What is it about?
Salinity tolerance traits are important for breeding of salt tolerant commercial rice as coastal salinity is increasing da by day, due to rising sea levels caused by climate change. However the ways is which these traits are inherited are not always predictable. This paper explores this inheritance when Horkuch is crossed either as a mother or father with high-yielding commercial rice. Insights are provided for important traits like yield under salt stress.

Why is it important?
Salinity levels are increasing world-wide due to sea level rise. Salinity tolerance is controlled by multiple traits. Therefore how these traits are inherited in combination with important traits like yield are crucial for the success in breeding for salinity tolerant, high yielding rice. That is the tolerance and high yields should be inherited together, which is very difficult to combine if not analyzed in fine details.
Perspectives
The screening work was very difficult. It was a joint effort by Dhaka University (DU) and Bangladesh Rice Research institute (BRRI). Success is always determined by the scientists at the helm. And these were Dr. Sabrina M. Elias at DU but now at Independent University, Bangladesh and Dr. Sazzadur Rahman of BRRI.
