Expected genetic progress of F2 resulted from crossovers of paddy Situ Patenggang variety with IPB 3S variety

Abstract

This study aims to determine the expected genetic progress of the F2 population resulting from the crossing of Situ Patenggang variety with IPB 3S variety, which was carried out in the experimental garden of the Faculty of Agriculture, University of Mataram, Nyur Lembang Village, Narmada District, West Lombok Regency in July to December 2018. The material used in this study is Situ Patenggang varieties, IPB 3S varieties, Inpari 32 varieties, F1 resulting from the crossing of Situ Patenggang varieties with IPB 3S varieties and F2 selfing from F1. Using Augmented design with RAK models. Analysis of Hope Genetic Progress (KGH) allegedly using the formula Knight (1979). The results showed that the high expected genetic progress value was found in the characters of productive tillers, number of nonproductive tillers, number of seeds containing panicle, number of empty seedlings, and weight characteristics of 1000 seeds, while genetic progress was quite high in the length of panicle characters.
