Plantlets and seed procurement
Seed orchards are a common method of mass-multiplication for transferring genetically improved material from breeding populations to production populations (forests) and in this sense are often referred to as “multiplication” populations. A seed orchard is often composed of grafts (vegetative copies) of selected genotypes, but seedling seed orchards also occur mainly to combine orchard with progeny testing. Seed orchards are the strong link between breeding programs and plantation establishment. They are designed and managed to produce seeds of superior genetic quality compared to those obtained from seed production areas, seed stands, or unimproved stands.
In first generation seed orchards, the parents usually are phenotypically-selected trees. In advanced generation seed orchards, the seed orchards are harvesting the benefits generated by tree breeding and the parents may be selected among the tested clones or families. It is efficient to synchronize the productive live cycle of the seed orchards with the cycle time of the breeding population. In the seed orchard, the trees can be arranged in a design to keep the related individuals or cloned copies apart from each other. Seed orchards are the delivery vehicle for genetic improvement programs where the trade-off between genetic gain and diversity is the most important concern. The genetic gain of seed orchard crops depends primarily on the genetic superiority of the orchard parents, the gametic contribution to the resultant seed crops, and pollen contamination from outside seed orchards
In addition to our seed orchids we contract farms for Seed Procurement to ensure quality input for maintaining a sound system for effective distribution of quality seed. The greater emphasis has to be placed on procurement ensuring compliance with the set best industry practices for production and multiplication of seed.
Plantations International created a means by engaging growers with large scale cultivatable area to multiply and produce certified seed, engage growers after survey of their properties by virtue of a legal binding agreement. These growers after registration with the Plantations International are provided with basic seed of major crops for multiplication and production of certified seed. The quality and purity of the seed is tested ad monitored at various stages by the continuous involvement of Plantations International. The certified seed produced by the grower is purchased by Plantations International at the rate agreed in the agreement for future supply.
The achievement of high crop yields is indirectly dependent upon the stringent controls exercised over the purchased quantities to ensure that they are free of inert matter and waste. The procurement department of Plantations International is vested with the responsibility to purchase high quality seed with the lowest percentage of inert matter. The variety wise procurement target is on the basis of demand and supply position of the relevant crop and approved by the committee.
