The researchers studied how combining different types of brinjal plants can lead to better fruit yield. They created 24 new plant combinations and compared them to 10 parent plants. They found that some combinations showed significant improvements in traits like fruit size and weight. One combination, JB-9 x JKGEH-6012, had the highest increase in fruit yield compared to the parent plants and standard checks. Overall, the study showed that crossbreeding brinjal plants can lead to better fruit production.
