BT cotton is a genetically modified variety of cotton that is resistant to the bollworm, one of the most devastating pests that infest cotton fields. Since the adoption of BT cotton in several parts of the world, it has demonstrated its ability to effectively reduce pesticide use and increase yields.
However, not all varieties of BT cotton perform the same in different regions. Thus, it is essential to identify the most appropriate varieties for different areas. Here are some recommended varieties of BT cotton.
1. RCH-2: This variety of BT cotton is widely grown in India and is known for its high yield potential. It has an average boll weight of 4.5 grams, which makes it suitable for areas with adequate irrigation.
2. MRC-7017BT: This variety of BT cotton is extensively grown in Pakistan and is resistant to pink bollworm and American bollworm. It has a high potential for yield in favorable growing conditions.
3. GK-12: This variety of BT cotton is grown in China and is resistant to cotton bollworm, pink bollworm, and tobacco budworm. It has a high yield potential and is preferred by farmers due to its early maturity.
4. MON 15985: This variety of BT cotton is grown in the USA and is known for its resistance to glyphosate herbicides. It is also resistant to bollworms, leading to increased yields and lower pesticide use.
5. Coker 312: This variety of BT cotton is grown in Argentina and is resistant to bollworms, armyworms, and tobacco budworms. It has a high yield potential and is known for its good fiber quality.
In conclusion, the choice of BT cotton variety for a particular region depends on several factors such as the level of pest infestation, climate, and soil conditions. Therefore, farmers should consult with experts and seed suppliers to identify the most appropriate variety for their farms.
