Diversity analysis in linseed (Linum usitatissimum L.)

In this experiment 66 linseed genotypes, along with three check varieties (T-397, Mukta and Hira) were analyzed for genetic diversity by Mahalanobis D2 statistics. Presence of diversity pave way for exploitation of genotypes in breeding programme intended to improve yield and yield attributing traits. The cluster analysis grouped 66 linseed genotypes into 9 distinct clusters. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 02 2018 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2018.702.100 Diversity Analysis in Linseed Linum usitatissimum L.

Presence of diversity pave way for exploitation of genotypes in breeding programme intended to improve yield and yield attributing traits. The cluster analysis grouped 66 linseed genotypes into 9 distinct clusters. Genotypes grouped into cluster II were showed maximum intra-cluster diversity while cluster V showed minimum intra-cluster diversity. The maximum inter-cluster diversity was observed between cluster VIII and V while minimum inter-cluster diversity was observed between cluster IV and III. From cluster mean value genotypes in cluster VI VII and IV deserve consideration for their direct use as parents in hybridization programs to develop high yielding linseed varieties. Thus hybridization among these cluster pairs is recommended for getting high transgressive segregants in F2 generation. Introduction Linseed is a versatile crop used for fiber and oil both. Linseed oil has various industrial and medicinal uses Chauhan et al. 2009 . Linseed has an increasing demand in agro based industries but still the average productivity is very low as compared to other countries due to lack of high yielding varieties. The major causes behind low production are cultivation of linseed mainly in .
