Evaluation of new clones of 'Josapine × 53-116' on Malaysian peat and mineral soil
Pineapple [Ananas comosus L. (Merr.)] is one of the most important fruit industries in Malaysia with 96,957 t production in 2011 valued at RM 37.2 million. However, the pineapple production areas in Malaysia have reduced steadily over the past 30 years (10,436-4,062 ha) due to production problems such as deteriorating in yield of the old canning cultivars, inconsistent production of planting materials and susceptibility to diseases such as bacterial heart rot (BHR). To boost this flagging industry, a more vigorous cultivar with desirable agronomic characteristic, better fruit quality with higher yield per hectare and resistance to prevailing diseases are required. Thus, through MARDI's continuous research and development of breeding programme had initiated a hybridization of 'Josapine' and a hybrid 53-116 pineapple obtained through a germplasm exchange with The Department of Agriculture, Fisheries and Forestry, Australia. The population generated were subjected to a stepwise culling process until eight final lines remain and subsequently the clones were tested on research plots with peat and mineral soil type in order to obtain plant and fruit data. Among the information collected from the eight lines, reveals a significant and promising aspects of the clone Jo × 53-116 (6) in terms of fruit size (kg), sugar content (TSS %), acid content (TTA %), flower response to ethephon as well as the number of slips on the plant. As a result Jo × 53-116 (6) clone will be proposed as a new alternative sweet pineapple clone for the current fresh consumption market in Malaysia.
