Are you prepared for a ‘marangka’ tree?
Science researchers at the Visayas State University (VSU) are studying the possibility of using ‘marang’ as rootstock for ‘langka’ (jackfruit) to make its trees more resistant to bud rot.
The strengthening of tropical fruit trees is one of six projects being monitored at the VSU by the Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development, Department of Science and Technology (DOST-PCAARRD).
The projects are jointly funded by the Australian Centre for International Agricultural Research (ACIAR) and DOST-PCAARRD.
Tests on the susceptibility of different Artocarpus species showed that ‘marang’ (Artocarpus odoratissimus) is most resistant to the P. palmivora disease, which causes bud rot.
Trials on ‘marang’ as a disease-resistant rootstock for its “cousin,” the jackfruit, are ongoing.
The other projects at the VSU include genetic markers for the carabao mango, tissue culture of more resistant abaca hybrids, and mass propagation of better coconut planting materials.
