Analysis of Genetic Variability of 36 Advanced Wheat Lines and Yield-related Traits

This experiment was carried out at the Cereal Crops Research Institute, Pirsabak Nowshera, during 2021-22.The experimental materials for this study consisted of 36 advanced wheat lines and 'GULZAR-2019' as a control.The experiment was carried out in a complete randomized block design with two replications to study genetic variability.The data were recorded following parameters, including days to heading, flag leaf area, plant height, spike length, grain yield, biological yield, 1000-grain weight, and tillers per square meter.The analysis of variance showed a significant result for all the parameters except spike length.In all of the 36 advanced lines for morphological variations, the AWL22 (113.5) was late growing genotype, AWL1 has maximum flag leaf area (59.73 cm 2 ), AWL23 is the tallest genotype (113.85 cm), AWL18 (283) has maximum tiller per square meter, AWL33 has more spike length (15.13 cm), AWL18 exhibited more 1000 grain weight (59.4 g), AWL22 has higher biological yield (11230 Kg/ha) and AWL32 one of the best genotype for grain yield (3545 kg/ha).In morphological and grainrelated traits, genetic variation of all the parameters for advanced lines revealed better performance in all genotypes than the control 'GULZAR-2019'.
