UY = unhusked yield, HY = husked yield, EN = ear number, AD = anthesis date, EH = ear height, EL = husked ear length, ED = husked ear diameter, 1^ST = the first ear position, 2^nd = the second ear position, 2^ndM = the number of the marketable ear at the second ear position. KKR = at Khon Kaen in the rainy season 2019, UTR = at Uthai Thani in the rainy season 2019, KKD = at Khon Kaen in the dry season 2018/2019, UTD = at Uthai Thani in the dry season 2018/2019. Means followed by different letters within the same row are significantly different based on LSD at .
