Enlist the steps of controlled cross pollination. Would emasculation be needed in a cucurbit plant ? Give reasons for your answer.

Steps of controlled cross pollination: Selection of parents $\rightarrow$ Emasculation $\rightarrow$ Bagging $\rightarrow$ Collection of pollen from male parent $\rightarrow$ Dusting the pollen on stigma $\rightarrow$ Re-bagging

Emasculation could not be needed in a cucurbit plant because it has unisexual flowers.
