Abstract

Quinoa (Chenopodium quinoa Willd.) is a crop that grows under conditions of environmental stress, has high nutritional value, and agronomic potential. It is grown and marketed on a small scale in Mexico. However, there are no varieties or technology for its production. The objective of this research was to determine the performance of quinoa germplasm in the Central high-valley lands of Mexico. Sixteen genotypes of different origins and characteristics were evaluated in three environments in the localities of Nanacamilpa, Tlaxcala; and Santa Lucía de Prías, Texcoco, State of Mexico. Statistical differences (p ≤ 0.05) were found for genotypes. Late genotypes Suyana, Suma, Pata de Venado, Blanca Ayacucho, and Huauzontle showed higher grain yield (4004.9, 3888.3, 3091.1, 2999.7, and 2967.2 kg ha-1, respectively). Among the intermediate genotypes, Tokio rosa and Pasankalla reventona were the better with 2858.4 and 2118.4 kg ha-1, respectively. Whereas among the early genotypes, Tarpuna had the highest grain yield (3005.8 kg ha-1). Regarding seed diameter, only Huauzontle and Quinoa negra had a seed size equal to or smaller than 1.8 mm; the rest of the genotypes can be marketed as grains because of their seed size. Of the environments evaluated, the least favourable was Nanacamilpa 2019, while Santa Lucía de Prías 2019 was the most favourable environment. Overall, the performance of the evaluated genotypes was as expected, as they mostly come from the Inter-Andean Valleys region, which are very similar in altitude and temperature to the Central high-valley lands of Mexico.

墨西哥中部高河谷地区环境中藜麦种质资源评价
藜麦(Chenopodium Quinoa wild .)是一种在环境胁迫条件下生长的作物,具有很高的营养价值和农艺潜力。它在墨西哥小规模种植和销售。然而,它的生产没有品种和技术。本研究的目的是确定藜麦种质资源在墨西哥中部高谷地的表现。在特拉斯卡拉省纳纳卡米尔帕省的3种环境中对16种不同来源和特征的基因型进行了评价;和Santa Lucía de Prías,德州,墨西哥。基因型间差异有统计学意义(p≤0.05)。晚期基因型Suyana、Suma、Pata de Venado、Blanca Ayacucho和Huauzontle的籽粒产量较高(分别为4004.9、3888.3、3091.1、2999.7和2967.2 kg ha-1)。在中间基因型中,东京月季和长春花分别以2858.4和2118.4 kg ha-1表现较好。而在早期基因型中,塔普纳产量最高(3005.8 kg hm -1)。在种子直径方面,只有花豆和藜麦的种子大小等于或小于1.8 mm;其余的基因型可以作为谷物销售,因为它们的种子大小。在评估的环境中,最不利的是Nanacamilpa 2019,而Santa Lucía de Prías 2019是最有利的环境。总体而言,所评估基因型的表现与预期一致,因为它们大多来自安第斯山脉间山谷地区,该地区的海拔和温度与墨西哥中部高山谷地区非常相似。

期刊介绍: AGROCIENCIA is a scientific journal created and sponsored by the Colegio de Postgraduados. Its main objective is the publication and diffusion of agricultural, animal and forestry sciences research results from mexican and foreign scientists. All contributions are peer reviewed. Starting in the year 2000, AGROCIENCIA became a bimonthly and fully bilingual journal (Spanish and English versions in the same issue). Since 2007 appears every month and a half (eight issues per year). In addition to the printed issues, the full content is available in electronic format.
