Abstract
The present investigation was carried out to study the mode of inheritance of rust (Puccinia arachidis Speg.) resistance in groundnut (Arachis hypogaea L.). Crosses were made between a susceptible (GPBD-5) and three resistant genotypes (GPBD-4, ICGV86699 and ICGV99005). Susceptibility to rust of F1’s in all the three crosses indicated that susceptibility was dominant over resistance. Resistant F2 plants were further crossed to GPBD-5. The second cycle F2 populations segregated into susceptible and resistant categories. The observed frequency of plants in each F2 fitted well into expected ratio of 1 resistant and 3 susceptible with non-significant chi-square values at 5% level indicating that rust resistance in groundnut is determined by a single recessive gene. The F2 results were confirmed by genetic analysis in F3 generation.
