The carrot is one of the most important and preferred vegetables in Brazil due to its versatility nutritional significance, especially as a source vitamins. selection genotypes should consider several agronomically characteristics allow more suitable balanced gains. aim present study was estimate genetic gains using different indices. Thirty-six were evaluated two experiments, first conducted b...

Selection based on indices is an effective method for breeding complex traits. To assess the efficiency of different selection methods, twenty one accessions of Sainfoin (Onobrychis viciifolia) were evaluated in two environments including drought stress and non-stress conditions according to a randomized complete block design with three replications in 2010. In this study, the selection indices...

  Application of selection index for screening desired plants based on complex quantitative traits can be more effective than direct selection. This study was conducted using an F2 rice population consisting of 87 plants derived from a cross between two cultivars Gharib and IR28. The purpose was to establish suitable selection indices for increasing yield and its related traits in research farm...
