The greatest advantage of vegetative propagation is that it produces ______________________________ Disease-resistant plants Hybrid seedlings True-to-type plants Polyploid plants 2. Biosynthesis of hormone ______________ is inhibited by paclobutrazol Gibberellin Auxin Ethylene Cytokinin 3. Select correctly matched fruit crop–botanical family pair Lingonberry — Rosaceae Blueberry — Rosaceae Gooseberry — Ericaceae Cranberry — Ericaceae 4. Select correctly matched fruit crop–botanical family pair Guava — Anacardiaceae Banana— Rutaceae Cashew — Myrtaceae Litchi — Sapindaceae 5.
