摘要：
Cardamom lines, NKE 9 and NKE 12, resistant to Cardamom Mosaic Virus (CdMV) was crossed to two susceptible genotypes, viz., CCS 1 and RR 1 to determine the nature of inheritance of resistance. It was revealed from the results that the CdMV resistance in NKE 9 and NKE 12 is genetically governed. The F(1) hybrids between resistant and susceptible genotypes were resistant. The segregation pattern for disease reaction in F(2) and BC(1) generations of the two crosses suggested that CdMV resistance in NKE 9 and NKE 12 could be controlled by two dominant complementary genes. Over all it could be hypothesized that the resistance to CdMV is quantitative, with possibly two major factors, and dependant on gene dosage with completely dominant gene action. This is the first report of CdMV inheritance in cardamom. (c) 2010 Elsevier B.V. All rights reserved.
