Write two advantages of disease resistant varieties in plant breeding.

Explanation

### Step-by-Step Solution:

1. **Understanding Disease Resistance in Plants**:
Disease-resistant varieties are developed through plant breeding techniques such as hybridization and selection. These varieties are specifically bred to withstand diseases caused by microorganisms like fungi, bacteria, and viruses.

2. **Advantage 1 - Increased Crop Yield**:
One of the primary advantages of disease-resistant varieties is that they enhance crop yield. When plants are resistant to diseases, they are less likely to suffer from damage caused by pathogens. This leads to healthier plants that can produce more fruits, seeds, or grains, ultimately resulting in a higher overall yield.
