CASHEW VARIETAL STUDY AND SELECTION IN THE NORTHEAST, THAILAND
Cashew varietal studies and selection were undertaken in various locations of Northeastern Thailand to identify varieties of high yield and good nut quality. Data on tree growth and development, yield and kernel quality have been recorded at three plantations for 11 years. Ten promising trees were selected and two of them, SK 5–1 and SK 5–10, were officially released in 1987 and renamed as certified varieties, Sisaket 60–1 and Sisaket 60–2 respectively. These varieties have high yield with big nut size, good kernel quality (average grade 3 of the world market) and high sunken seed and high shelling percentages. Ten selected trees were used as maternal clones for 91 hectare of seed gardens establishment to produce a composite seed variety, Sisaket-A.
