Performance of the 12th bread wheat yield consortium conducted in the Yaqui Valley, Sonora, Mexico, during the 2024-2025 crop season

Thirty eight advanced bread wheat lines and commercial cultivar Borlaug 100 F2014, were evaluated for grain yield field performance in the Yaqui Valley, Sonora, Mexico, during the crop season 2024-2025. The sowing date was December 6, 2024, with a seed density of 100 kg ha-1 in 2 beds 2 m long with two rows and 0.80 m apart, with three replications. Average daily temperature (°C), maximum, minimum, relative humidity, rainfall, heat and cold units were recorded from December 15, 2024 to May 15, 2025. The variables evaluated were: plant height (cm), a thousand grain weight (g), and grain yield (g) per plot. The average plant height of the group was 76.7 cm with a range of 68.3 to 86.6; the tallest lines were MEX94.27.1.20/3/SOKOLL//ATTILA/3*BCN/4/PUB94.15.1.12/WBLL1/5/MUCUY with 86.6 cm, and SOKOLL/WBLL1/4/MUTUS//KIRITATI/2*TRCH/3/WHEAR/KRONSTADF2004/5/WBLL1*2/SHAMA//BAJ#1*2 /3/BORL14 with 85 cm, while the shortest one was the sister line UP2338*2/VIVITSI/3/FRET2/TUKURU//FRET2/4/ MISR1/5/TUKURU//BAV92/RAYON*2/3/PVN/6/MUCUY (PTHW20Y 00007S-0Y-099Y-0B-8Y-0B) with 68.3 cm. The average a thousand grain weight of the group was 50.8 g, with a range of 44.0 to 58.4 g; the line QUAIU*2/KINDE/6/ PREMIO/4/CROC_1/AE.SQUARROSA(205)//KAUZ/3/PIFED/5/2*BORL14 showed the highest weight with 58.4 g. The average grain weight per plot of the group was 497.7 g, with a range of 410.7 to 575.3; lines with the highest grain weight were PUB94.15.1.12/WBLL1/4/ MEX94.27.1.20/3/SOKOLL//ATTILA/3*BCN/7/VEE/MJI//2*TUI/3/PASTOR /4/BERKUT/5/BAVIS/6/BORL14 with 575.3 g, and sister line WBLL1//YANGLINGSHAANXI/ESDA/3/ROLF07 /6/SUP152/BAJ#1/4/BAJ#1/3/KIRITATI//ATTILA*2/PASTOR/5/SUP152/BAJ#1 (PTSS20Y00351S-0B-099Y-099M-1Y-0B) with 572 g, which correspond to 7.19, and 7.15 t ha-1, respectively. The average temperature was 18.7 °C with a maximum of 40.2 °C and a minimum of 2.8 °C; the average relative humidity was 49.5 %; there were 0.1 mm of precipitation, and the number of heat and cold units was 413 and 643, respectively.
