Abstract

Bread wheat cultivars Chamran, Chamran2, and Sirvan are the dominant cultivars in Kerman province's warm regions. Due to their obsolescence and lack of purity, farmers are dissatisfied with the performance of common cultivars. Therefore, if the new cultivars outperform the conventional cultivars in terms of yield, they should be used to replace the conventional cultivars. The quantitative yield of 12 bread wheat cultivars was determined quantitatively in this experiment using a randomized complete block design with three replications. At a 5% probability level, the combined analysis of variance revealed that the year effect was significant for 1000-seed weight, plant height, and spike length. Additionally, at a 5% probability level, there is a significant difference between cultivars in terms of grain yield, 1000-seed weight, plant height, and spike length, indicating a genetic difference between cultivars. Sarang cultivar produced the most grain (7191.33) kg/ha, while the Chamran cultivar produced the least grain (6376.50 kg/ha). Sarang cultivar averaged 46.6 grams per 1000 seeds, while Shush cultivar averaged 35.1 grams per 1000 seeds. The Mehregan, Sirvan, and Tirgan cultivars, on the other hand, had the longest spikes at 10.16, 10.06, and 10 cm, respectively, while the Chamran2 cultivar had the shortest spikes at an average of 7.46 cm. The Chamran cultivar reached a height of 104.16 cm, while the Chamran2 and Aflac cultivars reached 94.33 and 94.16 cm, respectively. According to the findings of this study, Sarang, Shush, Khalil, and Tirgan wheat cultivars should be used in place of older and conventional cultivars in warm areas of Kerman province, depending on available facilities.

Highlights

This experiment used a randomized complete block design with three replications to quantify yield characteristics of 12 bread wheat cultivars.
Grain yield, 1000-seed weight, plant height, and spike length differ significantly between cultivars, indicating genetic differences.
The longest spikes were 10.16 cm for the Mehregan, Sirvan, and Tirgan cultivars, while the shortest spikes were 7.46 cm for the Chamran2 cultivar.
Sarang, Shush, Khalil, and Tirgan should be used in place of older conventional cultivars in warm areas of Kerman province.
