In the present study, we examined the phenotypic diversity of Greek garlic (Allium sativum L.) genotypes using morphological descriptors derived from IPGRI and UPOV. Thirty-four garlic genotypes were cultivated at two different locations: (a) Velestino, Magnesia, Region of Thessaly, and (b) Kavasila, Ilia, Region of Western Greece. The garlic genotypes were characterized using twenty-seven morphological descriptors and four quantitative characters, namely bulb dry matter, chlorophyll content in the leaf, yield and total soluble solids (°Brix) of plants and raw bulbs. The Shannon–Weaver (H′) phenotypic diversity index varied among the genotypes, although identical mean values (0.79) were recorded for both fields. Traits, such as flowering stem length, bulb skin color, skin color of the clove presented low (H′) values indicating a high coefficient of heritability and less environmental effect. Principal component analysis based on morphological characters showed that the first seven axes could explain 71.49% and 75.86% of total variation for Kavasila and Velestino fields respectively. Significant differences were also observed among the garlic genotypes for the quantitative characters studied. Furthermore, significant statistical correlations were recorded for specific characters between the two cultivation sites e.g. yield with weight of cloves (r = 0.55 and r = 0.62) and number of cloves per bulb with weight of cloves (r = −0.51 and r = −0.55), which could be exploited further in future breeding programs. In conclusion, the high phenotypic diversity observed among the garlic genotypes could be attributed to various factors such as the genotype, the cultivation practices and the environmental conditions. 

Daily Garlic packhouse hygiene checklist

U.S. No. 1 consists of garlic of similar varietal characteristics which is mature and well cured, compact, with cloves well filled and fairly plump, free from mold, decay, shattered cloves, and from damage caused by dirt or staining, sunburn, sunscald, cuts, sprouts, tops, roots, disease, insects, or mechanical or other means. Each bulb shall be fairly well enclosed in its outer sheath. Unless otherwise specified, the minimum diameter of each bulb shall be not less than 1-1/2 inches.
a. Tolerances. In order to allow for variations incident to proper grading and handling, the following tolerances, by weight, are provided as specified:
1. For defects. Ten percent for garlic in any lot which fails to meet the requirements of this grade, including therein not more than 2 percent for garlic which is affected by decay.
2. For size. Five percent for garlic in any lot which fails to meet any specified size.

Garlic Quality control & management

Garlic-specialized metabolites contribute to both spicy flavor and healthy function of garlic. Their accumulation pattern and regulatory mechanism vary greatly at different environments and maturities. Herein, metabolomics models were built to evaluate and predict the quality and chemical composition variances of four garlic varieties in two regions at six growth stages. A total of 91 metabolites were identified, and their accumulation pattern during growth in three varieties of garlic in Shandong was similar but obviously distinct from that planted in Heilongjiang. Active metabolism for organosulfur compounds and amino acids was observed, and most metabolites with the “γ-glutamyl-” group were the storage compounds of nitrogen and sulfur in garlic because they increased remarkably during growth. The levels of functional components in garlic varied among different stages, and reliable prediction models for these compounds were provided, which may give a new idea for the estimation of garlic quality and confirmation of the best harvest time.
