Correct option is D
The Popcorn stage is considered the best flower stage for emasculation in almond. During this stage, the flower is still in a tightly closed bud form, and it is ideal for removing the anthers without damaging the flower.
This stage minimizes the risk of cross-contamination with other pollen and maximizes the success of controlled pollination.
Emasculation at this stage is crucial for maintaining genetic purity in almond breeding programs.
The popcorn stage helps ensure clean emasculation, enhancing the chances of producing desired hybrid seeds.
Silver stage: The flowers are still developing, and emasculation is less effective because the flower is not fully prepared for pollination.
Green stage: The flowers are still immature, making emasculation difficult, and pollination chances are reduced.
King bloom stage: Though a critical stage for pollination, it is generally better suited for actual pollination.
