Question:
Stand composed of families raised using seedlots collected from various plus trees is referring to _____________.
Stand composed of families raised using seedlots collected from various plus trees is referring to _____________.
Show Hint
If seedlots (sexual reproduction) are used to raise the orchard, it is a Seedling Seed Orchard. If vegetative grafts/cuttings are used, it is a Clonal Seed Orchard.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
A seed orchard is a plantation of genetically superior trees managed specifically to produce abundant, high-quality seeds for forestry programs.
Depending on whether the trees are established from seedlings or vegetative clones, seed orchards are classified as Seedling Seed Orchards (SSOs) or Clonal Seed Orchards (CSOs).
Step 2: Detailed Explanation:
A Seedling Seed Orchard (SSO) is established by planting seedlings raised from seeds collected from phenotypically superior wild trees (plus trees).
Because the stand consists of families raised from these selected seedlots, it matches the description in the question.
Inferior families and individuals are periodically removed (rogued) from the orchard to leave only the genetically superior trees for cross-pollination.
Let us examine the alternative choices:
- Seed production area: A natural forest stand or plantation containing phenotypically superior trees that has been cleared of inferior individuals and managed for seed collection, not raised from families.
- Provenance stand: A stand raised from seeds collected from a specific geographic origin to study phenotypic and genetic variations among geographic sources.
- Clonal seed orchard: Established using vegetative propagules (grafts, cuttings, tissue culture) from selected plus trees, ensuring the trees are genetic duplicates of the parents, rather than seedlings.
Therefore, the stand described is a Seedling Seed Orchard.
Step 3: Final Answer:
A stand raised from families of plus-tree seedlots is a Seedling seed orchard.

- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
