Inheritance of characters in kenaf (Hibiscus cannabinus)

Abstract

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.
