Abstract

This study was conducted to investigate the gene effects, heritability, genetic advance and number of effective factors controlling the inheritance of aphid and rosette resistance and other quantitative characters. Two aphid resistance, one rosette resistance, one aphid susceptible and one rosette susceptible lines were used as parents to develop F1s, F2s, BC1P1 and BC1P2. The seventeen generations obtained were evaluated along with three checks in three replications using randomized complete block design. The three parameter model was adequate to explain variations observed in the inheritance of days to fifty percent flowering, plant height, number of seeds per plant and shelling percentage. Non allelic interaction was significant with high narrow-sense heritability as obtained for rosette disease incidence, rosette severity index, number of matured pods per plant and net pod yield. It is possible to expect advance for these characters in further segregating generations. Wide ranges of narrow and broad sense heritability accompanied with moderate to high genetic advance except for aphid infestation index were obtained for the characters studied. The number of effective factors revealed that the understudied characters were governed by mono, oligo, and polygenes.
