3.3 The Formation and Development of <strong>the</strong> <strong>Diversification</strong> Patterns for WheatProductionWheat is <strong>the</strong> second most important gra<strong>in</strong> crop <strong>in</strong> Ch<strong>in</strong>a and <strong>the</strong> development andutilization of its varietal resources received much attention. Bima No.1 and o<strong>the</strong>r varietieswere bred <strong>in</strong> <strong>the</strong> 1950’s. These possess <strong>the</strong> characters of rust resistance and high yield<strong>in</strong>gability, so <strong>the</strong>y were well received by <strong>the</strong> farmers and were popularized over a large area.J<strong>in</strong>an No.2 and o<strong>the</strong>r varieties with <strong>the</strong> characteristics of disease resistance and high yield<strong>in</strong>gability were bred <strong>in</strong> <strong>the</strong> 1960’s. They were popularized over a large area <strong>in</strong> <strong>the</strong> w<strong>in</strong>ter wheatgrow<strong>in</strong>g area of nor<strong>the</strong>rn Ch<strong>in</strong>a. From <strong>the</strong> 1970’s, <strong>the</strong> orig<strong>in</strong>al varieties were graduallyreplaced by <strong>the</strong> improved dwarf varieties which possess <strong>the</strong> characteristics of rust resistanceand high yield<strong>in</strong>g ability. Each change of varieties made a great contribution to improvementof per unit yield of wheat. In recent years, cooperation <strong>in</strong> breed<strong>in</strong>g for resistance to diseasesamong <strong>the</strong> scientific research departments has been fur<strong>the</strong>r streng<strong>the</strong>ned and a number of rustresistant and high yield varieties of wheat have been bred and are under demonstration forextension on a large scale.In addition, Ch<strong>in</strong>a has also made a great breakthrough <strong>in</strong> new breed<strong>in</strong>g methods and<strong>in</strong>creased knowledge of <strong>the</strong> wheat crop, such as <strong>the</strong> classification of wheat, analysis of wheatvarieties and <strong>the</strong>ir pedigrees, <strong>the</strong> allo-octoploid triticale bred by hybridization between wheatand rye through chromosome doubl<strong>in</strong>g, and <strong>the</strong> new wheat varieties of Xiaoyan No. 4, No. 6and No. 967 bred by hybridization between wheat and quackgrass (Elytrigia repens). Thesehave made important contributions to <strong>the</strong> development of wheat <strong>in</strong> Ch<strong>in</strong>a.These new advances <strong>in</strong> wheat breed<strong>in</strong>g have helped Ch<strong>in</strong>ese farmers make significantadvances <strong>in</strong> crop diversification. In view of <strong>the</strong> plant<strong>in</strong>g systems now be<strong>in</strong>g adopted <strong>in</strong> <strong>the</strong>field, <strong>the</strong> multiple cropp<strong>in</strong>g patterns now make it possible for three crops to be grown everytwo years or two crops per year with a comb<strong>in</strong>ation of wheat-maize or cotton-maize whichhas become popular among farmers <strong>in</strong> nor<strong>the</strong>rn Ch<strong>in</strong>a for some time now. Ano<strong>the</strong>r successstory <strong>in</strong> crop diversification <strong>in</strong> recent years is <strong>the</strong> popular plant<strong>in</strong>g pattern of autumnvegetables (radish and Ch<strong>in</strong>ese cabbage) <strong>in</strong>tercropped with spr<strong>in</strong>g wheat <strong>in</strong> <strong>the</strong> north part ofNor<strong>the</strong>ast Ch<strong>in</strong>a where <strong>the</strong> per mu <strong>in</strong>come <strong>in</strong>creased by 200-250 yuan RMB, mak<strong>in</strong>g thiscropp<strong>in</strong>g pattern well received by <strong>the</strong> farmers.3.4 The Formation and Development of <strong>the</strong> <strong>Diversification</strong> Strategy us<strong>in</strong>g Maizeand o<strong>the</strong>r <strong>Crop</strong>sMaize is a major gra<strong>in</strong> crop <strong>in</strong> Ch<strong>in</strong>a and its diversification changes cont<strong>in</strong>uouslyfollow<strong>in</strong>g breakthroughs <strong>in</strong> <strong>the</strong> cross breed<strong>in</strong>g of maize. In <strong>the</strong> 1950’s, <strong>in</strong>ter-specific hybridswere ma<strong>in</strong>ly used <strong>in</strong> maize production <strong>in</strong> Ch<strong>in</strong>a. Early <strong>in</strong> <strong>the</strong> 1960’s, <strong>in</strong> addition to <strong>the</strong>utilization of <strong>in</strong>ter-specific hybrids, <strong>the</strong>se were comb<strong>in</strong>ed with double hybrids, three-waycross hybrids, top cross hybrids, and <strong>the</strong> advantage of heterosis was used comprehensively <strong>in</strong>maize production. In recent years new progress has been achieved <strong>in</strong> <strong>the</strong> selection andbreed<strong>in</strong>g of special purpose hybrid maize with high oil content, high prote<strong>in</strong> content, andhigh lys<strong>in</strong>e content as well as sweet maize and glut<strong>in</strong>ous maize. These hybrids have not onlyplayed an important role <strong>in</strong> <strong>in</strong>creas<strong>in</strong>g <strong>the</strong> yield of maize, but also contributed to <strong>the</strong>development of diversification programmes us<strong>in</strong>g maize varieties.Significant social and economic efficiency has been obta<strong>in</strong>ed <strong>in</strong> <strong>the</strong> selection andpopularization of new varieties of o<strong>the</strong>r crops, for <strong>in</strong>stance, <strong>the</strong> new comb<strong>in</strong>ation of Q<strong>in</strong>you27

CROP DIVERSIFICATION AS A STRATEGY FOR MAXIMIZING FOODPRODUCTION4.1 Security of Food and NutritionCh<strong>in</strong>a is a country with <strong>the</strong> highest population <strong>in</strong> <strong>the</strong> world. The Ch<strong>in</strong>ese governmentalways attaches importance to gra<strong>in</strong> production and takes gra<strong>in</strong> production as <strong>the</strong> basis ofnational food security and social stability. In <strong>the</strong> past 20 years or more, s<strong>in</strong>ce <strong>the</strong>implementation of <strong>the</strong> policy of reform and open<strong>in</strong>g to <strong>the</strong> outside world, <strong>the</strong> total amount ofgra<strong>in</strong> required for consumption has been effectively resolved <strong>in</strong> Ch<strong>in</strong>a. Ch<strong>in</strong>a’s gra<strong>in</strong> yieldper capita has reached about 400kg. Along with <strong>the</strong> development of <strong>the</strong> economy, <strong>the</strong> urbanand rural residents became more sophisticated <strong>in</strong> <strong>the</strong>ir demands based on specific varieties,quality and nutritive value of foods. In recent years, <strong>the</strong> type of crops grown has beenregulated progressively, with a bias towards <strong>the</strong> reputed, special, high quality, new and rareagricultural products which have been developed rapidly.4.2 Alleviat<strong>in</strong>g Poverty and Increas<strong>in</strong>g Income and EmploymentThe Ch<strong>in</strong>ese government always attaches importance to <strong>the</strong> development andproduction of gra<strong>in</strong>, <strong>in</strong>creas<strong>in</strong>g agricultural production, and solv<strong>in</strong>g <strong>the</strong> problem of selfsufficiency<strong>in</strong> food and cloth<strong>in</strong>g. In general, <strong>the</strong> problem of gra<strong>in</strong> security has been largelyresolved. However, ow<strong>in</strong>g to <strong>the</strong> unequal development between areas as well as <strong>the</strong> harshnatural environment <strong>in</strong> certa<strong>in</strong> <strong>region</strong>s, and poor l<strong>in</strong>ks <strong>in</strong> <strong>the</strong> distribution cha<strong>in</strong> with poorlyequipped transportation systems, <strong>the</strong>re are still about 42 million people who have not enoughto eat and wear even as recently as 1998.To solve <strong>the</strong>se problems, <strong>the</strong> government is try<strong>in</strong>g hard to improve <strong>the</strong> conditions ofagricultural production, quicken <strong>the</strong> economic development <strong>in</strong> poverty-stricken areas andguarantee gra<strong>in</strong> security for <strong>the</strong> poor people <strong>in</strong> rural areas on <strong>the</strong> basis of <strong>the</strong> policy ofstabiliz<strong>in</strong>g <strong>the</strong> rural areas and <strong>in</strong>creas<strong>in</strong>g agricultural <strong>in</strong>puts. Meanwhile, attention is alsostressed on <strong>the</strong> protection and development of crop resources, guid<strong>in</strong>g and encourag<strong>in</strong>gfarmers to adopt a market-oriented cropp<strong>in</strong>g structure, enlarg<strong>in</strong>g <strong>the</strong> scope of employmentfor farmers and enhanc<strong>in</strong>g <strong>the</strong>ir <strong>in</strong>come. In 1998, <strong>the</strong> poverty-alleviat<strong>in</strong>g fund <strong>in</strong>vested by <strong>the</strong>government exceeded 18.3 billion yuan RMB. This <strong>in</strong>vestment was used <strong>in</strong> plant<strong>in</strong>g andrais<strong>in</strong>g <strong>the</strong> production of poverty-stricken villages and families through a micro-creditscheme, which <strong>in</strong>deed promoted <strong>the</strong> economic development of poverty-stricken areas andhelped <strong>in</strong> solv<strong>in</strong>g <strong>the</strong> problem of provid<strong>in</strong>g sufficient food and warm cloth<strong>in</strong>g.4.3 Rational Utilization of Land, Water and o<strong>the</strong>r ResourcesProtect<strong>in</strong>g arable land, sav<strong>in</strong>g water and develop<strong>in</strong>g and us<strong>in</strong>g natural resources of<strong>the</strong> environment rationally is <strong>the</strong> base for ensur<strong>in</strong>g national gra<strong>in</strong> security, and achiev<strong>in</strong>gsusta<strong>in</strong>able development of agriculture as well as preserv<strong>in</strong>g <strong>the</strong> national wealth of crops andsafeguard<strong>in</strong>g <strong>the</strong> ecological balance. The Ch<strong>in</strong>ese government always provides specialprotection to arable land. For <strong>in</strong>stance, <strong>the</strong> basic farmland protect<strong>in</strong>g system, which has been28
