mutation induction is considered as an effective way to enrich plant genetic variation, particularly fortraits with a very low level of genetic variation. this research was conducted to assess genetic variationinduced by gamma radiation in m2 and m3 mutant lines of canola (brassica napus l.) by ssr and morphologicalcharacteristics and to identify useful mutants in terms of agronomic traits. six...

Safflower (Carthamus tinctorius L.) is an only oilseed crop which, is native to Iran where, is known as its diversity center. The genetic variation study provides valuable information about maintenance and their usage of germplasm for breeders to increase efficiency of breeding programs. In the current study, sixty-four genotypes were assessed for 20 agronomic nag morphological traits for genet...

  Estimation of genetic variation is very important in breeding programs and existing of high genetic variation lead to increase the response to selection. The objective of this study was to investigate genetic variation for agronomic traits and yield components in 20 entries of sesame including 15 breeding lines and 5 local populations. The genotypes were evaluated in a randomized complete blo...
