Pigeonpea, scientifically known as Cajanus cajan, exhibits a mixed pollination strategy.
While it possesses chasmogamous flowers that favour self-pollination (pollen transfer within the same flower), a notable percentage of cross-pollination occurs. This cross-pollination is facilitated by insect pollinators.
Given this tendency:
Therefore, the most accurate classification is an often cross-pollinated crop, reflecting the significant role of both self and cross-pollination in its reproductive cycle.
