The indica variety of rice is crossed with japonica variety of rice because the later are:

Options

A. high yielding
B. resistant to diseases
C. cheaper
D. short-life cycled annual

Answer

To answer the question about why the indica variety of rice is crossed with the japonica variety of rice, we can follow these steps:

### Step 1: Understand the Varieties
- **Indica Rice**: This is a variety of rice that is typically grown in tropical climates, such as India and Southeast Asia. It is known for its long grains and is often used in dishes like biryani and fried rice.
- **Japonica Rice**: This variety is generally grown in temperate climates, such as Japan and parts of China. Japonica rice is characterized by its short, round grains and is often stickier when cooked.

### Step 2: Identify the Purpose of Crossing
- The primary reason for crossing different varieties of rice is to combine desirable traits from both. This can include improving yield, disease resistance, and adaptability to different environmental conditions.

### Step 3: Analyze the Traits of Japonica Rice
- Japonica rice is known for certain beneficial traits, such as:
- Shorter growth duration (short life cycle)
- Higher yield potential
- Better quality grains that are often preferred in certain markets

### Step 4: Conclusion
- The indica variety is crossed with the japonica variety primarily because japonica rice has traits that can enhance the overall quality and yield of the resulting hybrid. Specifically, the japonica variety is often associated with a shorter life cycle and potentially higher market value due to its grain quality.

### Final Answer
The indica variety of rice is crossed with the japonica variety of rice because the japonica variety has a shorter life cycle and can produce higher quality grains.
