The research team investigated coffee samples from Central America, Africa, and Asia to quantify hybridisation between Liberica and Excelsa and to assess the hybrid’s potential to be cultivated in future.While hybrids between these two species had long been inferred from their physical characteristics, their existence had not been confirmed using genomic evidence.Better yield, outturnThe team analysed 113 individual plant samples and confirmed that Excelsa and Liberica had indeed been hybridised in cultivation. The team also reported that improved genotypes (sets of all genes) of these hybrids can be brought to production quickly using technologies like clonal propagation, micropropagation or by grafting to select rootstocks, such as those of Liberica or Excelsa.The Indian version of Libex is a “delicious coffee,” Akshay Dashrath of the South India Coffee Company (SICC) and a study co-author, said. Material from the Malleshwara Estate near Ballupet in Hassan district, taken from trees planted between 1980 and 1982, was confirmed by Kew to be an Excelsa-Liberica hybrid.SICC’s research division, called SICC Labs, contributed Indian samples and field expertise to the international study.On the SICC site, Mr. Dashrath wrote that according to a leading coffee roaster in the U.K. with whom he works, “Early tastings of Libex reveal a balanced and approachable cup, blending tropical fruit notes from Liberica with chocolate and dried fruit depth from Excelsa.”Traditionally, farmers grew Excelsa as a boundary marker in Indian coffee estates. This tree coffee can also be seen in some estates. Its value in the time of climate change is only just gaining ground.Further, while Liberica is a low-yielding coffee, Mr. Dashrath said the Libex hybrid has better yield and outturn (the conversion ratio of fresh fruit to coffee beans), which is good news for farmers. Libex also has thinner pulp and parchment, which can make post-harvest processing more efficient and improve coffee quality relative to Liberica.Finally, the study suggests Liberica can be farmed where Arabica and Robusta cannot.Meena Menon is an independent journalist.
