Résumé
At the present time the breeding, the establishment and manegement turf, face the world challenge of availability ; The use of native species with potential for low maintenance has become the viable option in many countries before this problem. Aware of this panorama, we see a great opportunity for the adoption of native species with turf potential in Mexico ; like it is the case of the Buffalograss (Buchloe dactyloides (Nutt)), specie that is recognized as the best ecological turf in USA. In that context, this study was carried out to evaluate the turf quality of Buffalograss in Saltillo, Coah., representative area of the semi-arid region of Mexico. 15 genotypes of the Buffalograss were used : 7 materials obtained from Turfgrass Breeding Program of the University of Nebraska and 8 materials collected in the southern region of the state of Coahuila. _ The general objective of this work, besides evaluating the quality of grass of this species like a turf and with it to identify the superior materials for this characteristic, it was to compare the behavior of the USA genotypes with that of the Mexicans This experiment was established in the 2000 and the evaluation of turfgrass quality was carried out in the year 2002, seven characters were considered for to define the turf quality : 4 quantitative characters (wide and limbo longitude, density and plant height) and 3 qualitative characters (Quality, ground cover and aerial cover). _ For the statistical analysis a random block design was used with 3 repetitions and 15 treatments. To supplement this study, three contrast were carried : The first one to compare the 8 genotypes of Mexico with the 7 genotypes of USA. ; the second contrast consisted on the comparison of each one of the materials of Mexico with the genotype Alltex, the third contrast was carried out comparing each one of the materials of Mexico with the genotype 86120. It is necessary to mention that these 2 American materials, are representative for the southern region and nothern-central region of USA respectively. Finally LSM comparisions were carried out these were identifying the best genotypes.. _ The results obtained in the ANoVAS, indicated that statistical differences exist among the 15 genotypes in the seven valued characters ; on the other hand, the realized contrasts demonstrated the superiority of the Mexican materials over the Americans, regarding turf quality. The LSM test identified the superiority of Mexican genotypes as : B-7, B-9 B-20 and B-22. Based on this information, it was concluded that Buffalograss is a god option to be use as a turfgrass in the semi-arid region of Mexico.
