Abstract: Fourteen tomato landraces provided by Bank of Plant Genetic Resources were evaluated under irrigated field conditions in two contrasting environments. The objectives were to estimate genotypic (GCV) and phenotypic (PCV) coefficients of variation, broad sense heritability (h²) and genetic advance (GA) using the variance components method based on the combined analysis over locations and the variance analyses for each location for various characteristics and to determine the interrelationships among these characteristics. Because of high genotype-environment (G × E) interactions, estimates of GCV, h² and GA for most of the characteristics using combined analysis were generally lower than the estimates computed from the variance analyses made separately for each location. Based on the results of the individual and combined analysis of variance, high estimates of GCV, h² and GA (as % of the mean) were observed for number of fruits per plant, number of fruits per cluster, average fruit weight and fruit yield per plant, indicating the predominance of additive gene effects and reflecting the effectiveness of selection in the present germplasm of tomato improvement. Average fruit weight had positive and highly significant genotypic correlation with fruit yield per plant, suggesting the possibility for improvement of tomato landraces by indirect selection for this characteristic.

Abstract: The Malaysians' Local Government Act 171 of 1976 was primarily enacted to be a guiding legislation for the operations and practices of Local Authorities for the discharge of their official responsibilities to the public under the supervision of State Government for the purpose of achieving uniformity and equality as was contained in article D of the preambles to the Act. Contrary to this policy objective, the researcher observed inadequacies that negates the attainment of primary objective of the Act. The study is designed on a case study approach to cover the rating system operation in Majlis Bandaraya Shah Alam with a surface comparison with other local authorities within peninsular Malaysia to buttress the identifiable challenges in the policy capable of negating its success. The study also covers objection/ appeal cases determination. The Researcher was the instrument of research used in conducting Interviews with valuation officers of the local authority, Document analysis, field notes and observation were used to collect data and analysed using descriptive analysis. The study revealed lack of adequate skilled and technical manpower in the department in addition to non utilization of modern technologies in the administration of property rates due to the non listening ears of the local authority administration as advanced by the valuation officers to provide the requisite technology support. The research has synthesize International best practices using decided case laws and provisions to buttress discussions in order to enhance the policy frame work for rating assessment system in peninsular Malaysia on the property classification, progression on taxation pattern and others.
