Past, present and future criteria to breed crops for water-limited environments in West Africa     

M. Dingkuhn  B.B. Singh  B. Clerget  J. Chantereau  B. Sultan 《Agricultural Water Management》2006,80(1-3):241-261

Asia's Green Revolution of the 1960s and 1970s has largely bypassed West Africa, and “modern” (high-yielding, input responsive) germplasm for staple crops has found comparatively little adoption, except for systems that are have good access to markets and sufficient water resources. It is unlikely, however, that breeding objectives conserving traditional crop characteristics as found in extensive systems would have been more successful. The authors identify systems caught in the agricultural transition from subsistence to intensified, market-oriented production as the most important target for crop improvement, and provide examples of new breeding objectives for cowpea, sorghum and upland rice. In each of these cases, breeders, with the help of physiologists, have developed innovative plant-type concepts that combine improved yield potential and input responsiveness with specific traditional crop characteristics that remain essential during the agricultural transition. In the case of cowpea, dual-purpose varieties were developed that produce a good grain yield due to an erect plant habit, then produce new leaves enabling a second harvest of green foliage. For upland rice systems that are limited by labour (mainly needed to control weeds that abound due to shortened fallow periods), a weed competitive plant type was developed from Oryza sativa × Oryza glaberrima crosses. Lastly, sorghum breeders who had previously deselected photoperiod sensitivity are now re-inserting sensitivity into plants having “modern” architecture, in order to allow for flexible sowing dates while maintaining an agro-ecologically optimal time of flowering near the end of the wet season. The ecophysiological basis of these plant types, their place in current and future cropping systems, as well as the problem of under-funding for their realisation, are discussed.  相似文献   

普通豇豆应用核心种质的SSR指纹图谱构建及多样性分析   总被引：1，自引：0，他引：1  

公丹  王素华  程须珍  王丽侠 《作物杂志》2020,36(4):79-166

不同种质资源群体的多样性及遗传背景分析可为种质资源收集保存及创新利用提供有效信息。对不同来源的88份普通豇豆应用核心种质资源进行了14个SSR位点的指纹图谱构建及多样性分析,共检测到39个等位变异,每对引物检测到2~5个,平均为2.79。多态信息含量（PIC）变幅为0.25~0.72,平均为0.58。UPGMA聚类结果显示,除了3对种质外,39个等位变异可将其他材料有效区分,且在遗传相似系数为0.63时,88份种质可分为4个类群,地理来源相同的材料有聚在一起的趋势。  相似文献   

Preliminary evaluation of pineapple mixed-cropping systems for protecting reclaimed gulleys in the tropics: An experiment in Southeast Nigeria     

S. N. Asoegwu  J. C. Obiefuna 《Land Degradation \u0026amp; Development》1990,2(3):237-241

This paper reports on research into the effectiveness of pineapple monocropping or intercropping systems (with cowpeas or egusi-melon) for reestablishing vegetative cover to check soil erosion on a reclaimed gulley in the tropical rainforest of southeastern Nigeria. High-density pineapple planting, intercropped with egusi-melon, was found to promote rapid vegetative cover, checked soil loss, improved soil structural stability and produced a high crop yield. Soil loss was moderate in pineapple plots intercropped with cowpeas and least in pineapple plots intercropped with egusi-melon. Increasing pineapple density enhanced the field establishment of cowpea and egusi-melon respectively.  相似文献   

转基因抗虫作物中豇豆胰蛋白酶抑制剂（CpTI）酶联免疫检测方法的建立   总被引：4，自引：0，他引：4  

芮玉奎  王保民  李召虎  段留生  田晓莉  翟志席  何钟佩 《中国农业科学》2004,37(10):1575-1579

 从10个不同豇豆品种中筛选出抑制剂活性最高的901青皮豇豆，提取豇豆胰蛋白酶抑制剂。通过G-75凝胶过滤、亲和层析纯化了豇豆胰蛋白酶抑制剂（CpTI）并制备了其兔多克隆抗体。用所制备的抗体建立了酶联免疫检测方法并检测了转CpTI编码基因棉花、水稻中的CpTI含量，发现棉花不同器官CpTI的表达量不尽相同。  相似文献

Mixed cropping with ice plant alleviates the damage and the growth of cowpea under consecutive NaCl treatment and after the recovery from high salinity     

Pamwenafye I. Nanhapo  Koji Yamane 《Plant Production Science》2017,20(1):111-125

We investigated the alleviative effects of mixed cropping using ice plant, which is one of the salt-accumulating halophytes, on the damage and growth inhibition of cowpea, which is not tolerant to high salinity. Three cropping patterns (mono cropping of cowpea and ice plant and their combination) were tested. The plants were treated with 0, 100, 200 and 300 mM NaCl for 14 days (consecutive NaCl). The plants were also treated with NaCl for 3 days, followed by 2 weeks (short-term recovery) and 1 month (long-term recovery) recovery. Salinity levels for short-term recovery were similar to those of the consecutive experiment, while the concentration of long-term recovery was 250 mM. The alleviative effects of mixed cropping in the consecutive NaCl experiment were observed at 200 and 300 mM NaCl. Mixed cropping significantly reduced the Na content in the cowpea leaves at 200 and 300 mM NaCl compared with mono cropping. In addition, the Na content in the soil of mix-cropped cowpea at 200 and 300 mM NaCl was statistically lower than that of the mono cropping. Mixed cropping was effective to recover from high concentration of NaCl in the experiments of short- and long-term recovery. These results indicate that mixed cropping with a halophyte could be effective in mitigating the damage and growth inhibition of a glycophyte not only under salinity but also under recovery periods.  相似文献
