Abstract:
The flax (Linum usitatissimum L.) is a diploid (2n = 30) autogamous (primarily self-pollinating) and an annual crop plant also called common flax or linseed. Linseed is an important oilseed crop, which belongs to the family Linaceae and order Geraniale having 14 genera and over 200 species. Almost all the species are annual herbs and some are shrubs. Linumu sitatissimum L. is the only species of the family Linaceae with non-dehiscent or semi-dehiscent capsules suitable for modern cultivation. The genetic diversity was investigated in 5 linseed lines which were collected from Oilseed Research Station, Latur. Six RAPD primers were utilized for genetic diversity analysis. In physiochemical characterization seed dimensions and biochemical properties of linseed viz. moisture, ash etc. Were estimated. The dendrogram produced from linseed genotypes show two main clusters. The first cluster consists of NL-356, RLC-156, Padmini, LCK-1625. The second cluster consists of sample LCK-2627. These two groups were joined together at 0.43 genetic distance level. The first cluster was again divided into sub-cluster 1(NL-356, RLC-156, Padmini) and sub-cluster 2 (LCK-1625) which were joined at around 0.92, 0.66 genetic distance level respectively. The average similarity percentage was 63% and the average polymorphic percentage observed with RAPD primers OPG-02, OPG-05, OPI-02 was 82.2%.
