中文摘要 | 蕹菜為本省夏季主要葉菜類之一,但因品種問混雜,致使外觀整齊度較差,本場於民國78年,從北部竹葉種篩選出莖葉濃綠,葉片細窄且狹長,葉數多,刺瘤少,品質佳等性狀均一優良植株250株,作成一族群並以78002-1為代號,進行無性繁殖,混合栽培開放自然授粉、隔離採種與純化優良植株。並與各地方品種進行品系比較、肥料、栽植密度、採種與區域等一系列試驗,同時調查病蟲害之發生情形。民國84年6月9日正式命名為「桃園一號」供推廣栽培。 桃園一號植株特性,葉片為長披針形,葉色濃綠、葉柄短、節間較短、葉數多、莖部刺瘤少等。植株外觀形態屬直立性,整齊度可達95%。播種一次採收的產量為2,222±285 kg/10a,較各地區之竹葉種可增產20%:若播種後以宿根方式採收二次,其葉片仍保持狹長、葉數多與高產等特性。故可因減少種子費用,而降低生產成本。又經地方試作結果,適於本省北、中、南部等各地區栽培,採種在中、南部為宜。 |
英文摘要 | The new water convolvulus variety Taoyuan No.1 was developed by Taoyuan District Agricultural Improvement Station, selected from the northern local variety Chu- Yeh-Joong. After purification and a series of preliminary, advanced, fertilizer, density and regional yield trials combined with disease and insect measurement, the selected strain coded as 78002-1 was registered as Taoyuan No.1 and was released for commercial production in June 1995. The characteristics of the plant are summarized as follows. Taoyuan No.1 is a variety of leafy with erect plant type. The leaf is long lanceolate shape, dark green in color with slinder and narrow in shape, short petiole and internode. There are less spine on the stem. It performed high yield potential in per unit area. The yield of 2222±285 kg/10a was recorded from the first harvesting. The new variety gave 20% higher yield than the original local variety Chu-Yeh-Joong when planted in northern and other places such as central and southern parts of Taiwan. High yield and horticultural characteristics could also maintain by raising stump as ratoon culture after first harvesting. Taoyuan No.1 is suitable grown in areas from northern through southern parts of Taiwan. |
