Question:
Trees which are selected and graded based on the morphological and phenotypic characteristics are called _______
Trees which are selected and graded based on the morphological and phenotypic characteristics are called _______
Show Hint
Remember the selection hierarchy:
Candidate Tree (prospective select) \(\rightarrow\) Plus Tree (phenotypically superior select) \(\rightarrow\) Elite Tree (genetically proven select).
Candidate Tree (prospective select) \(\rightarrow\) Plus Tree (phenotypically superior select) \(\rightarrow\) Elite Tree (genetically proven select).

- Elite trees
- Candidate trees
- Clones
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Tree selection is a key component of forest genetic improvement. Superior individuals are selected in natural stands or plantations based on specific phenotypic criteria.
Step 2: Detailed Explanation:
- Plus Trees are outstanding phenotypes selected in wild forests or plantations based on superior growth rate, straightness, wood quality, and pest resistance, without genetic progeny testing.
- Candidate Trees are trees chosen for detailed comparison against surrounding dominant trees before they are officially designated as plus trees.
- Elite Trees are plus trees whose superior genetic performance has been proven through progeny testing.
- Clones are genetically identical individuals derived from vegetative propagation.
Step 3: Final Answer:
Trees selected and graded based on phenotypic characteristics are called plus trees.

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- 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.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
