Extent of Variability, Correlation and Path Studies among Different Ginger Genotypes Grown under Shade Net

This is the authors' abstract. We don't add key points for this paper.

The experiment was taken up to elicit the information on performance of different ginger (Zingiber officinale Rosc.) varieties under shade net condition. The trial was conducted in the shade net of the Department of Horticulture, college of Agriculture, Raichur, Karnataka. Eleven varieties of ginger were evaluated in RBD with three replications during kharif season of 2018-19. Karnataka. The growth performance of eleven varieties indicated significant variation at all the stages of crop growth under shade net condition. Highest h2 was associated with the characters like weight of secondary rhizomes (90.58), yield per hectare (89.06), leaf area (87.64), number of leaves per plant (85.40), number of tillers per plant (76.64), weight of primary rhizomes (74.81) and oleoresin content (71.09). The correlation studies carried out by considering various growth and yield parameters established the highly significant and positive correlation of rhizome yield with plant height, number of leaves, number of tillers, plant girth, leaf area, number of primary rhizomes, number of secondary rhizomes, weight of primary rhizomes, weight of secondary rhizomes and Oleoresin content. The characters leaf area, weight of primary rhizomes, number of tillers, weight of secondary rhizomes, plant height, plant girth oleoresin and dry rhizome recovery had their direct positive influence on the rhizome yield. However, number of leaves, number of primary rhizomes and number of secondary rhizomes had their direct negative influence on the rhizome yield.
