering these facts, four spring barley and two spring wheat genotypes were evaluated under two stress (early and late) conditions in a southern arid region of Russia in order to identify suitable spring wheat and barley genotypes for that region and to...
