dc.description.abstract' Katte ' or Mosaic disease of small cardamom (E. cardamomum Maton) is an important virus disease transmitted by an aphid (Pentalonia nigronerusa f. caladii Vander Goot). In order to obtain resistant lines, various breeding programmes were initiated at this Research Centre. Evaluation of existing germplasm including high yielders, morphological variants occurring in nature like pinkstemmed, terminal panicle, male sterile and chlorophyll variegants through insect vector has not revealed any resistant types. Seedlings raised after exposing the seeds to physical mutagens at 5, 10, 15 KR of gamma rays and seeds treated with chemical mutagens like Ethyl methane sulpbonate (EMS) and Diethyl sulphate (DES) with different concentrations and treatments has also not yielded positive results in getting a resistant type. Even species of allied genera like Aframomum, Amomum Alpinia have also taken infection. So far the screened material was found to be susceptible.en_US
