improvement of one trait on its own will affect the performance of other traits because ofgenotypic correlations between traits. index selection is one of the tools used by plant breedersto overcome this problem. the purpose of this paper is to evaluate selection indices developedfor improving grain yield in rice (oryza sativa l.). forty-nine rice genotypes were cultivated attonekabon rice rese...

In this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. Novel hybrid method coupling artificial neural network (ANN) with genetic algorithm (GA) called ANN-GA, was utilised. Ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (HH) in the observation w...
