“…It is not interest or competence that is in doubt, but rather economic viability. Good reports of farmer interest are on record from: China, a pioneer in the field (Bofu et al, 1987;Li & Shen, 1980): Vietnam (Hoang et al, 1988): India (Upadhya, 1980, 1990: Upadhya et al, 1985: Bangladesh (Anon., 1995a): Indonesia . By contrast, there seems to be no prospect of major success in temperate countries, nor any obvious reason why there should be, since superior clones are readily available (see Almekinders et al.…”

“…In the previous paragraphs several Asian countries in which seed-grown potatoes had been seriously investigated were mentioned. Leading countries, making the transition to actual commercial production are: China (the pioneer), Vietnam (where the crop alternates with rice on low ground and is claimed by Hoang et al (1988), to be the biggest producer in the world) and India (which is likely, according to Upadhya and to Khatana (1996) to become the leading commercial producer in coming decades, with an area well in excess of one Mha). Bangladesh seems to be on the brink of commercial exploitation and already has a substantial domestic production of potatoes from very poor quality clonal stocks (Anon., 1995a).…”

SummaryThe vast majority of cultivated potatoes are vegetatively propagated, outbred autotretraploids. Disease problems dominate the maintenance of vegetative stocks. There have been recent proposals to propagate the crop by sexual seed in order to evade some of those disease problems. Some success has been achieved but controlled crosses are necessary fo avoid inbreeding depression and seed propagation is not as cheap or simple as had been hoped. The idea has evoked wide interest throughout the tropics and has had some (and increasing) practical impact on China, India and Vietnam. There is a strong tendency to use ~tuberlets' borne on crowded nursery plants rather than to grow true seedlings. Some seedling families have looked locally attractive but it is not always realised that to use them implies the abandonment of about half the genetic variation, a heavy price to pay for disease avoidance. There is emerging recognition that vegetative and seed propagation are complementary rather than competitive and that good breeding programmes will therefore serve both. This review concentrates upon genetic/plant breeding aspects of propagation by seed, a subject hitherto largely neglected in the literature.

“…Large quantities of open-pollinated (OP) berries may be easily harvested from potato clones growing in farmers' fields in many such regions (Hoang et al, 1988). Given time, this OP seed will produce high yields of seedling tubers in some genotypes because the conditions during seedling emergence are optimized for this purpose.…”

“…True potato seed (TPS) has been suggested as an alternative seed source for potato production, particularly in countries where the use of conventional seed tubers is hampered by large storage losses (Hoang et al, 1988) or infestation with tuber transmitted diseases (Bofu et al, 1987;Fernandez et al, 1988), because TPS carries few pathogens especially viruses from season to season (Malagamba et al, 1983;Burrows and Zitter, 2005). About 2 tonnes of seed tubers which also represent food is required to plant in one hectare which can be replaced by 100-150 gms TPS (Rowell et al, 1986;Mahmood, 2005).…”

Potato is one of economically important crop in Ethiopia. However, the average yield is far below the potential due to many challenges like lack of improved variety and quality seed potatoes. True potato seed is alternative seed source for potato production with many advantages, particularly where seed tubers is hampered by diseases. TPS used in Ethiopia, is negligible but it is likely to gain thrust in future particularly where quality seed tubers are either not available or expensive. Therefore, this study was conducted to evaluate the performance of potato varieties established by open-pollinated TPS seedling for yield and yield components. Eight potato varieties (Local, Bulle, Challa, Dagim, Gudanie, Jalenie, Shonkolla and Zengena) were established by open-pollinated TPS seedling for yield and yield components. The experiment laid in Randomized Complete Block Design with three replications. The results revealed that a significant variation in most traits was observed. The highest plant height (118.87cm) was recorded from Zengena. Bulle scored the highest marketable, unmarketable, total tuber number and marketable tuber yield per hill was 25.31, 26.03, 51.34 and 1.1117kg respectively. Local scored the highest tuber weight (1.2949 kg hill-1) and tuber yield (54.44 ton ha-1) but not significant different with Bulle, Gudanie, Dagim and Challa varieties due to its highest unmarketable tuber yield (0.3296 kg hill-1). The result of the study reviled that the open-pollinated potato varieties established through TPS have a great influence on yield and yield components of potato. Bulle variety has been recommended in all yield and yield components than others.
