Abstract
玉米族群ETO Illinois C6之219個同親兄妹後裔進行評估試驗，其平均開花期為76.3天，穗位高96.4公分，株高204.0公分，公頃子實產量8.02噸。開花期、穗位高、株高及產量之變異係數依序分別為3.3、10.7、6.0及17.2％。四個性狀之遺傳變方均達顯著。廣義遺傳率方面，開花期為66.2％，穗位高20.2％，株高42.7％，產量36.8％。ETO Illinois為CIMMYT分離抗普通型銹病及煤紋病基因之重要族群之一，含有相當多的遺傳變異量，適應本省栽培環境，具高產潛力，將之納入育種計畫對本省飼料及青割玉米之改良應有助益。
Evaluations of 219 full-sib progenies of maize population ETO Illinois C6 were conducted at Taiwan Agricultural Research Institute. For days to flowering, ear height, plant height, and grain yield, mean values were 76.3day, 96.4cm, 204.0cm, and 8.02t/ha, respectively. Coefficients of variation of the four traits were 3.3, 10.7, 6.0 and 17.2%, respectively. Heritability estimates were 66.2, 20.2, 42.7 and 36.8% for days to following, ear height, plant height, and grain yield, respectively. ETO Illinois is one of the most important populations in CIMMYT for segregating for resistance to Puccinia polysora and Helminthosporium turcicum. This results indicated that population ETO Illinois contains amount of genetic variation. Its good adaptation and high-yield potential may be useful for improvement of field corn and forage corn in Taiwan.
