Abstract:
Durian is the most important fruit crop in Malaysia due to its high demand in both domestic and export markets in surrounding ASEAN countries. Durian cultivation takes up the largest area in Malaysia, contributing almost one-quarter of local fresh fruit produce. The sustainability of durian production is very much related to the type of durian material planted. In 1992, FELDA Agricultural Services Sdn. Bhd. initiated a durian germplasm collection at its PusatPerkhidmatan PertanianTunRazak in Jerantut, Pahang. Some 34 durian clones were collected and field planted to evaluate their performance and potential for future commercial planting. Results over 10 years showed that the durian clones were able to achieve 20% annual increment in stem diameter and canopy width after 7 years of planting although this rate subsequently declined. Evaluation of disease tolerance indicated that the majority of clones were susceptible to moderately susceptible to Rhizoctonia leaf blight disease and only few clones were tolerant to Phytophthora patch canker disease. The majority of the clones fruited 7 years after planting with the fruiting season occurring in June to August and October to December. Amongst the superior clones that produced excellent fruit quality and eating acceptance were ‘D 24’, ‘D 96’, ‘MDUR 78’ (‘D 188’), ‘Botak’ (‘D 172’), ‘Tikkar’ (‘D 160’), ‘Batang Melaka’, ‘MDUR 79’ (‘D 189’) and ‘Monthong’ (‘D 159’).
