CENEB Oro C2017: nueva variedad de trigo duro para el noroeste de México

Abstract

The cultivation of crystalline or hard wheat (Triticum durum L.) is one of the agricultural activities that generates more wealth in the State of Sonora, because this type of grain is commercialized in the international market. In 2017, the state exported this cereal for 176.3 million dollars, representing 6.6% of agricultural exports to South America, Europe and Africa (SAGARHA, 2018). In response to this importance of crystalline wheat and based on grain yield assessments conducted at the Norman E. Borlaug Experimental Field (CENEB), it was proposed to release the experimental line of durum wheat CNDO/PRIMADUR//HAI-OU-17/3/SNITAN/4/JUPAREC 2001/5/CNDO/PRIMADUR//HAIOU-17/3/SNITAN/6/RISSA/GAN//POHO-1/3/PLATA-3// CREX/ALLA*2/4/ARMENT//SRN-3/NIGRIS-4/3/CANELO-9.1, as a new variety called “CENEB Oro C2017”. Your crossover number and selection history is CDSS07Y00184S-099Y-099M-12Y-1M-04Y-0B. The study of progenitors, crossbreeding, selection of segregating populations and preliminary yield trials were conducted by the International Center for Maize and Wheat Improvement, and the performance trials quality evaluations, purifications and phenotypic characterization were carried out by the Institute National Agricultural and Livestock Forestry Research at CENEB, located in the Yaqui Valley, Sonora. The comparisons of yield and quality were made since 2011 with respect to CIRNO C2008, which has been the most planted variety in Sonora in recent years, but it lost its resistance to leaf rust and lacks color in the semolina. produces. CENEB Oro C2017, was registered in accordance with the Federal Seed Certification and Marketing Act in force in Mexico and has the definitive registration TRI-146-231117 of the National Catalog of Plant Varieties of the National Inspection and Certification Service of Seeds and the breeder’s title with registration number 1897.
