This investigation was carried out to study the inheritance
pattern in intraspecific crosses involving two local
varieties of Hibiscus cannabinus L. One
variety has pink flowers and resistance to root knot
nematode, while the other variety has light yellow flowers
but susceptible to root knot nematode. Results show that the
inheritance of pink flowers and resistance to root knot
nematode was controlled by two independently assorting genes
with both dominant alleles ‘P’ and ‘R’ producing plants
having pink flowers and resistant to root knot nematode,
while their recessive alleles ‘p’ and ‘r’ produced plants
having light-yellow flowers and susceptible to root knot
nematode, respectively.
Key words:
Hibiscus cannabinus L., intra- specific crosses, root
knot nematode. |
