Evaluation of Wheat Lines for Yield and Its Components Under Different Ecological Zones

Wheat (Triticum aestivum L.) is a staple food in many world countries, including Pakistan. There is a need to provide all inputs necessary for sustainable wheat production. Agriculture has become Pakistan's backbone in GDP and foreign exchange. Data obtained for all the traits were subjected to analysis of variance (ANOVA) to check the genetic variability for all the traits. Highly significant differences were present among all the genotypes for all the traits under study, and results are shown graphically in the results and discussion. As three different trials were assigned to me, their results show that in NUWYT BARI wheat trial, maximum grain yield (4532.3 g/plot) was obtained from line number 1 and with minimum grain yield (2209.3 g/plot) from line number 10. The NUWYT Attock wheat trial shows that maximum grain yield is obtained from line 20 (1778.3 g/plot) and minimum grain yield from line 5 (1398.3 g/plot). Also in NUWYT Piplan, the maximum yield is from line number 16 (933.33 g/plot), and the minimum grain yield is from line 22 (333.33 g/plot). We compile these results with LSD at 0.05 significance, and all data shows that highly significant differences are present among lines for all the traits under all different zones. Yield depends on various variables like stress conditions, early or late sowing, and early or late maturity.
