‘Chiquita’(譯名:奇奇蒂塔,橄欖小姑娘樹)是一種新的橄欖(Oela Eulaa. L.)品種,是在西班牙C.Rordba的雜交育種中獲得的。“Chiquitita”來源于1991年在“Picual(皮瓜兒)”和“Arbequina(阿爾貝吉納)”之間進行的雜交,這兩個品種的生產力和含油量都來自不同的地理來源:西班牙東北部加泰羅尼亞的“Arbequina”和南部安達盧西亞的“Picual”。西班牙(拉洛,1995)。在柯爾多瓦進行的農藝評價的結果允許最終選擇“Chiquitita”作為具有早生、高含油量和產量效率的新橄欖品種。它的低活力和緊湊和哭泣的生長習性使得它特別適合于高密度籬笆果園。“Chiquitita”是由科爾多瓦大學和農業和漁業研究訓練研究所(IFAPA)合作育種項目開發的第一個橄欖品種。

‘Chiquitita’ is a new olive (Olea europaea L.) cultivar obtained in a crossbreeding program in Córdoba, Spain. ‘Chiquitita’ was derived from a cross carried out in 1991 between ‘Picual’ and ‘Arbequina’, two cultivars with high productivity and oil content from different geographical origins: ‘Arbequina’ from Catalonia in the northeast of Spain and ‘Picual’ from Andalusia in the south of Spain (Rallo, 1995). The results of the agronomical evaluation carried out in Córdoba allow the final selection of ‘Chiquitita’ as a new olive cultivar with early bearing, high oil content, and yield efficiency. Its low vigor and compact and weeping growth habit make it particularly adapted to high-density hedgerow orchards. ‘Chiquitita’ is the first olive cultivar developed by the cooperative breeding program carried out by the University of Córdoba and the Institute of Agricultural and Fishery Research and Training (IFAPA)

Origin

起源
“Chiquitita”(育種記錄中的后代UC-I 8-7)的原始幼苗來源于1991年進行的“Picual”(雌性)和“Arbequina”(雄性)雜交。在1994年的田間試驗中,在C.Rordba的IFAPA Caloto ALAMDA DEBOBISPO的試驗場中進行了幼苗的種植。1996獲得第一茬,連續三個收獲季節進行苗木鑒定。“Chiquitita”的原苗主要根據其早熟(幼齡期短)和高含油量來選擇,還表現出緊湊和哭泣的生長習性(Len等人,2004)。選擇15個基因型,包括“Chiquitita”和以前引用的3個生殖器作為對照,于2000年春季通過半硬木莖扦插繁殖,并于2001年7月在位于科爾多瓦的阿拉米達中部奧比斯波的IFAPA實驗農場進行了比較試驗。一個隨機塊設計與16個重復和一棵樹每個基本圖使用。對基因型的評價證實了先前在苗期記錄的結果,并允許最終選擇“Chiquitita”作為新的橄欖品種。在高密度灌木籬果園中的一個新的比較田間試驗已經在2007種植。目前正在西班牙的多個地點進行更多的對比試驗。

   

The original seedling of ‘Chiquitita’ (progeny UC-I 8-7 in the breeding records) was derived from a cross between ‘Picual’ (female) and ‘Arbequina’ (male) carried out in 1991. The seedling was planted in the field in 1994 at the experimental farm of IFAPA Centro Alameda del Obispo of Córdoba. The first crop was obtained in 1996 and seedling evaluation was carried out for three consecutive harvest seasons. The original seedling of ‘Chiquitita’ was selected mainly on the basis of their early crop (short juvenile period) and high oil content, showing also compact and weeping growth habit (León et al., 2004). Fifteen selected genotypes, including ‘Chiquitita’, and the three previously cited genitors used as controls were propagated by semihardwood stem cuttings in Spring 2000 and planted in a comparative trial at the experimental farm of IFAPA Centro Alameda del Obispo of Córdoba in July 2001. A randomized block design with 16 replications and one tree per elementary plot were used. The evaluation of the genotypes confirmed the previous results recorded at the seedling stage and allowed the final selection of ‘Chiquitita’ as a new olive cultivar. A new comparative field trial with ‘Chiquitita’ in high-density hedgerow orchards has been already planted in 2007. More comparative trials are currently planned in several locations in Spain.

Description

描述
形態學描述是根據Balrango等人進行的。(2000)利用樹、葉、果、內果皮共25個性狀。利用10個微衛星位點,利用分子標記進行品種鑒定,這些微衛星位點先前用于育種計劃中的親子鑒定(Daz等人,出版社)。農學描述考慮了“Chiquitita”在原始育苗場進行的農學評價結果和在科爾多瓦阿拉米達中部奧比斯波試驗農場建立的比較田間試驗的結果。由于高密度籬笆果園似乎是該新品種的主要直接應用,因此將“Chiquitita”的農藝結果與目前用于該新果園系統的標準品種“Arbequina”進行了比較。


Morphological description was carried out according to Barranco et al. (2000) by using a total of 25 characters of the tree, leaf, fruit, and endocarp. Cultivar identification by molecular markers was performed with 10 microsatellite loci previously used for paternity testing in the breeding program (Díaz et al., in press). Agronomical description takes into account the results of the agronomical evaluation of ‘Chiquitita’ carried out in the original seedling field and the comparative field trial established both at the experimental farm of IFAPA Centro Alameda del Obispo of Córdoba. Because high-density hedgerow orchards seem to be the main direct application of this new cultivar, agronomical results of ‘Chiquitita’ are compared with those of ‘Arbequina’, the standard variety currently used for this new orchard system.

     新橄欖品種選育適合高密度配制果園。由科爾多瓦大學和安達魯茲農業研究所(IFAPA)的研究人員在1991年開始執行的橄欖育種計劃中獲得。它起源于“Picual”(雌性親本)和“Arbequina”(雄性親本)之間的雜交,這兩個品種在西班牙橄欖園中更廣泛地傳播。其中樹木的數量達到907橄欖樹/公頃。由于其活力很低,可以采用4×12的種植空間

     該品種在歐盟、智利、阿根廷、墨西哥、美國(命名為“Chiquitita”)、南非、澳大利亞、突尼斯、摩洛哥和土耳其受到保護。
