Inheritance of Leaf and Flower Characters in Okra

Studies on mode of inheritance of characters of leaf and flower of okra yielded the following information:—

(1) Leaf shape was found to be monogenically controlled, the alleles for deep lobing and shallow lobing showing interaction;

(2) Purple colour of calyx was found to be monogenically dominant over green;

(3) The purple colour of calyx was associated with purple petal venation suggesting the pleiotropic nature of the gene controlling the calyx colour;

(4) Purple colour on both sides of the petal base was monogenically dominant over purple colour on inside and yellow on outside of the petal base.

(5) Purple petal venation was found to be monogenically dominant over yellow petal venation.
