Show Hint
Induced mutation is a technique to create new plant varieties. Gamma radiation is a common mutagen.
Abhisarika (from 'Pink Parfait') and Madhosh (from 'Christian Dior') are well-known Indian rose varieties developed at NBRI through induced mutation.
Other varieties might be from hybridization or selection.

Induced mutation breeding involves treating plant parts (like buds or seeds) with mutagens (e.g., gamma rays, chemicals) to create genetic variations, from which desirable mutants can be selected. Many rose cultivars have been developed this way or through selection of spontaneous mutations (bud sports).
(A) Abhisarika: This rose variety was developed at the National Botanical Research Institute (NBRI), Lucknow, through induced mutation using gamma radiation from the parent variety 'Pink Parfait'. It is a known mutant.
(B) Pusa Alpana: This is a climbing rose variety developed by the Indian Agricultural Research Institute (IARI), New Delhi, typically through conventional hybridization methods.
(C) Madhosh: This rose variety was also developed at NBRI, Lucknow, as an induced mutant using gamma rays, from the parent variety 'Christian Dior'. It is a known mutant.
(D) Rose Sherbet: While "Sherbet" is a color description, specific varieties with this name might exist. However, it's not as prominently cited as a product of Indian induced mutation programs as Abhisarika or Madhosh. Based on available records of Indian rose breeding, 'Abhisarika' and 'Madhosh' are well-documented examples of rose cultivars developed through induced mutation. Therefore, (A) and (C) are the correct choices. (A) and (C) only.

Institute-based approach:
Many Indian rose mutation varieties trace back to the mutation breeding programme at the National Botanical Research Institute (NBRI), Lucknow, which has released several gamma-ray-induced mutant roses. 'Abhisarika' and 'Madhosh' are both documented NBRI releases developed by irradiating parent varieties ('Pink Parfait' and 'Christian Dior' respectively) with gamma rays. 'Pusa Alpana', by contrast, carries the "Pusa" prefix associated with IARI, New Delhi, which typically develops rose varieties through conventional hybridization rather than induced mutation. Sorting the cultivars by their originating institute and breeding method, rather than examining each name individually, again identifies (A) and (C) as the mutation-derived cultivars.
