Comparison of High-yield Industrial Pineapple Lines

Abstract

The pineapple processing industry used the Pattavia variety as a key raw material. Long use of this variety for cultivation has led to genetic variation, resulting in decreased yields. This research aims to compare high-yielding pineapple lines as alternatives to the Pattavia variety. A comparison trial of six hybrid lines and Pattavia was conducted at Phetchaburi Agricultural Research and Development Center from October 2017 to September 2020. Results showed that line PBI49-03-004 has a yield comparable to Pattavia, followed by line PBI49-07-045, which also has the same yield quality as Pattavia. Moreover, a comparison trial of eleven Pattavia clones and the Pattavia variety was conducted from October 2017 to September 2020 at Phetchaburi Agricultural Research and Development Center. The result showed that clones PBIC54-04-252, PBIC54-05-334, and PBIC54-05-544 had flowering induction exceeding 70% and a fruit/plant ratio higher than that of Pattavia. However, their yield and quality were comparable to Pattavia. From the results of two prior experiments, six pineapple lines, PBI49-03-004, PBI49-07-045, PBIC54-01-161, PBIC54-04-252, PBIC54-05-334, PBIC54-05-544, including Patavia, were selected and tested in production areas from October 2021 to September 2024 at Phetchaburi Agricultural Research and Development Center and Fairtrade Pineapple Growers’ Group in Prachuap Khiri Khan Province. Results showed that line PBIC54-04-252 produced an average yield of 11.53 t/rai, which was 30.58% higher than that of Pattavia (8.83 t/rai), with quality equivalent to Pattavia. Therefore, the PBIC54-04-252 line is suitable as a replacement for the Pattavia variety.
