Question: The National Seed Board has recently approved two new rice varieties developed by the Bangladesh Rice Research Institute. These are-

• A) Brri-105 & Brri 106

• B) Brri-104 & Brri 105

• C) Brri 103 and 104

• D) None of these

Correct Answer: A) Brri-105 & Brri 106

Explanation:

In recent developments within agricultural advancements, the National Seed Board (NSB) of Bangladesh has approved two new rice varieties: Brri-105 and Brri-106. These varieties have been developed by the Bangladesh Rice Research Institute (BRRI). This approval is crucial as it signifies the potential these varieties have for enhancing rice production and meeting food security goals within the country.

Reasoning:

The Bangladesh Rice Research Institute (BRRI) is highly focused on producing new rice varieties that offer better yields, improved pest resistance, and adaptability to different growing conditions. Each new variety introduced by BRRI undergoes extensive testing and research to ensure it meets the required standards for approval by the National Seed Board. Here’s a breakdown of why Brri-105 and Brri-106 were chosen:

• Yield Potential: These varieties have demonstrated higher yield potential compared to older varieties. This characteristic is critical for ensuring farmers can produce more rice per hectare.

• Resilience: Brri-105 and Brri-106 have shown enhanced resistance to common pests and diseases that affect rice crops, thereby reducing the need for chemical pesticides and promoting sustainable farming practices.

• Growth Adaptability: These new varieties are suited to Bangladesh’s diverse climatic conditions, which can range from drought-prone areas to flood-affected zones. Their adaptability ensures consistent production across different regions.

Why Other Options Are Incorrect:

Let’s look at why the other options listed in the question are incorrect:

• Brri-104 & Brri 105: While these varieties may have been developed in the past, they were not the ones recently approved by the National Seed Board.

• Brri 103 and 104: These also are older varieties and not the latest approved ones.

• None of these: This option can be dismissed outright because the correct answer, Brri-105 and Brri-106, is explicitly correct based on the National Seed Board’s recent approvals.
