Examples of the orchard include pome fruits such as apple, pear, Japanese pear, Chinese quince and quince; stone fruits such as peach, plum, nectarine, Japanese apricot, cherry, apricot and prune; citrus such as Satsuma orange, orange, lemon, lime and grapefruit; tree nuts such as chestnut, walnut, hazelnut, almond nut, pistachio nut, cashew nut and macadamia nut; berries such as blueberry, cranberry, blackberry and raspberry; grape; persimmon; olive; and loquat. [0027] Examples of the non-cultivated land in the present invention include playground, vacant land, neighborhood of railroad, park, car park, neighborhood of road, dry riverbed, land under power-transmission lines, land for housing and site for factor. [0028] Crops cultivated in the farm crop field in the present invention are not limited as long as they belong to cultivars which are generally cultivated as crops, 8 S33213 These plant cultivars include plants, to which resistance to herbicides has been imparted by a classical breeding method or genetic recombination technology, the herbicides being protoporphyrinogen oxidase inhibitors such as flumioxazin; 4-hydroxyphenylpyruvate dioxygenase inhibitors such as isoxaflutole; acetolactate synthase inhibitors such as imazethapyr and thifensulfuron-methyl; acetyl CoA carboxylase inhibitors such as sethoxydim; 5-enolpyruvylshikimate-3 -phosphate synthase inhibitors suchas glyphosate; glutamine synthase inhibitors such as glufosinate; auxin type herbicides such as 2,4 -D and dicamba; and bromoxynil. [0029] Examples of the crop, to which resistance to herbicides has been imparted by a classical breeding method, include corn which is resistant to an imidazolinone type acetolactate synthase inhibiting herbicide such as imazethapyr, and which has already been sold under the trade name of Clearfield (registered trademark). Such a crop also includes STS soybean which is resistant to a sulfonylurea type acetolactate synthase inhibiting herbicide such as thifensulfuron-methyl. Similarly, examples of the plant, to which resistance to an acetyl CoA carboxylase inhibitor such as a trione oxime or aryloxyphenoxypropionic acid type herbicide has been imparted by a classical breeding method, include SR corn. Examples of the plant, to which resistance to herbicides 9 S33213 has been imparted by genetic recombination technology, include corn, soybean and cotton, each having resistance to glyphosate, and which have already been sold under the trade names of RoundupReady (registered trademark), Agrisure (registered trademark) GT, and Gly-Tol (registered trademark). Similarly, plants, to which resistance to herbicides has been imparted by genetic recombination technology, include corn, soybean and cotton, each having resistance to glufosinate, and they have already been sold under the trade name of LibertyLink (registered trademark). There are corn and soybean cultivars, which are resistant to both glyphosate and ALS inhibitors, and are sold under the trade name of Optimum (registered trademark) GAT (registered trademark). Similarly, there is soybean, to which resistance to an imidazolinone type acetolactate synthase inhibitorhas been imparted by genetic recombination technology, and which has been developed under the trade name of Cultivance. Similarly, there is cotton, to which resistance to bromoxynil has been imparted by genetic recombination technology, and which has already been sold under the trade name of BXN (registered trademark). Crops such as soybean having resistance to dicamba can be fabricated by introducing a dicamba-degrading enzyme such as dicamba monooxygenase isolated from Pseudomonas maltophilia into the plant (Behrens et al. 2007 Science 316: 1185-1188). Crops having resistance to both phenoxy acid type 10 S33213 herbicidez such as 2,4-D, MCPA, dichlorprop and mecoprop, and aryloxyphenoxypropionic acid type herbicides such as quizalof op, haloxyfop, fluazifop, diclofop, fenoxaprop, metamifop, cyhalof op and clodinafop can be fabricated by introducing a gene encoding an aryloxyalkanoate dioxygenase (Wright et al. 2010: Proceedings of National Academy of Science. 107(47): 20240-20245). [0030] By introducing a gene encoding a 4-hydroxyphenylpyruvate dioxygenase (hereinafter referred to as HPPD) inhibitor which exhibits resistance to HPPD inhibitor, and thus plants having resistance to the HPPD inhibitor can be fabricated (US2004/0058427). By introducing a gene capable of synthesizing homogentisic acid as a product of HPPD through another metabolic pathway, homogentisic acid is produced even in the presence of a HPPD inhibitor, and thus making it possible to fabricate plants which exhibits resistance to the HPPD inhibitor (WO 02/036787) . By introducing a gene capable of excessively expressing HPPD, HPPD is produced in the amount which does not exert an adverse influence on the growth of the plant even in the presence of a HPPD inhibitor, and thus making it possible to fabricate plants which exhibit resistance to the HPPD inhibitor (WO 96/38567). By introducing aforementioned gene capable of excessively expressing HPPD and also introducing a gene encoding a prephenate dehydrogenase so as to increase 11 S33213 the production amount of p-hydroxyphenylpyruvic acid as a substrate of HPPD, and thus making it possible to f abricate plants which exhibit resistance to the HPPD inhibitor (Rippert P et al. 2004 Engineering plant shikimate pathway for production of tocotrienol and improving herbicide resistance. Plant Physiol. 134: 92-100). [0031] Examples of the other method of imparting resistance to a herbicide include methods of introducing genes described in WO 98/20144, WO 2002/46387 and US2005/0246800. [0032] Aforementioned crops also include crops which made it possible to synthesize selective toxins known as the genus Bacillus, using genetic recombination technology. Examples of toxins expressed in these transgenic plants include insecticidal proteins derived from Bacillus cereus and Bacillus popilliae; 6-endotoxins derived from Bacillus thuringiensis, e.g. CrylAb, CrylAc, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1,Cry9C,Cry34ab and Cry35ab, and insecticidal proteins such as VIP1, VIP2, VIP3 and VIP3A; insecticidal toxins derived from nematodes; insecticidal toxins producedbyanimals, such as scorpion toxin, spider toxin, bee toxin and insect-specific neurotoxins; filamentous fungi toxins; plant lectins; agglutinin; protease inhibitor such as trypsin inhibitor, serine protease inhibitor, patatin, cystatin and 12 S33213 papain inhibitor; ribosome-inactivating proteins (RIP) such as ricin, corn-RIP, abrin, rufin, sapolin and priodin; steroid metabolic enzymes such as 3-hydroxysteroid oxidase, ecdysteroid-UDP-glucosyltransferase and cholesterol oxidase; ecdysone inhibitor; HMG-CoA reductase; ion channel inhibitors such as sodium channel inhibitor and calcium channel inhibitor; juvenile hormone esterase; diuretic hormone acceptors; stilbene synthetase; bibenzyl synthetase; chitinase; and glucanase. The toxins expressed in these transgenic plants include hybrid toxins, partially deficient toxins and modified toxins , which derive from 5-endotoxin proteins such as CrylAb, CrylAc, Cry1F, CrylFa2, Cry2Ab, Cry3A, Cry3Bbl, Cry9C, Cry34Ab and Cry35Ab, and insecticidal proteins such as VIP1, VIP2, VIP3 and VIP3A. The hybrid toxins are fabricated by a novel combination of the different domains of these proteins, using genetic recombination technology. The known partially deficient toxin is CrylAb, in which apart of amino acid sequence is deficient. In modified toxins, one or more amino acids of a natural toxin are replaced. Examples of these toxins and transgenic plants capable of synthesizing these toxins are described in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878, and WO 03/052073. The toxins contained in these transgenic plants impart resistance to insect pests of Coleoptera, insect pests of Diptera and insect pests of Lepidoptera to the plants. 13 S33213 [0033] There have already been known transgenic plants having one or more insecticidal pest-resistant genes and capable of producing one or more toxins, and some of them are commercially available. Examples of the transgenic plants include YieldGard (registered trademark) (acorn variety expressing CrylAb toxin) , YieldGard Rootworm (registered trademark) (a corn variety expressing Cry3Bbl toxin), YieldGard Plus (registered trademark) (a cornvariety expressing CrylAb and Cry3Bbl toxins) , Herculex I (registered trademark) (a corn variety expressing CrylFa2 toxin and phosphinothricin N-acetyltransferase (PAT) to impart resistance to glufosinate), NatureGard (registered trademark), AGRISURE (registered trademark) CB Advantage (Btll cornborer (CB) character) , andProtecta (registered trademark) There have already been known transgenic cottons having one or more insecticidal pest-resistant genes and capable of producing one or more toxins, and some of them are commercially available. Examples of the transgenic cottons include BollGard (registered trademark) (cotton cultivar expressing a CrylAc toxin), BollGard (registered trademark) II (cotton cultivar expressing CrylAc and Cry2Ab toxins), BollGard (registered trademark) III (cotton cultivar expressing CrylAc, Cry2Ab and VIP3A toxins) , VipCot (registered trademark) (cotton cultivar expressing a VIP3A and CrylAb toxins) and WideStrike (registered trademark) (cottoncultivarexpressing CrylAc andCrylFtoxins) 14 S33213 Examples of the plant used in the present invention include plants imparted with resistance to aphidas, such as soybean having aRag1 (Resistance AphidGenel) gene introduced thereinto. [00341 The above crops also include those imparted with a capacity of producing an anti-pathogenic substance having selective activity. As the anti-pathogenic substance, PRproteins (PRPs, EP-A-0 392 225) are known. These anti-pathogenic substances and transgenic plants producing thereof are described in EP-A- 0 392 225, WO 95/33818, and EP-A-0 353 191. Examples of the anti-pathogenic substance expressed by the transgenic plants include ion channel inhibitors such as a sodium channel inhibitor and calcium channel inhibitor (KP1, KP4 and KP6 toxins produced by viruses are known) ; stilbene synthases; bibenzyl synthases; chitinase; glucanase; PR proteins; and substances produced by microorganisms, such as peptide antibiotics, antibiotics having a heterocyclic ring and protein factors (called genes resistant to plant diseases and are described in WO 03/000906) involved in plant disease resistance. [0035] The above crops include those imparted with useful traits, such as reformed oil component and enhanced amino acid content, by means of a genetic recombination technique. The crops are exemplified by VISTIVE (registered trademark) (low linolenic soybean with reduced linolenic acid content) and high-lysine 15 S33213 (high-oil) corn (corn with increased lysine or oil content) [0036] The crops further include stacked varieties, which are fabricated by combining the above classical herbicidal traits orherbicide resistant genes, insecticidalpest resistant genes, anti-pathogenic substance-producing genes, reformed oil component and enhanced amino acid content. [0037] The above-mentioned crops include those imparted with tolerance to diseases, tolerance to dehydration stresses, traits to increase sugar content, and so on.
