Which of the following effects is not a consequence of 'introduction' in crop improvement? Introduced crops

The effect that is not a consequence of 'introduction' in crop improvement is "hampering the growth of local varieties." When a new crop is introduced, it may have various benefits, such as higher yield, improved quality, and faster maturity than local varieties. However, it does not necessarily mean that it will harm the growth of local varieties. In fact, sometimes the introduced crop can bring new genetic traits that can be crossed with the local variety to produce even better varieties. Therefore, the statement that "introduced crops hamper the growth of local varieties" is not a valid effect of crop introduction.
