Derivation: r. AMAZonas.
Collected by INIAP/UWI Chalmers.
Location: R. Amazonas nr Iquitos, Ecuador.
(Chalmers, 1973a [CHA73A]) AMAZ 3 [CHA] to AMAZ 10 [CHA] and AMAZ 15 [CHA] were selected from a planted area of cocoa with trees showing a range of pod types from five pairs of very distinct, slightly rugose ridges to a very smooth ridgeless calabacillo type. Most had a slight bottleneck and several had a pronounced "blanco" foundation colour. Several pods showed a very characteristic slightly rough, minutely pimpled surface. Some had a very hard pod wall (AMAZ 5, 7 and 8 [CHA]). The number of seeds per pod varied between 11 and 49. All the seeds were dark purple, generally small to medium in size and, within the same pod, plump and flattish seed occured. Only AMAZ 3 [CHA] and AMAZ [15] showed any Witches broom infection. AMAZ 11and AMAZ 12 were collected from Iquitos island, where Pound collected the IMC family. Many of the trees growing in the farm had pods very similar to those of IMC 67 although AMAZ 12 had a more Amelonado shaped pod with a fairly hard shell. AMAZ 13 [CHA] and AMAZ 14 [CHA] had marked pigmentation in the flush. The peduncles were pigmented but not the stamens. The young pods were smooth and Amelonado shaped. The petioles were distinctively short, thick and without any constriction.
Notes: Collected in 1973.
