中文摘要 | 食用白玉米新品種臺南22號命名前代號為 PWH 81-2,屬單雜交種,其系譜為TN 2661×PD 3732,母本TN 2661係自臺南地區蒐集之臺南白玉米族群培育出之自交系,屬白色半硬粒種,其吐絲期比父本開花期早2-3天。不抗露菌病、莖腐病及普通型與南方型�蚽f,但對病毒病中抗。公頃籽實產量2,038公斤,父本為自屏東地區蒐集之臺南白玉米族群分離純化選育出之品系,屬白色半硬粒種,對露菌病及病毒病中抗,對莖腐病及普通型與南方型�蚽f為抗。公頃籽實產量2,186公斤。PWH 81-2於1994年春作選育出,經選拔參加全省性區域試驗,氮素及栽培密度、磷、鉀肥與網室栽培密度試驗、品質分析及官能品評與病害抗性檢定,結果顯示 PWH 81-2 鮮果穗產量高。對露菌病、莖腐病、病毒病及普通型與南方型�蚽f均具中抗,果皮薄,鮮食品質佳。PWH 81-2適合西部苗栗以南地區栽培,每公頃推荐株數47,200株,行株距85×25公分。施肥量:N:140-180公斤╱公頃,P2O5:60-90公斤╱公頃,K2O:60-90公斤。新品系 PWH 81-2 於2000年6月2日經農委會召開之作物新品種登記命名審查會通過,命名為「臺南22號」。 |
英文摘要 | Tainan No. 22 is a single cross hybrid of green white corn. It was coded as PWH 81-2 before registration. Its pedigree is TN 2661×PD 3732. The maternal line TN 2661 was bred from one green white corn population collected in Tainan district and has white semiflint kernel. It is characterized with moderate resistant to maize dwarf mosaic virus ( MDMV-B ), susceptible to downy mildew ( Peronosclerospora saccharl ), stalk rot ( Pythium aphanidermaum ) and rust disease ( Puccinia sorghi, P. polysora ) and yields grain 2,038 kg/ha. The paternal line PD 3732 was developed from another green white corn population obtained in Pingtung area and also has white semiflint kernel. It is possessed with characteristics of resistant to downy mildew and stalk rot modererate resistant to MDMV-B and both common rust and southern rust. Its grain yield per hectare is 2,186 kg. Since being selected out in spring crop, 1994. PWH 81-2 was recommended to participate in the 2-year islandwide regional yield trial, tests on effects of nitrogen rate and plant density, and phosphorus and potassium levels on plant height ear height and fresh ear yield, quality analysis and sensory evaluation for eating traits, reaction test to major corn diseaes. The data collected from the foremetioned tests indicated that PWH 81-2 is characterized with high-yielding with unstablity and moderate resistant to downy mildew, stalk rot, MDMV-B and both common and southern rust and with good eating quality. These revealed that PWH 81-2 is suitable for cultivation south from Maiolia to Kaohisung in the western part of the country and for fresh consumption. After being fully examined by the meeting of the new crop cultivar Registration Committee convened by the Council of Agriculture, Executive Yuan. PWH 81-2 was named as “Tainan No. 22” on June 2, 2000. The proper plant density for Tainan No. 22 is 47,200 plants/ ha. ( distance between rows is 85 cm, between hills within row is 25 cm ). The recommended amount of N.P.K. fertilizer per hectare is 140-180 kg, 60-90 kg and 60-90 kg. Respectively. |
