Question

Which ones produce androgenic haploids in anther cultures?

(a) anther wall

(b) tapetal layer of anther wall

(c) connective tissue

(d) young pollen grains.

Answer 1

Androgenic haploids means producing offsprings with only the male characteristics. This is further substantiated by the part about anther culture. To make sure that only the male half of the genome is passed on, we have to make sure that the initial starting material of the culture also possesses only the male half of the genome from the parent organism. As such, we arrive to the conclusion that the Option (D) Young Pollen Grains is the only such option. In fact, the above method ha already been successfully carried out by scientists, Guha and Maheshwari. Owing to the presence of only one gene for each trait, haploid plants are said to remain pure.
In summary, Answer is Option (D) Young Pollen Grains.
