为了阐明花生网斑病抗性的遗传规律,以抗病性存在明显差异的2个亲本组配的2个多世代群体为研究对象,应用分离群体分析方法(SEA)进行遗传模型分析。结果表明,花生网斑病的抗性遗传表现为E-1(MX2-ADI-AD)模型,即2对加性-显性-上位性主基因... 为了阐明花生网斑病抗性的遗传规律,以抗病性存在明显差异的2个亲本组配的2个多世代群体为研究对象,应用分离群体分析方法(SEA)进行遗传模型分析。结果表明,花生网斑病的抗性遗传表现为E-1(MX2-ADI-AD)模型,即2对加性-显性-上位性主基因+加性-显性多基因控制,以主基因遗传为主,与抗性相关的主基因遗传率在不同群体材料(W1701:YH×G99,W1702:G99×YH)中分别表现为80.09%和88.29%,基因的遗传效应以加性效应和显性效应为主。研究结果为花生网斑病抗性基因定位和抗性育种奠定了理论基础。 展开更多

Shanghua 511 is a high-yield, high-oil and web blotch-resistant big peanut variety bred by the Shangqiu Academy of Agriculture and Forestry Sciences through sexual hybridization (Yuhua 18♀×Shangyan 9658♂). In the wheat-peanut interplanting regional experiment conducted in Henan Province during 2012-2013, the average pod and seed yield of Shanghua 511 were 5906.19 and 4149.3 kg/hm2, respectively. In the wheat-peanut interplanting production experiment conducted in Henan Province in 2013, the average pod and seed yield of Shanghua 511 were 6036.45 and 4309.50 kg/hm2, respectively. In the kernels of Shanghua 511, the contents of crude fat, oleic acid and linoleic acid were 56.62%, 44.9% and 33.4% respectively, and the oleic/linoleic acid ratio was 1.34. This variety had high resistance to web blotch and medium resistance to leaf spot, viral diseases, root rot and collar rot. The 100-pod weight, 100-kernel weight, shelling percentage and growth period of Shanghua 511 were 270.6, 110.9 g, 70.6% and 120 d, respectively. Shanghua 511 passed the approval of Henan Provincial Crop Variety Approval Committee in August, 2015, and is suitable for spring sowing and wheat interplanting in the surrounding area of Henan Province and the area to the north of Huaihe River. 展开更多
