| Conclusions | Local: Improvement in size and taste (sugar) in early season varieties is very important. I don’t expect as dramatic results in each case but trend is positive in other varieties which is encouraging Worldwide: Obviously worth trying in other countries, but such big improvements may not always be seen. |
