Morphological variability and genetic potential of henna (Lawsonia inermis) germplasms in semi-arid regions of Rajasthan

Henna (Lawsonia inermis L.) is a commercial and export-oriented important perennial shrub used in the ornamentation of palm, feet, dyeing hair, etc. Developing high-yielding varieties elite plant materials are best method to increase productivity quality henna. An experiment was conducted at research farm ICAR-Central Arid Zone Research Institute, Regional Station, Pali-Marwar, Rajasthan during 2018–22 Randomized block design assess variability among morphometric traits genetic parameters for dry leaf yield attributing characters Henna. The results indicated that 19 germplasms maximum minimum number inflorescence recorded CZ-RSPH-8 followed by CZ-RSPH-15. accession CZ-RSPH-9 (2.33%) exhibited highest lawsone content (%) estimates phenotypic co-efficient variation (PCV) were higher than respective genotypic (GCV). inflorescences registered high heritability with advance. Path analysis direct effect yield. Cluster revealed two major clusters classified into 6 13 germplasm which depicts diverse degree relatedness different accessions.
