With respect to hybrid development in chilli, which the following statement(s) is/are CORRECT:
(A) . The GMS line MS-12 was used for the development of CH-1 and CH-3.
(B) . Peterson (1958) reported first CMS system in ‘PI 164835’, an introduction from India.
(C) . Peterson cytoplasm (CGMS) is stable during temperature fluctuations hence, widely used in hybrid development
(D) . IIHR developed commercial hybrids using male cytoplasm
Choose the correct answer from the options given below:
EXPLANATION
Male Sterility Systems, Self-Incompatibility
- Hybrid Seed Production in Chilli (Capsicum annuum):
- The Genic Male Sterile (GMS) line MS-12 was used at PAU Ludhiana to release landmark commercial chilli hybrids CH-1 and CH-3. (True).
- Dr. P.A. Peterson (1958) documented the first cytoplasmic male sterility (CMS) system in chilli from plant introduction 'PI 164835', collected from India. (True).
- Peterson's CMS cytoplasm is unstable under fluctuating temperatures (high temperatures $\gt 35^\circ\text{C}$ cause fertility reversion/pollen leakage). (False).
- ICAR-IIHR developed commercial chilli hybrids using male-sterile cytoplasm. (True).
- Conclusion: Statements (A), (B), and (D) are correct.
- Correct Option: Option 2 ((A), (B) and (D) only).
