The dynamics in market level prices was examined for Philippine copra trading. The analysis of the price formation process in the copra miller-dealer-farmer markets showed that a weak form of market integration characterized the trading of copra resecada between dealers and millers in all Philippine regions. In contrast, integration of any form was absent between miller-farmer and dealer-farmer in all regions except in Region V. Likewise, no integration was noted in all market levels when dealers and millers used copra resecada price while farmers were given the copra corriente Pasa price. Important factors were identified that contributed to the level of market integration. Recommendations made encompass areas on coconut production and productivity, market infrastructure and facilities, and pricing system in copra trading.

Increased genotypic heterozygozity through phenotypic disassortative mating improves vigor and yield performance of progenies, while inbreeding causes depression, thus the use of F2 seeds from F1 variety hybrids could lead to disastrous results. Knowing the partiality of coconut farmers in using seeds from any high yielding variety for successive cropping, the development of an open-pollinated variety or OPV with a high degree of balanced heterozygozity is highly desired. Started way back in 1979, the PCA pioneered the development of a synthetic coconut variety, i.e., PCA SYN VAR 001. With some modifications of the classical breeding method, a scheme was formulated to produce the base population of a synthetic coconut variety using single crosses from six tall coconut cultivars, four local and two foreign tall varieties, which were found to possess good general combining ability (GCA). Field planting of the F1 base populations was done in September 1992. Since then, observations on growth and development, flowering and early yield of the genetic materials, as well as the distributions of “bulked” seeds from the plantation are ongoing. The use of modern molecular marker tools, i.e. microsatellite or Simple Sequence Repeat (SSR) marker technology in the development of the synthetic variety of coconut, including the status of the research undertakings and prospects of the new breeding populations are described in this paper.

To generate indicative information and knowledge on productivity and production economics in growing coconuts, two known hybrids of coconuts in the country are considered in this review. These are: Catigan dwarf x LAGT (PCA 15-1) hybrid; and Malayan red dwarf x BAYT (PCA 15-3) hybrid, tested earlier at the genetic and performance blocks of Zamboanga Research Center of Philippine Coconut Authority (PCA-ZRC), an intermediate growing zone of coconut, coastal-flat area of Western Mindanao. Relevant data from field establishment, maintenance and yields of palms for first 15 years from field-planting (FP) are used in this ex-ante enterprise budgeting and net present value or NPV analyses, considered as practical tools for decision-making in coconut farming and agribusiness. Depending on the planting material used and farm gate copra price levels (Php 10–24/kg), initial harvest year (4 – 5 years), average annual nut and copra yields at early full-bearing and full-bearing stages, the following profitability indices all differed between the two hybrids: annual gross returns and net returns, net present value (NPV), benefit-cost ratio or BCR, and internal rate of return (IRR %). At mature full-bearing stage, annual yields ranged 2.5 – 4.3 tons copra/ha (135 trees). Using a copra price level of Php 16/kg: the average annual net returns at full bearing stage (10-`15 years) reached PhP23,900 – 44,100 (PCA 15-1) and PhP18,500 – 72,200 (PCA 15-3) and NPV (18% interest) at PhP 20-24/kg copra of PhP 26,340 – 41,641(PCA 15-1) and PhP34,288 - 58,304 (PCA 15-3); and BCR of 1.24 and 1.48 and 1.40 – 1.68, for PCA 15-1 and PCA 15-3, respectively. Overall, varietal productivity, long-term sustainability and profitability or economic indices indicate that the logical selection option identified follows: PCA 15-3 > PCA 15-1. (PhP 48.70 = US$1). Implications on coconut planting/replanting, palm productivity and profitability as influenced by the different planting materials are discussed with respect to policies in coconut industry development.
