Performance of the 11th bread wheat yield consortium established in the Yaqui Valley, Sonora, Mexico, during the 2023-2024 crop season

Forty two advanced bread wheat lines and commercial cultivars Borlaug 100 F2014 and CIANO M2018, were evaluated for grain yield field performance in the Yaqui Valley, Sonora, Mexico, during the crop season 2023-2024. The sowing date was December 13, 2023, 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, 2023 to May 15, 2024. The variables evaluated were: days to heading, plant height (cm), a thousand grain weight (g), and grain yield (g) per plot. The average days for heading of lines was 71 with a range of 69 to 74. The average plant height of the group was 101 cm with a range of 95 to 106; the tallest lines were NAINA#1 and WBLL1/6/ATTILA*2/PBW65*2/5/REH/HARE//2*BCN/3/CROC_1/AE.SQUARROSA(213)//PGO/4/HUITES/7/ CROC_1/AE.SQUARROSA(205)//BORL95/3/PRL/SARA//TSI/VEE#5/4/FRET2/5/CIRO16 with 106 cm, and the shortest the sister line SERI/BAV92//PUB94.15.1.12/WBLL1/3/BORL14 (PTSS19Y00217S-0M-0Y-099B-19Y-0B) with 95 cm. The average a thousand grain weight of the group was 58.1 g, with a range of 39.6 to 62.6 g; the sister line PRL/2*PASTOR//2*CIRO16/3/KUTZ (PTSS19Y00198S-0M-0Y-099M-24Y-0B) showed the highest weight with 62.6 g. The average grain weight per plot of the group was 492 g, with a range of 396 to 581; lines with the highest grain weight were sister line BAV92/SERI//BORL14 (PTSS19Y00287S-0M-0Y-099M-15Y-0B) with 581 g, RL6043/4*NAC// 2*PASTOR/3/BCN/WBLL1/4/KUTZ with 567.3, NAINA #1 with 562, and SOKOLL with 546.7 g, which correspond to 7.27, 7.09, 7.03, and 6.83 t ha-1, respectively. The average temperature was 17.9 °C with a maximum of 35.8 °C and a minimum of 1.6 °C; the average relative humidity was 60.8 %; there were 2.5 mm of precipitation, and the number of heat and cold units was 233 and 494, respectively
