山藥優良品系70W04在植物分類上近似於D. alata L.,而山藥臺農1號則具有典型田薯(D. alata L.)之特性,二者同屬晚熟型白肉山藥。由三個連續栽培年度及三個不同地點之試驗結果可知,70W04及山藥臺農1號在單株平均塊莖收量、田間成活率及塊莖公頃產量三方面之表現均甚佳且穩定,二者同具有31t/ha之生產能力,較中熟型白肉山藥品系70W03及早熟型紅肉之70R01為高。由不同海拔之試驗結果可知,較高海拔對中及晚熟型白肉山藥塊莖性狀及產量之影響極大,對70R01之影響則較小,70W04、70W03及山藥臺農1號在800m羅娜地區之產量分別只為10.9t/ha、10.1t/ha及10.4t/ha,而70R01仍有13.7t/ha之產量。70W04之生育期為8個月,但在6個月時其塊莖公頃產量即超過21t/ha,可依市場需要決定採收時期。利用塑膠穴管栽培時,70W04於8個月生長期之產量可達27.6t/ha,約為一般種植方式之84.4%,但採收極為方便,且塊莖較長,外觀平直光滑,不受傷損,穴管栽培方式極具參考利用價值。70W04塊莖皮薄肉厚,富含蛋白質(13.3%)與澱粉,另具礦物元素P、K、Ca、S、Mg及微量元素Fe、Cu及Zn等成分,此外,其肉質味美、粘度甚高、顏色潔白、且不易褐化,深具食用、加工用及保健價值。
Taxonomically, yam line 70W04 is suggested to be under Dioscorea alata L. although its identification has yet to be determined. It possesses similar botanical characteristics of yam cultivar Tainung No. 1, a typical Dioscorea alata L. Both have a growth duration of 8 to 9 months, and belong to the late maturity class of yam. Field studies were conducted to investigate the agronomic and yield performance of these two genotypes along with two other yam lines, 70W03 and 70R01. Experimental results obtained from three consecutive years of cultivation at Taichung area and one year at three different locations indicated that both 70W04 and Tainung No. 1 exhibited high and stable yield potential with average tuber yield over 31 t/ha. The two genotypes also had a much better performance in field survival rate and mean tuber yield per plant as compared to other entries. Cultivation at high altitude showed detrimental effect on the yield performance of yam. The yields of 70W04, 70W03, and Tainung No. 1 at Lona (altitude 800 m) were only 10.9 , 10.1, and 10.4t/ha, respectively, whereas 70R01 had a yield of 13.7t/ha. Harvest of line 70W04 at 6, 7, and 8 months after planting resulted in tuber yield of 21.1, 26.8, and 32.7t/ha, respectively. In other words, harvest could be done starting from the 6th month after planting to meet the market demand and the need of a certain rotation system. By cultivating line 70W04 in plastic pipes for 8 months, a yield of 27.6 t/ha was obtained. Although the yield was lower than that from normal cultivation, this method was still strongly recommended because the produced tubers were uniform in shape with high appearance quality. There was no mechanical damage to the tubers during the process of harvest. Yam line 70W04 possesses many superior characteristics such as thin skin, thick flesh with high quality texture, high viscosity, and high contents of protein (13.3%), starch, and many mineral elements. It is suitable for table use, processing and making foods for healthy purposes.
