The loss of agrobiodiversity is a topic of global impact. On a local scale, Lombardy, in the Alpine macro-Region, has lost more than 78% of its plant agrobiodiversity. Only four maize (Zea mays L. subsp. mays) landraces of Lombardy are registered in the European Register of Conservation Varieties. However, there are other maize landraces in Lombardy such as “Mais delle Fiorine”, which was characterized from an agronomic, morphometric, nutritional and genetic point of view in this research and then compared with the four other landraces already registered (“Spinato di Gandino”, “Rostrato Rosso di Rovetta”, “Scagliolo di Carenno” and “Nero Spinoso”). “Mais delle Fiorine” resulted richer in starch (81% ± 1.6) and zinc (35.8 ± 9.1 mg Kg⁻¹) and lower in phosphorus (3256.7 ± 204.2 mg Kg⁻¹). The kernels in the five landraces also differ in the mean shape that is obovate without beak. A genetic distinction between “Mais delle Fiorine” and the other varieties was observed, and in particular compared to “Nero Spinoso”, while “Scagliolo di Carenno” and “Rostrato Rosso di Rovetta” showed great similarities. As regards agronomical trials, “Mais delle Fiorine” can grow from the Po Valley (90 m a.s.l.) to the mountain environments of the Seriana Valley (also over 900 m a.s.l.) without significant differences in grain yield. In addition, this landrace would seem able to tolerate environments where there is a greater probability of water stress.

农业生物多样性的丧失是全球影响的话题。在当地，伦巴第大区的高山地区已经丧失了超过78％的植物农业生物多样性。伦巴第地区仅有四个玉米（Zea mays L. subsp。mays）地方品种在欧洲保护品种注册中进行了注册。但是，伦巴第地区还有其他玉米地方品种，例如“ Mais delle Fiorine”，在本研究中从农业，形态，营养和遗传学角度对其进行了特征鉴定，然后与已经注册的其他四个地方品种进行了比较（“ Spinato di Gandino ”，“ Rostrato Rosso di Rovetta”，“ Scagliolo di Carenno”和“ Nero Spinoso”）。“ Mais delle Fiorine”产生的淀粉（81％±1.6）和锌（35.8±9.1 mg Kg ^-1）更丰富）和较低的磷（3256.7±204.2 mg Kg ^-1）。五个地方品种的籽粒的平均形状也不同，它们呈倒卵形而没有喙。观察到“ Mais delle Fiorine”和其他变种之间的遗传差异，特别是与“ Nero Spinoso”相比，而“ Scagliolo di Carenno”和“ Rostrato Rosso di Rovetta”表现出极大的相似性。关于农艺试验，“ Mais delle Fiorine”可以从Po谷（90 m asl）生长到Seriana谷的山区环境（也超过900 m asl），而谷物产量没有显着差异。此外，这种地方品种似乎能够忍受水分胁迫可能性更大的环境。
