Studies on the Field Use of Potato True Seeds in Tuber Production

Abstract

Several cultural experiments were conducted to investigate the most adapt ye method of using potato true seeds (TPS) in potato production. 1. Comparison between the use of true seeds and seed tubers. 2. Comparison of different seeding rates in relation to tuber yield. 3. Comparison of TPS tubers of different size in their ability as seed tubers. 4. Comparison of yielding ability of different TPS populations. All plantings were adversely affected by extended period of heavy rainfall during the later part of the growth. However, results are summarized as follows 1. All yields obtained from TPS seedling-whether by direct seeding or by transplanting, were lower than those obtained from tuber planting. 2. Potatoes produced from true seeds can be used as seed tubers to produce a crop as long as the tuberlets reach the size of 8g. The technology of direct seeding with dense spacing can be employed to produce numerous small tubers in limited land. 3. Direct seeding is more economic and labor-saving than transplanting in producing tubers.
