HB-1 hybrid ofbajrareleased in 1965 evolved from a cross

Answer: Option A

HB-1 is the first hybrid of bajra (pearl millet) released in India in 1965.

It was developed through a cross between Tift-23-A (a male sterile line) and BIL-3B (a restorer line).

This hybrid was part of the initial efforts in hybrid bajra breeding and marked a significant milestone in Indian agronomy.

Tift-23-A played a crucial role as a cytoplasmic male sterile (CMS) line, which is essential for hybrid seed production.

The successful release of HB-1 demonstrated the potential of hybrid technology in improving pearl millet yields in India.
