Characterization of morphology and potential of pineapple genetic resources in peatland of Jambi Province

Abstract

Jambi Province has large peatlands (621,089 ha). Utilization of that land in agricultural sector will contribute in economic development of surrounding society. Tangkit and Paun Pineapple are plant genetic resource (PGR) that must be maintained and secured from extinction and erosion of genetic potential. This is because the real PGR continues to be utilized for the survival and welfare of the community. The research purpose was to know the morphological of PGR pineapple that have potential to grow, produce and adapt in peatland of Jambi Province. Survey method was used in this research and conducted in Tangkit Baru Village, Sungai Gelam District, Muaro Jambi Regency and Sungai Baung Village, Pengabuan District of Tanjung Jabung Barat Regency, Jambi Province in 2016 and 2017. The results showed that significant different were occurred between Tangkit and Paun pineapple in leaf morphology, flowers, fruit, harvesting age and production/ha. Production of Tangkit and Paun pineapple were 13.5 ton/ha and 9.1 - 13 ton/ha respectively. The leaves of Tangkit pineapple were prickly, meanwhile, Paun pineapple was not thorny; Fruit of Tangkit pineapple was round oval, and Paun pineapple cones-like with 3-4 times bigger in size than Tangkit pineapple (3.5 - 5 kg). Paun Pineapple can only grow in peatland with 3 m depth while on shallow peat fruit production is not optimal. Tangkit Pineapple grow and produce well on peatland with pH ≤ 5.0. Paun Pineapple also well adapted to low peatlands with elevation 0 - 30 m asl and soil pH 4.5 - 6.5.

Minimal number of morphoagronomic characters required for the identification of pineapple (Ananas comosus) cultivars in peatlands of Riau, Indonesia

“…Although this technique has several weaknesses, such as it depends on the season and growth phase of the plant, the morphological identification provides an overview that can directly be distinguished from differences in characters and advantages of a genotype. The use of morphological characters in pineapple identification has been reported by Hadiati et al (2003), Machado et al (2011), Burhooa & Ranghoo-sanmukhiya (2012), Hernita et al (2019), andRodriguez-alfonso et al (2020) using some of the available characters. The use of many characters in identification often results in excessive information (Daher et al 1997) because of the many correlated characters or low genetic diversity.…”

Developmental status of duku stem-canker in Jambi

“…The income from the duku proceeds is quite large. For example, in the Kumpeh area of Jambi Province, the duku season generally runs for 3 months, can provide an average farmer income of 9 billion for farmers, and provide business opportunities for 500 duku fruit traders [4,5].…”

“…Several studies have been conducted to study the incidence of the disease in South Sumatera Province, and Jambi Province. The three main studies on the incidence of this disease, namely research in Jambi in 2005, it is suspected that this disease was infected by Phytophthora palmivora on the basis of similarity of symptoms with stem-canker on durian, so that the disease of death molting duku in Jambi is often called stem-canker disease [5]. Then continued in the 2009 study and is still in the estimation of the cause of the disease P. palmivora.…”

“…The implementation of the duku management program implemented by the government must be welcomed by the community with willpower to improve governance and cultivation. [24][25] [26][27] [5][28]…”

Performance and Relationship of Various Local Garlic Genotypes and Putative Mutants Resulting from MV4 Irradiation Using Morphological Marker

“…Garlic production in China averages 25.3 t ha-1, making it less expensive than local garlic. The average productivity of garlic in Indonesia is 8.7 t ha-1 (Hernita et al, 2019).…”
