GD

The two-character ISO 3166 country code for GRENADA.

GD

1. ISO 3166-1 alpha-2 code for Grenada. This is the code used in international transactions to and from bank accounts in Grenada.

2. ISO 3166-2 geocode for Grenada. This is used as an international standard for shipping to Grenada. Each parish in Grenada has its own code with the prefix "GD." For example, the code for the Parish of St. Andrew is ISO 3166-2:GD-01.

Abbreviations: AFLP, amplified fragment length polymorphism; COP, coefficient of parentage; GDE, genetic diversity estimate; HRS, hard red spring; HRW, hard red winter; HWS, hard white spring; MDS, multidimensional scaling, PCR, polymerase chain reaction; PNW, Pacific Northwest; RAPD, random amplified polymorphic DNA; RFLP, restriction fragment length polymorphism; SC, spring club; SWS, soft white spring; SWW, soft white winter; UPGMA, unweighted pair-group method arithmetic average; WC, winter club.
Since GDE values potentially range from 0 to 1, the distributions in Fig.
Cluster analysis of both GDE matrices suggests HRW and WC gene pools were the most narrow, whereas the diversity range was greatest in the SWS and SWW market classes.
A significant, positive ([r.sub.s] = 0.42, P [is less than] 0.001) association was detected between the two GDE matrices.
GDEs between hexaploid and diploid genotypes were higher than within the hexaploid material, as evidenced by examining banding patterns in Fig.
Comparisons of mean GDEs also were made within and between market classes (Table 4).
All diversity analyses were based on the combined data from both restriction enzymes, since PstI and EcoRI GDEs were significantly correlated, and the combined data matrix minimized MDS error terms and maximized variation accounted for by the AMOVA.
The 1/0 data matrix yielded 1540 pairwise genetic diversity estimates (GDEs), calculated as 1 - Jaccard's Similarity Coefficient [1 - a/(n-d)], where a = number of fragments in common between two cultivars, n = total number of fragments scored, d = number of fragments absent in both cultivars (Rohlf, 1993).

Clusters of two or three cultivars with a mean GDE less than 0.33 were generally supported by [is greater than] 50% of the bootstrap data sets; however most larger clusters, especially core market class (HRS, SWS, HRW, SWW) and growth habit clusters were supported by less than 10% of the bootstrap trees.
When evaluating diversity levels, it is important to consider that GDE calculations disregarded monomorphic bands to ease computation.
