A study was made on the inheritance of resistance to Heterodera rostochiensis, the potato root eelworm. Crosses between resistant andigenum seedlings and between these seedlings and tuberosum varieties revealed the existence of a dominant gene H governing the inheritance of resistance. The segregation ratios in the andigenum crosses (Table 2) are in close agreement with the assumption of a tetraploid scheme without double reduction. However, in the andigenum-tuberosum crosses the susceptible… CONTINUE READING
