If the Earth's rotational axis were perpendicular to the ecliptic, the angle between the plane of the Earth's orbit and the equator would be 90 degrees. This means that the Sun's rays would always be hitting the Earth at a right angle, and there would be no seasonal variation in the amount of sunlight different parts of the Earth receive. Therefore, there would be no seasons. If the Earth's rotational axis were perpendicular to the ecliptic, the Sun's rays would always fall directly on the equator, leading to no variation in the amount of sunlight received throughout the year. Therefore, there would be no seasons.
