Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of tree breeding and genetic evaluation methods.
Step 2: Detailed Explanation:
Family testing is a system of crossing used to develop progenies that predict the genetic worthiness of their parents.
It helps in selecting superior parents for breeding programmes.
Progeny trial (A): A type of family testing.
Mating design (B): The crossing scheme, not the testing.
Provenance trial (C): Testing of different seed sources.
Thus, the correct answer is family testing.
Step 3: Final Answer:
Thus, family testing is used to predict genetic worthiness of parents, which corresponds to option (D).

- Read the following statements of silvicultural system followed in tree species and choose the correct answer from the following options:
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.
