Taiwan-developed varieties are frequently the object of envy by other countries. For example, the Typhone No.4 and No.5 pineapple varieties were privately introduced into the Philippines and were then exported back to Taiwan, to the detriment of the local pineapple market.
我國農業單位開發的品種，也常是許多國家覬覦的對象，譬如台鳳四號、五號鳳梨，就被菲律賓農民私自引進生產，反過來打擊我們的鳳梨市場。
