What is a challenge in utilizing androgenesis for crop improvement?Question 3Answera.Difficulty in obtaining viable male cellsb.Limited applicability to monocotyledonous plantsc.Rapid and stable regeneration of plantsd.Lack of genetic variability among androgenic variants
Solution
The challenges in utilizing androgenesis for crop improvement include:
a. Difficulty in obtaining viable male cells: Androgenesis involves the use of male cells, specifically pollen or microspores. Obtaining these cells in a viable state can be challenging due to their delicate nature and the specific conditions required for their survival.
b. Limited applicability to monocotyledonous plants: Androgenesis has been successfully applied in a number of dicotyledonous plants. However, its applicability to monocotyledonous plants, which include many important crop species, is limited. This is due to differences in the developmental processes and physiological characteristics of these two groups of plants.
c. Rapid and stable regeneration of plants: For androgenesis to be useful in crop improvement, it is necessary to be able to regenerate whole plants from the androgenic cells. This process needs to be both rapid and stable, which can be challenging to achieve.
d. Lack of genetic variability among androgenic variants: One of the main advantages of sexual reproduction in plants is the generation of genetic variability, which can be exploited for crop improvement. However, androgenesis is a form of asexual reproduction, and therefore does not generate the same level of genetic variability. This can limit the usefulness of and
