The experiment was using randomized complete block design with two replications. The result showed that the best three hybrids were KKU42 x T1 UP19 x KKU42 and UP10 x KKU59. They were expressed in green weight, 2,404.8 2,404.6 and 2,747.5 kg/rai, respectively. Meanwhile, the white weight was 1,606.5 1,606.1 and 1,834.6 kg/rai, respectively. Moreover, the eating qualities found that scoring equal to 2.0 2.2 and 2.3. The comparative varieties, green and white weight were averaged 2,547.6 and 1,835.1 kg/rai. Also, the eating quality was scored equal to 1.7. However, the sixty hybrids have remained selected goal, then, there are testing on-farm trial in the upper Northern parts dry season
