马铃薯适应性强、产量高,块茎富含淀粉,其淀粉品质优于其他作物。马铃薯淀粉加工需要品种产量高、淀粉含量高,且在年际间表现稳定。以垦区主栽品种‘延薯4号’为对照,评价6个马铃薯品种的块茎产量、淀粉含量、淀粉产量及其稳定性,以期筛选出适用于当地马铃薯淀粉加工的品种。试验于2019~2021年在克山农场进行,采用随机区组设计,4次重复。块茎产量、淀粉含量、淀粉产量品种×年份互作效应显著,所以需要进行品种稳定性分析。‘北薯2号’淀粉含量21.77%,淀粉产量11 304 kg/hm2,均显著高于对照品种‘延薯4号’,且年际间表现稳定,表现出淀粉加工品种的潜力。‘东农321’淀粉含量14.82%,稳定性中等,块茎产量较高,为53 170 kg/hm2,稳定性好,由于块茎产量较高,所以淀粉产量较高且表现稳定,可作鲜食和淀粉加工兼用型品种试种。研究结果可为马铃薯淀粉加工企业品种选择提供依据。 相似文献

马铃薯新品系产量稳定性分析 总被引:1,自引:0,他引:1
本文利用Eberhart和Russell(1966)提出的方法,评价了1990年参加国家级东北片第四轮马铃薯品种区域试验中晚熟组6个点的3个品系,克863,春薯84—8和呼单81—213,以及对照品种克新2号的产量稳定性.克863和春薯84-8的块茎产量显著高于对照品种克新2号,而呼单81-213的产量和对照差异不显著.4个品种(系)的bi和1差异不显著,表现出显著差异,克863和克新2号的S和0差异显著,而春薯84-8和呼单81-213的S和0差异不显著.产量最高者克863产量不稳定,春薯84-8表现出平均稳定性。 相似文献

试验对华亚2号、华亚3号、华亚4号、华亚5号、Amine(荷兰)和Vesta(荷兰)6个亚麻品种在2018—2021年内5个关键农艺性状和4个产量性状的变化趋势以及相关性进行分析。结果表明,6个亚麻品种蒴果数和种子产量的变异系数较大,稳定性相对较弱,其余农艺性状均表现出较好的变异性。其中华亚2号、华亚5号、Amine和Vesta干茎制成率的变异系数均小于3%,变异幅度小,稳定性较强。6个亚麻品种的种子产量、纤维产量、原茎产量和全麻率的变化趋势不同:华亚2号、Amine和Vesta亚麻品种种子产量均呈上升趋势;华亚2号、华亚4号、华亚5号和Amine的原茎产量呈上升趋势,其余两种呈略下降趋势;华亚3号纤维产量略下降,其余品种整体呈上升趋势;6个亚麻品种的全麻率变化趋势稳定。相关性分析结果显示,株高、工艺长是影响亚麻原茎产量和纤维产量的最主要因素,与原茎产量和纤维产量均呈极显著正相关(p<0.01),株高和工艺长是影响亚麻产量的重要性状,提高亚麻品种的株高和工艺长是提高纤维产量和原茎产量的有效途径。上述研究为亚麻育种规划、开发高产改良品种提供理论基础。 相似文献

Genetic gains of cultivated peanut (Arachis hypogaea L.) have increased harvest index and disease tolerance, resulting in improved yield potential and broad-range adaptability of peanut cultivars to United States (U.S.) peanut production regions. Although this strategy has been successful, future yield increases may require peanut cultivars specifically adapted to environmental and management systems of a particular production region. Irrigation is one major management factor that varies across U.S. production regions and influences yield stability. Therefore, peanut germplasm selection for developing specifically adapted cultivars depends on knowledge of genotypic (G) pod yield responses to irrigation (M) across contrasting environmental (E) conditions (G × E × M interaction). The objectives of this 2-year study were to characterize germplasm by: (i) examining genotypic pod yield response to irrigation at locations in Florida and Texas; and (ii) estimating the genotypic pod yield performance and stability using genotype plus genotype-by-environment interaction (GGE) biplots. At the Florida location, genotypes New Mexico Valencia C (NMVC), COC 041, and Chico responded positively to increasing water application, whereas FloRun? ‘107?, C76 16, and FlavorRunner 458 responded negatively. Genotypes C76 16, ICGS 76, Chico, and ICGV 86015 had pod yields greater than the population mean. The genotype ICGS 76 had both high pod yields and stability. Pod yields of Chico were greater at the southwest locations, whereas ICGV 86015 had greater pod yields at the southeast locations. These results demonstrate a range in adaptability of distinct peanut genotypes that can be used in breeding programs for developing improved cultivars.Abbreviations: G × E: genotype-by-environment interaction; G × E × M: genotype-by-environment-by-management interaction; G × M: genotype-by-management interaction; NMVC: New Mexico Valencia C; TWRPET: total water received as a percentage of ETo 相似文献

Peanut kernels, untreated or soaked in salt solution, were roasted at 160°C for 30 min in a hot air oven or oil roasted at 147°C for 2 min and, stored at 27°C and 5°C up to 150 days. The heat treatments significantly decreased methionine, tryptophan and in vitro protein digestibility (IVPD) and, increased the soluble proteins and acid value of kernel oil. Storage of heated peanuts caused an increase in water-soluble proteins, IVPD, acid value and saponification value and a decrease in methionine, tryptophan and iodine value. The oil roasting was found to be more detrimental to nutritional quality and storage stability of peanuts as compared to dry roasting. The storage of heated peanuts at 5°C was found to be beneficial in lowering the undesirable nutritional changes in the peanut kernels. 相似文献
