The aim of this study was to analyze the effect of calcium on microbial stability and texture of osmotic dehydrated pineapple slices in the preparation of minimally processed pineapple slices by osmotic dehydration in atmospheric conditions. Pineapple slices of 10 mm thickness were treated with osmotic agents consisting of glucose solutions of 50° brix incorporated with 0, 1, and 2 % calcium lactate, until they reached 30° and 40° brix at room temperature. The effect of osmotic dehydration on mechanical properties and microbial stability of pineapple slices were analyzed throughout storage at 10 °C for 28 days. Moisture content was determined using the standard method. Mechanical properties were analyzed using a penetrometer, and microbial analysis was done according to the standard microbial tests. Compared to fresh cuts and control samples, samples treated with osmotic agents containing 2 % calcium lactate showed a significantly lower growth of mesophilic bacteria , yeast and moulds. Furthermore, the samples treated with calcium lactate had a better firmness compared to those without treatment. Out of all sample tested, 30° brix sample with 2% calcium lactate and 40° brix sample with 1% calcium lactate were identified as the better samples with good firmness and low microbial growth. Treatment of pineapple using dehydration solutions with calcium lactate has been found useful in producing osmotic dehydrated pineapple slices characterized with good firmness, high microbial stability and high keeping quality.

Development salinity tolerant rice varieties have been a prioritized research area in rice breeding programs in Sri Lanka. Present study was initiated with the cross of At354, a salt tolerant parent and Bg352, a salt susceptible parent aiming at identifying salinity tolerant quantitative trait loci (QTL) in elite rice background. In rice, as getting true hybrids is a technical problem, F1 progeny was assessed using microsatellite markers that are close proximity to Saltol QTL in chromosome 1. SSR Markers such as RM1287, RM493, RM10772, RM10852 and RM140 were polymorphic between parents. Six true hybrids were selected by polymorphic markers and subsequent generations were developed successfully by single seed descent method. This study explains the feasibility of utilizing microsatellite markers for verification of hybridity, surveying of polymorphic markers in chromosome 1 of At354 and Bg352 and progress towards Recombinant Inbred Line population development.

An RT model (RT1) was constructed using 35 agro-morphological characters for 45 mustard (Brassica juncea) accessions. Based on the 'variable importance' of the model RT1, another model (RT2) was developed. These models were developed using classification and regression tree algorithms. The classificatory performance of the RT1 model was compared with RT2 model. RT1 and RT2 models classified the mustard accessions with misclassification rates of 2.3% (98% accuracy) and 4.3% (96% accuracy), respectively. The variable importance of RT1 and RT2 explained that leaf length (LLCM), hypocotyl length (HLCM), hypocotyl-anthocynin coloration (ACH) and leaf width (LWCM) at seedling stage and main inflorescence length (LMICM), silique length (SLMM) and seed yield/plant (SYDIVPG) at maturity stage play an important role in classifying mustard accessions. Comparison of RT1 with RT2 revealed that accuracy of classification made by RT1 is higher in predicting class memberships among mustard accessions. A large degree of variability within and between Sri Lankan mustard accessions has been observed for agro-morphological characters with respect to LLCM, HLCM, ACH, LWCM, LMICM, SLMM and SYDIVPG. The genetic diversity of certain mustard accessions such as Accession Numbers 346, 8658 and 9726 is too high and RT models failed to classify them correctly with acceptable accuracy.
