中文摘要 | 臺南21號命名前代號為 PFH 83-9,屬單雜交種,其系譜為 P-1212 × CI-8122,母本 P-1212 係自 Pioneer 種子公司引進品種 Pioneer 3208 分離選育出之自交系,屬溫布型淡黃色半硬粒種,具有抗露菌病,普通型�蚽f(包括幼苗期及成株期)、幼苗期南方型�蚽f及輪生期螟害等特性。父本CI-8122為自國際玉米及小麥改良中心(CIMMYT)引進綜合品種Mcy-51分離篩選培育出之品系,屬熱帶型白色馬齒種,具有抗露菌病、莖腐病及�蚽f(包括南方型及普通型�蚽f)等特性。PFH83-9於84年秋作品質分析與莖稈硬度測試後,由各項結果顯示,PFH 83-9鮮草產量高而穩定,並具有抗露菌病、莖腐病、病毒病、�蚽f(包括南方型及普通型�蚽f)、輪生期螟害及倒伏等特性、營養成分及青貯品質均佳,適合推廣供養殖乳牛芻料。本品種適合雲嘉南及花東地區、灌排水良好及 pH 值在 5.5∼8.0 間之壤土磷酐及氧化鉀分別為 90 公斤及 60 公斤。PFH 83-9 於88年5月18日經農林廳召集之作物新品種命名審查會通過命名為臺南 21 號。 |
英文摘要 | Tainan No.21 is a single cross forage corn hybrid. It was coded as PFH 83-9 before registration. Its pedigree is P-1212×CI-8122. The maternal line P-1212 was bred from Pioneer 3208 introduced from Pioneer Seed Company in the United Sates. It is endowed with pale yellow semiflint kernel. P-1212 is also characterizied with highly resistance to downy mildew Peronoscleroshora sacchari and moderate resistances to common rust disease puccinia sorghi and whorl stage corn borer Ostrinia furnacalis feeding damage. The paternal line CI-8122 was derived from a composite Mcy-51 introduced from CIMMYT. It is characterized with white dent kernel and highly resistance to stalk rot Pythium aphanidermant and rust disease (P. sorghi and P. polysora) and moderate resistances to downy mildew P. sacchari. Since being selected out in fall crop of 1995 PFH 83-9 was recommended to participate in islandwide yield trial for newly developed forage corn hybrids, effect test on nitrogen rate and plant density, resitant test to major economic important disease and insect pests, stalk quality test as well as chemical analysis for nutrition composition in mature plant and silage quality. The data collected from above tests indicated that PFH 83-9 is characterized with stable highyielding ability, resistance to downy mildew, stalk rot, rust disease, corn borer feeding damage in whorl stage and lodging, it is also possessed with high nutrition in mature stage of plant development and good silage quality. These revealed that PFH 83-9 could be adopted for cultivating in eastern part area as well as Yu-Chia-Nan area in the country and used as feed for dairy cattle industry. After being evaluatebd by the meeting of the Registration Committee for new crop cultivar convened by the Department of Agriculture and Forestry, Taiwan provincial government PFH 83-9 was officially named as Tainan No.21 on May 18, 1999. the proper plant density for Tainan No.21 is 66,666 plants per hectare, the recommended amount of N、P�烙�ㄐBK�Μper hectare is 150-200kg、90kg and 60kg, respectively. |
