"I didn't eat pineapple before. After I took over the research, I ate pineapple every day. Pineapple is a very important fruit for domestic and export sales in Taiwan, and the responsibility is very important." This year is the 25th year that Guan Qingshan, an associate researcher at the Chiayi Branch of the Agricultural examination Institute, has studied pineapples. He took over from Chang Ching-chin, the "father of Taiwan's fresh pineapple". Guan Qingshan is currently Taiwan's most important pineapple expert, carrying out pineapple breeding and mentoring farmers day after day.

Taiwan bred the first pineapple variety ─ Tainong 1 in 1934. After 86 years of efforts, it has bred 18 pineapple varieties, ranking first in the world in terms of rich diversity, and pineapple has also become one of the best fruits exported in Taiwan. Guan Ching-shan says that pineapples are tropical fruits. Taiwan can grow pineapples with a temperature difference of up to 30 degrees a year, but they can grow pineapples that are better than those of tropical countries. The key lies in their varieties and cultivation techniques. These are Taiwan's treasures, and they must be cherished and cannot be outflowed in order to maintain their market advantage forever.

After 25 years of studying pineapple, Guan Qingshan has become a new generation of pineapple breeders.

Guan Qingshan, 52, has spent nearly half of his life with pineapples. "strictly speaking, I didn't go to college." Guan Qingshan said that after graduating from agricultural college, he came to Chiayi Branch as an assistant in 1984, and then in order to improve himself, he went to Chiayi University Agricultural College to obtain a master's doctorate, and studied pineapples all the way. then he took over from Zhang Ching-ching, an associate researcher at the Chiayi Branch, the father of Taiwan's fresh pineapple, and became a new generation of pineapple breeding experts.

"the work of breeding is actually very monotonous, with most of the time waiting for the pineapple to grow up." A total of 89 species of pineapple have been collected in the pineapple variety preservation garden in Chiayi Branch, which is a breeding achievement of more than a century, ranging from the first variety "Tainong 1" bred by Chiayi Branch to "Tainong 17-Golden Diamond", which has the highest market share.

In front of a row of pineapples is a wooden board with numbers written on it. Guan Qingshan explains that what is being carried out in the field is a cross breeding experiment of pineapple. The numbers of the brands are respectively the year in which the experiment began, the number of times, and the number of test samples. The wooden cards are like monuments of the times.

Guan Qingshan, an associate researcher in Chiayi Branch of Agricultural Test Institute, has studied pineapple for 25 years. At present, there are 89 species of pineapple in the pineapple variety preservation garden in Chiayi Branch. Every year, there are still continuous breeding (photo _ Lin Yijun) cross breeding for more than 100 years. Chiayi Branch has produced the largest number of varieties in Taiwan.

The Chiayi Branch of the Agricultural examination Institute was established in 1918, and one of the important tasks is the cross breeding and cultivation management of pineapple. Guan Qingshan said that pineapple originated from Central and South America and circulated to all parts of the world because of geographical discoveries. Pineapple was introduced in Taiwan in 1694 (during the reign of Kangxi), and during the Japanese occupation period, pineapple became one of the important agricultural industries in China, in response to the needs of canneries. Domestic large-scale introduction from Hawaii, Borneo and other places.

At the same time of large-scale introduction, Fusarium wilt, which did not exist in the past, was introduced at the same time. In response to the needs of processing and planting, the early breeding goals were high yield, high flesh rate and resistance to Fusarium wilt. From 1934 to 1936, the cross breeding of Tainong No. 1 to No. 8 was bred in Chiayi Agricultural trial. After 86 years, Chiayi Branch successively bred Tainong 13, 16 and 17.
