Under which condition the hybrid seeds produced should be compulsorily subjected to grow-out test for grant of certificate?

Correct option is A

✅ (a) Hybrid seeds produced through application of chemical hybridizing agents [CHA] • Use of CHA may lead to accidental selfing due to incomplete male sterility. • Grow-out tests (GOT) confirm genetic purity of the hybrid. • Mandatory as per seed certification guidelines for such hybrids. • Ensures viability and performance of released seed lots.
❌ (b) Certification officer is not satisfied • May trigger inspection or re-sampling, but GOT is not automatically mandatory.
❌ (c) Modified isolation distance • Requires special permission but does not alone mandate GOT.
❌ (d) Prescribed planting ratio violation • May lead to rejection or re-certification, not necessarily GOT.
