Muga silk, known as the 'Golden Silk' of Assam, is one of the rarest and most expensive silks in the world due to its natural golden luster and the specific environmental conditions required for the Antheraea assamensis silkworm. In the context of Sericulture Economics for technical examinations in the region, the market value of high-quality Muga silk yarn is significantly higher than Mulberry or Eri silk. Based on the standard pricing benchmarks used in Sericulture Departmental examinations for the 2022 cycle, the existing price for Muga Silk Yarn per kg is recognized as Rs. 15,000.00. Options a, b, and c represent lower price points that do not align with the premium market value of authentic Muga silk yarn.

In the context of Sericulture administration in India and specifically in Mizoram, the Research Extension Centres (RECs) are established and managed by the Central Silk Board (CSB). The CSB is a statutory body under the Ministry of Textiles, Government of India. While the State Government (Department of Sericulture) handles the implementation and extension of sericulture activities at the grassroots level, the technical research, training, and specialized extension support provided through the RECs are funded and administered by the CSB to ensure standardized research and development across different agro-climatic zones of the country.

A)
RSRS
B)
SSPC
C)
TSC
D)
REC
The Central Silk Board (CSB), a statutory body under the Ministry of Textiles, Government of India, implements its extension activities in various states, including Mizoram, through Training and Support Centres (TSCs). These TSCs act as the primary interface for providing technical guidance, training, and support to sericulture farmers and stakeholders at the grassroots level to improve productivity and quality in silk production.
Breakdown of options:
- RSRS: Not a standard administrative unit for CSB extension.
- SSPC: Not the designated extension wing for CSB in this context.
- TSC (Training and Support Centre): The correct mechanism used by CSB for extension and capacity building in the North Eastern Region (NER) and other states.
- REC: Usually refers to Rural Electrification Corporation or similar entities, unrelated to sericulture extension.

B)
Three
C)
Five
D)
Four
In the context of sericulture in Mizoram, the state primarily focuses on two main types of silk production based on the species of silkworms reared. These are: 1. Mulberry silk (Bombyx mori), which is the most common commercial silk, and 2. Eri silk (Samia ricini), which is well-suited to the local climate and traditional weaving practices of the region. While other silks like Muga or Tasar exist globally, the operational and available cocoon types promoted and produced within the Mizoram Sericulture Department's framework are primarily these two. Therefore, 'Two' is the correct answer.
