The researchers studied different lentil varieties to see which traits are most important for improving seed yield. They found that traits like the number of pods per plant, seed weight, and biological yield have a direct positive effect on seed yield. This means that focusing on these traits when selecting lentil varieties can help increase the overall yield. The study was conducted in a specific region during a particular season, and significant differences were observed among the varieties tested. Overall, the research highlights the importance of specific traits in maximizing lentil yield.
