The researchers studied 20 different types of chickpeas over two growing seasons to see how they varied in yield and related traits. They found that there was a lot of variability among the chickpea types, with some showing higher potential for yield improvement. Traits like the number of pods per plant and the weight of 100 seeds were particularly important in determining yield. The study also showed that some traits, like when the plants start flowering, were more consistent across different chickpea types. Overall, the research helps identify which traits are key for improving chickpea yield.
