摘  要：
对133个小麦品种间杂交组合的观察结果指出,凡有免疫品种为亲本的组合,其 F_1抗病性表现显性的机率都很高,而其机率的高低又与另一亲本抗病性的强弱呈正相关。对24对正反交组合的 F_1代,8对的 F_2代和2对的 F_3代作比较观察的结果表明用免疫品种作父本与母本,对后代抗病性的表现和分离并无不同影响。根据田间调查结果,看出杂种后代中底部叶片轻微发病的植株其抗病性稳定程度和遗传力低于“全株免疫株”;用底部叶片发病,中上部叶片表现免疫的品种作抗病亲本,F_1代的中下部叶片发病比较普遍;而用全株免疫的品种作抗病亲本,F_1代一般没有发病现象。试验结果证明 F_1代和 F_2代中的“少茎病株”(同一植株中多数分蘖免疫,个别或少数分蘖感病),其后代(F_2和 F_3)分离出的免疫株率与全株免疫株差别不明显。感病分蘖与同株免疫分蘖的后代在抗病性的分离上也无显著差别。石特14×胜利组合 F_2免疫株的后代(F_3)中有15.8%的株系全部植株免疫;“0;”型和“1”型 F_3植株分离出的免疫株率各达到80.3%和55.5%,但汉有出现免疫的株系。

摘  要：
The inheritance of mature plant resistance to race CY-2 of Puccinia glumarum Erikss.et Henn.was studied in 133 sets of intervarietal crosses of winter wheat during 1955 to 1958.When immune varieties were used as one of the parents,resistance in the F_1 generation inmost of the crosses was shown to be dominant.The dominance of the resistance of F_1 hybridwas found to be not only conditioned by the immune parent but also more or less influencedby the degree of resistance of the other parent,being less with susceptible varieties thanwith resistant ones.With the resistant × resistant and resistant × susceptible crosses,therewas also a small portion in which the resistance of F_1 hybrid was shown to be dominant.Studies were made on F_1 plants of 24 pairs of crosses,F_2 plants of 8 pairs of crosses andF_3 plants of 2 pairs of crosses,for any reciprocal differences in the inheritance of resistance,each pair involving an immune and a susceptible parent.No difference was observed whe-ther the immune variety was used as maternal or as paternal parent.Analysis based on careful field observations indicated that the stability and the heritabilityof resistance of“partial immune”hybrid plants (only the middle and upper leaves being im-mune,while the lower leaves showing a susceptible or moderate resistant reaction) appearedto be lower than that of the“whole plant immune”ones (all leaves of the plant showing anuniform immune reaction).When varieties with“partial immune”reaction were used as theresistant parents,plants with infected middle and lower leaves were relatively common in theF_1 population.When a“whole plant immune”variety was used all the F_1 population wasfound to be unaffected.The importance of choosing the“whole plant immune”variety asresistant parent and selecting the“whole plant immune”hybrid plant in breeding rust resistantvarieties was emphasized.
