A STUDY ON THE INFLUENCES OF ENVIRONMENTAL FACTORS TO THE PURE LINE SELECTION FROM HYBRID POPULATION OF RICE-Part 1. The Response of Yielding Capacity Among Different Pure Line Groups Selected at Different Localities Taiwan Agricultural Research Institute
T.S. Miu; 繆進三.
[[abstract]]In this study, the following two hybrid combinations were used: (A) Chia-nung 242 × Baritol (B) Taichung 65 × Baritol in which, parent varieties “Chia-nung 242” and “Taichung 65” are the most popular rice varieties in Taiwan. “Baritol” is an upland rice variety cultivated in the aboriginal region of Taiwan. By the use of two crossing combinations mentioned above, it is expected that through the successional generation of selections in the breeding program, new rice varieties with disease and drought resistant characters might be developed. How environmental factors influence the chance of pure-line selection from the hybrid populations having the same parental combinations was also involved in the study. F2 individuals in each of the...

STUDIES ON YIELDING CAPACITY OF RICE VARIETIES CULTIVATED IN TAIWAN UNDER HIGH AND LOW TEMPERATURE Taiwan Agricultural Research Institute
T.S. Miu; W.C. Wang; J.H. Chang; 膠進三; 王文中; 張珍鉷.
[[abstract]]In order to measure influences of different temperature conditions on the yield-ing capacity of rice varieties in Taiwan, three localities at different sea levels, i. e. Taipei (15 m. above the sea level) Wu-lai (220 m., 1-2°C lower than in Taipei) and Chu-tsu-fu (660 m., 3-5°C lower than in Taipei) were selected as the site of the experiment. In the 1st crop period of 1959, 4 rice varieties (Japonica) were planted in pots with ten replications filled with the same soil and with the same amount of fertilizers to evaluate the effect of temperatures on fertilizer response and yielding capacity. The results of this experiment indicated that at Wu-lai where the temperature was lower gave a highest yield on the average, while at Taipei with a higher...

不同環境因子對稻雜交育種後代集團遺傳形質選擇之影響-第二報 各地區育成新品系羣產量變量分析 Taiwan Agricultural Research Institute
繆進三; 張魯智; 張正敏; T.S. Miu; L.C. Chang; C.M. Chang.
[[abstract]](一)以同親本雜交後代,在不同地區(臺北、臺中、嘉義、屏東)分離淘汰,逐漸固定,每地各選出12品系,4處綜合成48品系,作綜合性之區域適應試驗,研究各品系羣之區域適應性。 (二)在第一期作,臺北、臺中、嘉義三處試驗區,品系羣間差異未達顯著點;即表示當第一期作時,四處地方(臺北、臺中、嘉義、屏東)育成之新品系,在以上三處地方(臺北、臺中、嘉義)其羣與羣間(每羣包括12品系)產量差異均不顯著。但如撇開顯著性問題,希望初步概念,僅就其差異趨勢直敘,可見中南部育成品系,均有向臺北適應之可能。臺中育成品系,最適應於臺中本地之栽培利用;嘉義育成品系在嘉義亦有較佳之表現。惟臺北育成品系,在各處表現均不佳,雖差異未達顯著點,但此與第一期作因種子量少重複次數少(兩重複)亦有關係,惟有第一期作屏東試驗區,品系羣間谷粒生產力比較,差異顯著;其內容顯示屏東地方一期作栽培嘉義品系羣,結果較佳,甚至優於屏東本身育成之品系。至於臺中、臺北品系羣,第一期作在屏東種植,生育期短促,病蟲害叢生,空粒多,以致谷粒產量減少,表示對屏東環境不能適應。...

利用抗病品種抑制屏東地區水稻黃枯症之理論與實效 Taiwan Agricultural Research Institute
繆進三; T.S. Miu.
[[abstract]]溯民國四十九年第二期作,本省屏東地區,忽然發生一種稻作新病害,初起時葉尖變黃,稍後葉片黃褐,最後全蘗枯死,其影響產量原因,由於有效分蘗減少,株高降低,抽穗困難,一部份稻穗停滯在葉鞘內,谷粒部份不稔或全部不稔。屏東地區,四十九年被害之稻田總面積達13,000餘公頃,影響稻谷產量,最高者損失達70%,可謂來勢兇猛;但據當地農業者觀察記錄,先一年已有本病跡象,但面積不大,未為各方注意。迄49年迅速蔓延,始覺事態嚴重。筆者於本病初起時,即發現本病在品種間及雜交集團內單株上為害程度,差異甚大。衷心竊慰,私忖本問題可以用育種方法解決。乃呼籲利用抗病品種,抑制其蔓延。曾於民國50年起,先後於高雄臺灣新聞報三次專文報導,本病品種間抵抗力之差異,希望拋磚引玉,使當地農民對栽培之品種,能自行知所取捨。當時根據本人在發病地區舉行之稻品種抗病檢定,發現「嘉南二號」抗病性最強;而屏東縣內埔鄉農友亦利用過去高雄農改場地方示範保留之品種,選出抗病品種「高育十號」,產量與「嘉南二號」相近,但成熟期早五天,由於此品種在屏東地區逐漸不推自廣,目前已達二萬餘公頃,本病遂被抑制,斯誠不幸中之大幸。惟本病迄52年第二期作止,雖然為害面積已由最猖獗時期(民國49年)之13,000餘公頃,逐漸降至900餘公頃,但仍未全部絕跡,(事實上以上剩餘之900餘公頃病害面積,可能包括少部份真正「窒息病」病害面積在內,此部份是更新稻品種無作用,而非屬於黃枯症者。)其中關於黃枯症部份,尤需要繼續努力,予以一鼓撲減,因星星之火,可以燎原,值此病情漸趨緩和之際,允宜檢討過去績效,為未來繼續防範之參考;同時為本病與所謂「窒息病」作一明朗區別,以免混淆,想亦關心者所樂聞也。 From experiments on the response of...

放射能處理甘諸儲藏研究及處理後營養分之變遷 Taiwan Agricultural Research Institute
膠進三; 鍾桂堂; T.S. Miu; K.T. Tson.
[[abstract]]目前歐美各國,對于食物儲藏,如肉類、奶汁、蔬菜、果品等,均已試行應用放射能處理。至目前為止,其實驗結果,認為放射能處理,尚不能完全代替其他食物儲藏處理之方法。但其逐漸發展,在適當條件與專門目的之下,可用為現在通行儲藏方決之補助措施。如冷凍、加熱,化學藥品,脫水,抗生素之應用等儲藏處理方法,配合以較低劑量之適當放射能處理,當可逐漸達到經濟上應用之目的(3)。據 Connor, Jolinson, Metta 及 Tsien 等氏報告(2,4),渠等曾用 Gamma 線 3,000,000γ消毒牛肉、牛奶、麵粉及各種豆類蔬菜,以便保存。研究結果,放射能消毒之肉、乳含有之氮化物及其消化率、吸收率與生肉、生牛乳無大差異,或差異不甚顯著。氏等用感受放射線之牛肉與麵粉分三組飼養23星期年齡之雌鼠,每星期調查其體重增加之數量,結果表示對其生長發育並無影響。 A. H. Sparrow 與 E. Christensen 二氏(1)以馬鈴薯為研究材料,在美國Brookhaven研究所,經過數年之勸究,照射C60γ-線,其劑量為 1,250, 5,000, 20,000與80,000γ。處理後並予冷藏。迨8個月後觀察,認為5,O00γ及20,000γ兩處理情形較佳,其餘者均略呈軟化。至18個月後,5,000γ及20,000γ仍然較堅實,對照處理則已更形柔軟皺縮。至於前二處理食味品質,仍無大變化。但原作者未有化學分析報告,僅謂高劑量處理對維他命含量可能減少,蓋基于英國方面對于桔汁之分析報告如此。...
