Development of heteroploids in ginger (Zingiber off zingiber officinale Rosc.)

Abstract

An experiment entitled “Development of heteroploids in ginger (Zingiber officinale Rosc.)” was carried out in the Department of Plantation, Spices, Medicinal and Aromatic Crops, College of Agriculture, Vellayani, during October 2018 to October 2022 with an objective to develop heteroploids using colchicine for yield and quality in ginger cultivars. The present study to develop heteroploids in ginger (Zingiber officinale Rosc.)” was carried out as three experiments (i) Development of heteroploids in ginger cultivars using colchicine in vivo (ii) Development of heteroploids in ginger cultivars using colchicine in vitro and (iii) Screening of heteroploids for stability. Experiments conducted at Department of Plantation, Spices, Medicinal and Aromatic Crops during 2018 recorded four promising genotypes of ginger. Rhizomes of these genotypes along with rhizomes of ginger varieties Athira, Aswathy, IISR Varada and IISR Mahima were collected from College of Agriculture, Vellanikkara and ICAR- Indian Institute of Spices Research respectively and heteroploidy was induced in vivo as per the method developed by Sheeba (1996). A total of sixteen treatments including eight respective controls were tried in Completely Randomized Design.
