本研究以红皮品种扬麦17和白皮品种扬01-2为轮回亲本,Caiwx为Wx基因突变供体,通过传统回交方法和玉米花粉诱导单倍体技术分别创制了两种背景的Wx基因近等基因系,探讨了两种创制方法的异同;通过对两种背景近等基因系面粉的理化指标和面条品质的测定,研究了不同遗传背景和Wx基因组合对理化指标、面条品质的影响,为发展优质面条专用小麦新品种(系)及其产业化提供依据。初步研究结果如下:1.本研究以扬17为轮回亲本的BC9F2群体和扬17、扬01-2为轮回亲本的BC7F1单株诱导的双单倍体作为材料

Let G be a finite group. We say that a subgroup H of G is Uc-normal in G if G has a subnormal subgroup T such that TH = G and (H ∩ T)HG/HG is contained in the U
The Held group He discovered by Held [10] is a sporadic simple group of order 4030387200 = 210.3a.52.73.17. The group He has 11 conjugacy classes of maximal sub
q-Deformations of 3-Lie algebras and representations of q-3-Lie algebras are discussed.A q-3-Lie algebra (A,[,,]q,[,,]’q,Jq),where q ∈ F and q ≠ 0,is a vecto
We show that the matrix A(g), representing the element g = ((xy)2(xy2)2)m (m≥) of the modular group PSL(2,Z)=(x,y:x2=y3=1),where x:z →-1/z and y :z → -1/z, i
We introduce an algebraic K-theory for special groups, generalizing the mod 2 K-theory of fields due to Milnor, and apply it to give a positive answer to Lam’s
Some results about the representation of d.g. Seminear-rings are given. While not all d.g. Seminear-rings are faithful, it seems that there are conditions under
