| Abstract | The evaluation of waxy corn hybrids aimed to evaluate the yield potential of elite waxy corn hybrids in multi-environment. A Randomized complete block design was conducted with three replications, consisting of six elite waxy corn hybrids and three commercial waxy corn hybrids, including Chai Nat 2, Ploychompoo and Sweet violet. The experiment was conducted in ten environments at Kanchanaburi, Khon Kaen, Lopburi, Sukhothai, Loei, Song Khla, Suphanburi and Ubon Ratchathani, including two environments at Chai Nat province during 2022-2023. The combined analysis of variance found that two elite waxy corn hybrids had the highest yield that were CNW2182 and CNW2082, providing yield with husk of 2,180 and 2,165 kg/rai. There was no significant difference from Sweet violet (2,124 kg/rai) which was the highest yield of check variety. For GGE biplot analysis, the results showed that the biplot explained 82.87% of total variation with PC1 of 58.29% and PC2 of 24.58%. CNW2182 had high yield and high stability which was higher than Sweet violet. Additionally, there were significantly high yield in five environments. Moreover, two elite waxy corn hybrids, CNW2182 and CNW2082 had yield without husk of 1,313 and 1,293 kg/rai and good agronomic traits, including the number of days to harvest of 65 and 63 days that less than Sweet violet, ear size (diameter x length) of 4.6 x 16.3 and 4.4 x 16.9 cm, number of seed row per ear ranged of 14-16 rows and good eating quality. Thus, two elite waxy corn hybrids could be further recommended to farmers. |
