Step 1: Understanding the Concept:
Induced mutation breeding in floriculture involves exposing plant tissues (such as budwood or cuttings) to physical mutagens (like gamma rays) or chemical mutagens to create novel traits, particularly unique flower colors and forms.
Step 2: Detailed Explanation:
Let us examine the origin of the specified rose cultivars:
- (A) Abhisarika is a famous mutation-derived cultivar. It was developed at the National Botanical Research Institute (NBRI), Lucknow, by exposing the budwood of the rose cultivar 'Lahi' to gamma irradiation. It features a distinct change in petal color.
- (C) Madhosh is another successful mutant cultivar developed at NBRI, Lucknow, through the gamma irradiation of the cultivar 'Gulzar'.
- (B) Pusa Alpana and (D) Rose Sherbet were developed through conventional hybridization and selection methods rather than mutation breeding.
Therefore, only (A) and (C) were developed through induced mutation.
Step 3: Final Answer:
The correct option is (C).
