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.

Reception date: October 2018

Acceptance date: November 2018

The most important phenotypic characteristics for the description of this variety, according to the guidelines of the International Union for the Protection of New Varieties of Plants (UPOV), CENEB Oro C2017 presents a strong anthocyanin coloration in coleoptile, the growth habit in the stems it is erect and with very low frequency of plants with curved flag leaf.

The spike of parallel edges, is dense and its length is medium. In the middle third of the spike the shoulder of the glume is narrow and inclined, with a median tip. The glume is oblong in shape with no villi on the outer surface. The amber grain is semi-elliptical in shape, with short length of the villus of the grain brush in dorsal view and when treated with 1% phenol it does not show coloration. It is a plant that is characterized by its short size and is slightly precocious (Figure 1).

Performance and industrial quality involve parameters controlled by genetic, environmental and management factors Alvarado et al. (2018). These variables were evaluated during six years in the CENEB, starting from the agricultural cycle 2011-2012 until the 2016-2017 cycle. The results obtained indicate that the performance of CENEB Oro C2017 equals the average performance of the CIRNO C 2008 control with 5.9 tha-1 when handled with four irrigation risks.

But the new variety exceeds the control by 250 kilos when they undergo restricted irrigation (Table 1). Given the limited availability of water in the dams in Sonora, mainly in the Valley of the Mayo and before a need to reduce the volumes of water in the wheat crop, CENEB Oro C2017 is considered an option for the sustainability of the wheat crop in Sonora (Chávez et al., 2017).

In the Table 2 shows the indicators of industrial quality compared with the control, obtained from 12 evaluations per year. The milling industry for the extraction of semolina and the pasta manufacturer require producing varieties. Of a grain with a high specific weight, to guarantee a high extraction rate. A high protein content that ensures the integrity of the pasta cooking. And a yellow index, much desired by the final consumer. CENEB Oro C2017 averaged a specific weight of 82.1 kg hL-1, 12.4% protein in grain and a pigment value of 26.5 points on the ‘b’ scale of the Minolta equipment (Table 2).

The INIFAP-CENEB maintains the original and basic seed categories of this variety (Figure 2). The registered and certified seed will be increased in the 2017-2018 cycle by the Board of Agricultural Research and Experimentation of the State of Sonora (PIEAES, AC).

Conclusions

CENEB Oro C2017, is considered an option for the sustainability of the wheat crop due to its behavior with reduced irrigation and to improve the yield of crystalline wheat in the south of Sonora, where the environmental conditions that prevail during the wheat cycle are suitable for incidence of leaf rust, foliar disease caused by the fungus Puccinia triticina, to which CENEB Oro C2017 showed resistance until the 2016-2017 cycle. In addition, CENEB Oro C2017 represents an option for exporters of crystalline wheat because of the intensity of the yellow color in its semolina.

Acknowledgments

The authors would like to thank INIFAP for the partial financing of the research and validation work that led to obtaining the CENEB Oro C2017 variety. To CIMMYT, for providing the advanced line from where the variety originated. And to the technical staff of the Wheat Genetic Improvement Program of the Norman E. Borlaug Experimental Field.
