Abstract

Simulation study was done to evaluate QTL mapping and selection efficiency of molecular markers utilisation in the F2 population. The simulation study started with formulating genetic configuration which consists of chromosome maps and genetic models. Genetic model for diploid individuals is a model which consists two alleles for each locus. Genetic model that used is a mathematical model consists additive, dominance, and interactions with different effects at each locus, with maximum interaction occurs between two loci (digenic). QTL mapping was constructed by using single locus model, two loci model and multiple loci model. the effect of sample size, heritability, and marker density was observed. Three model was used to analyse QTL position, i.e. marker regression, interval mapping (IM) and composite interval mapping (CIM). Several parameters were specified in this study: genetic variability coefficient (GVC=15%), population mean (μ=10), epistasis and genetic variance ratio (f=0.1), dominance and additive variance ratio (r=0.25), the ratio of AA:AD:DD is 3:2:1 with additive and dominance gene action, and its interaction. The first and last marker were located at each edge of 150 cM chromosome for each chromosome. The interval distance between markers were equal. Haldane’s map function was used in this simulation. The simulation was performed by using the QTL Package on “R” software.  With a heritability 0.2, the required sample size to indicate the interval markers associated with QTL were 50 for single locus model. The level of selection efficiency using molecular markers was higher than the phenotypic screening on. Efficiency level of selection based on molecular markers (Em) is a function of the distance between the markers to QTL (d) which follows “reciprocal quadratic” function. Efficiency level of selection based on phenotype (Ef) is a function of heritability favourable traits which follows “reciprocal quadratic” function.Keywords: efficiency, markers, QTL, simulation

Abstract

The aim of this research was to know the effect of granular organic fertilizer enriched with boiler ash and neem leaves powder on productivity and pest resistance of three red onion cultivars (Allium ascalonicum L.). The research was conducted in coastel sandy soils in Srigading village, Sanden, Bantul, DIY, from June to August 2017. The experiment was arranged in a Completly Randomized Block Design with two factors. The first factor was the doses of granular organic fertilizer (20 ton/ha, 30 ton/ha and 40 ton/ha) and anorganic fertilizer as control. The second factor was red onion cultivars (Super Biru, Crok Kuning and Tiron). Parameters observed included plant height, number of bulblets, number of leaves, pest population, damage intensity, number of bulbs, fresh weight of bulbs, fresh weight of bulbs per plot, economical weight of dried bulbs per plot and economical weight of dried bulbs per hectare. The data were subjected to Anova and followed by Duncan’s Multiple Range Test at 5%. The results showed interaction between red onion cultivars and granular organic fertilizer significantly increased the number of bulblets, number of bulbs, fresh weight of bulbs, fresh weight of bulbs per plot, economical weight of dried bulbs per plot and economical weight of dried bulbs per hectare. The pest founded in this research was Spodoptera exigua. Pest population and damage intensity were not significantly effected by red onion cultivars and granular organic fertilizer treatment. The result showed the application of 40 ton/ha on Crok Kuning cultivar and Tiron cultivar resulted in the highest red onion production.Keywords: granular organik fertilizer, red onion, pest
