| Abstract | Sukhothai Horticultural Research Center and Phichit Agricultural Research andDevelopment Center conducted a sweet potato breeding program in order to select newvarieties which have good quality for fresh consumption and high yield. Crossing betweenlocal cultivars and introduced cultivars has been done. The hybrids were evaluated andcompared with the local cultivars. The top six hybrids were selected and tested under3 different locations (regional trial) to compare quality and yield. Three promising hybridlines (ST 03, ST 10 and ST 18) were selected and tested in 6 farmer plots. Growth, yield,quality and consumer acceptability of those lines were record and compared with localcultivar. The results showed that ST 03 and ST 18 were suitable for fresh consumption.ST 03 had high growth rate, enable it to cover the ground faster which prevent theproblem from weed. It tolerated to sweet potato weevil better than other cultivars. Whiteskin and yellow flesh with good eating quality were found in ST 03. Those average yieldfrom regional trial and farmer plots were 3,884 and 1,619 kg/rai, respectively. ST 18 grewwell with red skin, yellow flesh and good eating quality. It also contained high betacarotene (480 ?g) and protein (1.2 g) per 100g of fresh sweet potato. The average yieldfrom regional trial and farmer plots were 2,900 and 1,727 kg/rai, respectively. ST 03 andST 18 cultivars are recommended to farmers to replace the local cultivars. |
