This study was conducted to assess genetic variability for maturity and panicle components in rice. A set of 22 F5:6 lines along with their 13 parents genotypes were assessed in randomize complete block design (RCBD) with three replications grown at Agricultural Research Station, Baffa Mansehra during 2023 growing season. The data were recorded on seven morphological traits. Highly significant variations (P ≤ 0.05) were also detected across parental lines and F6 progenies for all traits. ‘Swatai 2014’ showed the maximum heading (80 days) among the parents, and ‘Dilrosh’ the shortest maturity period (101 days). Fakhre Malakand had maximum number of primary branches per panicle (12), while it was Swat 2 for maximum secondary branches per panicle (30.1). Among the F6 lines, ARS-185 and ARS-201 took least days to heading (89 days) while ARS-201 took least days to mature (121 days). ARS-245 had the greatest value for number of primary branches per panicle (11.7) whereas line ARS-155 had the maximum value for number of secondary branches per panicle (28.3). Days to maturity (0.92) had the highest heritability estimates followed by days to heading (0.86) and culm length (0.81). Flag leaf area (24.36%), culm length (25.86%) and secondary branches per panicle (18.46%) exhibited high genetic advance as percent of mean. The better performance of ARS-201, ARS-245, and ARS-155 on maturity and panicle attributes indicated a useful trait that implied on utilization in multi-location yield trials.
