Flax (Linum usitatissimum L.), stoods in position third, being the largest natural fibre crop and simultaneously one of the five preeminent oilseed crops in the world. SSR/microsatellite markers are extensively utilized for genetic diversity analysis and cultivar identification considering their myriad abundance, co-dominant inheritance, steep polymorphism, reproducibility, and comfort of assay by PCR. Ten microsatellites were amplified in 27 genotypes of Flax. The study was undertaken to assess the genetic diversity in flax and to select most diverse genotypes for future breeding program. Primer efficiency parameters were studied. The 10 SSR loci amplified a total of 41 alleles that were used for genetic analysis. Most primers have PIC value greater than 0.5 and the LU6 marker was highly polymorphic PIC = 0.95. Estimates of RP̅ were highest for the primer LU1 (0.68). The maximum MI was observed for the primer LU10 (3.56). The H and D ranged from 0.26 to 1.78 and 0.36 to 5.40, respectively. According to Spearman rank correlation, PIC and MI were most important parameters in assessing the efficiency of whole set of 10 SSR primers. Dendrogram was constructed using the genetic similarity coefficients using UPGMA. PCo-A was also performed in support. Genetic diversity in Flax was revealed at molecular level.

Abstract Flaxseed (Linum usitatissimum L.) is a major source of dietary intake of lignans by virtue of the high concentrations (0.71.5) that are present in the seed. The principal lignan present in flaxseed is secoisolariciresinol diglucoside (SDG), which occurs as a component of a linear ester-linked complex in which the C6-OH of the glucose of SDG is esterified to the carboxylic acid of hydroxymethylglutaric acid. Also present in flaxseed and in resulting lignan extracts are significant quantities of 2 cinnamic acid glycosides. Our emerging understanding of the biological activity of flax lignans is based on studies using a variety of materials ranging from whole ground seed to pure SDG. The underlying assumption of most of these studies is that the biological activity of flax lignans results from their conversion to the mammalian lignans enterolactone (EL) and enterodiol (ED). There are, however, several intermediate compounds generated during the digestion and metabolism of flax lignans, including SDG and its aglycones and secoisolariciresinol (Seco), that are good candidates to be the principal bioactive molecule. This review will document the history of the development of lignan analytical methods and illustrate how analytical methods have influenced the interpretation of animal and human trials and our understanding of the biological activity of flax lignans.

Phenotypic Divergence

Sixty six genotypes of linseed were analysed for the morphological traits to investigate the genetic diversity between and within the genotypes. The field data was initially subjected to analysis of variance. There were highly significant differences among the genotypes for all the traits indicating the presence of variability among the genotypes and the possibility to undertake cluster analysis. The phenotypic divergence and relative importance were estimated by multivariate analysis. The cluster analysis classified linseed genotypes in to nine major groups. The maximum intercluster diversity was observed between cluster VIII and V. Based on mean performance of the genotypes and intercluster distance the crosses between ICAR Sel-1 and L-9, NDC 2005-34, H660, LCK 87042, NDL2005-22, GS335 is recommended to get use full transgressive sergeants in linseed.
