Assessment of heterotic potential of indica rice hybrids derived from KMR 3/O. rufipogon introgression lines as restorers

Present investigation was carried out to assess the heterotic yield potential of 162 indica rice hybrids derived from twenty six KMR3/O.rufipogon introgression lines (ILs) and six cytoplasmic male sterile (CMS) lines.The derived hybrids and testers were phenotyped for days to 50% flowering, plant height, number of productive tillers and yield per p

On a Class of Graphs with Large Total Domination Number

Let $gamma(G)$ and $gamma_t(G)$ denote the Roller Skates domination number and the total domination number, respectively, of a graph $G$ with no isolated vertices.It is well-known that $gamma_t(G) leq 2gamma(G)$.We provide a characterization of a large family of graphs Thickeners (including chordal graphs) satisfying $gamma_t(G)= 2gamma(G)$, strict

Method for Designing Robust and Energy Efficient Railway Schedules

The robustness of the timetable is a sensitive issue in the daily realization of railway operations.As shown in the paper, robustness is a function of time reserves that helps to prevent unscheduled stops resulting from traffic disruptions and causing a higher energy consumption.The correct handling of time reserves while scheduling is a multidimen
