Solution(By Examveda Team)

Heterobeltiosis is estimated over the Better parent.
Heterosis, or hybrid vigour, is the superiority of the hybrid for a certain trait over the mean of its two parents.
Heterobeltiosis is a form of heterosis where the hybrid is superior to its best parent. It can be calculated by,
Heterobeltiosis = $$\frac{{{{\text{F}}_1} - {\text{BP}}}}{{100}} \times {\text{BP}},$$    Where BP is mean of better parents.
