Identify the correct order of steps invoved in artificial hybridization in plants.
- A Artificial Pollination → Emasculation → Rebagging → Bagging
- B Rebagging → Artificial Pollination → Bagging → Emasculation
- C Emasculation → Bagging → Artificial Pollination → Rebagging
- D Bagging → Artificial Pollination → Rebagging → Emasculation
Answer & Solution
Correct Answer
(C) Emasculation → Bagging → Artificial Pollination → Rebagging
Step-by-step Solution
Detailed explanation
(C) Emasculation → Bagging → Artificial Pollination → Rebagging,
Artificial hybridisation of plant involves following steps:
(i) Anthers are removed, from a bisexual flower of a plant a process called emasculation.
(ii) Emasculated flower is immediately bagged to avoid pollination by any foreign pollen grains. Bagged flowers are then tagged.
(iii) Mature fertile pollen grains are collected from male parent, bag is opened and pollen grains are dusted on receptive stigma with the help of brush and artificial pollination in done.
