The Breeding work of Octoploid Triticale since 1957 is summarized as follows:1. The use of crossable gene. The genetic analysis of the crossability between common wheat and rye has shown that s, ss, SA, SN and SQ belong to a multiple allelic series of a single locus. The degree of crossability of these genes can be arranged in such an order, namely, s > ss > SA > SN > SQ. According to the degree of dominance, the order should be reversed as: SQ > SN > ss > SA > s. These findings were properly used in the routine...

The Breeding work of Octoploid Triticale since 1957 is summarized as follows:1. The use of crossable gene. The genetic analysis of the crossability between common wheat and rye has shown that s, ss, SA, SN and SQ belong to a multiple allelic series of a single locus. The degree of crossability of these genes can be arranged in such an order, namely, s > ss > SA > SN > SQ. According to the degree of dominance, the order should be reversed as: SQ > SN > ss > SA > s. These findings were properly used in the routine work of crosses between wheat and rye.2. Chromosome doubling. Before treatment the wheat-rye hybrid seedlings should be slightly wounded on crown part by a sharp razor blade. Then the hybrid seedlings are exposed in 0.04-0.05% aqueous solution of colchicine for 4 days in room temperature not over 15℃. More than 90% of the treated seedlings could be recovered in greenhouse below 10℃. Among the recovered seedlings, about 40.8% of the sterile F1 hybrid plants would be turned to be partial fertile and various amount of seeds could be obtained from these successful plants. By this procedure, 4,700 primary Triticale strains have been created. In 1961, a new polyploidizing agent was discovered. The name of the agent is Fumiron, or Phenyl mercury-p-toluene sulfonanilide which is a fungicide and has comparable cfficiency in chromosome doubling as colchicine does.3. Fertility and seed plumpness. It was suggested that recombination of genes by hybridization and molding the segregation generations by heavy selection pressure could be the effective measures for the improvement of the fertility and seed plumpness of the octoploid Triticale strains. About two thousand of cross-combinations have been made with various parental stocks which were mostly selected from the primary Triticale strains, and in recent years, hybrid strains and elite plants in segregation generation were used in crosses more frequently than the primary types. The hybrid strains thus developed with normal fertility and acceptible seed plumpness were released to different localities with various natural conditions for yield tests.4. Regional tests. The data collected from regional tests have shown a tendency that the Triticale hybrid strains at present state might be successful in those regions where the yield of common wheat is usually very low and unstable due to severe natural conditions. For example, 10 Triticale strains were tested for yield performance with one rye and two common wheat varieties as checks in 1972-1973 growing season in Weining, a mountainous region of Kweiehow with altitude between 2-3 thousand meters. Eight out of ten Triticale strains have higher yields than both rye and wheat varieties. The best strain, Triticale No. 2 has a yield about 20% higher than that of rye, and 24% and 61% higher than the two varieties of common wheat Ahpo and No. 778 respectively. However, it, should not thus be concluded that the octoploid Tri-ticale is especially suitable for the marginal habitats of common wheat. It is only apparently seeming so at the present state of the Triticale strains which were developed from selection solely directed to the improvement of fertility and seed plumpness without much consideration for other characteristics of agricultural importance. Now, only the hardiness from rye and good seed quality from common wheat generally incoporated in the amphiploid have shown their favourable effect in the marginal regions of these two crops. This might be considered therefore that it is merely a preliminary stage of the Triticale program.

从1957年以来的八倍体小黑麦育种工作的主要结果总结如下: 1.可杂交基因的应用 小麦和黑麦之间的可杂交遗传分析表明s,s~S,s~A,s~N和s~Q是属于一个基因座的复等位基因。根据可杂交的程度,这些基因可以排成如下的次序,即s>s~S>s~A>s~N>s~Q。根据显性的程度,则其次序就要倒过来成为:s~Q>S~N>s~S>s~A>s。这个发现已被适当地应用于小麦与黑麦的日常杂交工作中。 2.染色体数加倍 小麦-黑麦杂种分蘖苗于处理前在基部用刀片切一浅伤口,而后浸在0.04—0.05%的秋水仙精溶液中4天,室温保持在15℃以下。在10℃以下的温室中,90%以上的处理苗能恢复生长。恢复苗中约有40.8%的F_1不育杂种植株能转变成部分可育的,并以这些成功株上将获得数目不等的种子。用这个方法,曾经制造了4,700个小黑麦原始品系。在1961年,发现了一个新的多倍体诱变剂。药品的名字是富民隆,或称对甲苯磺硫苯胺基苯汞,它是一个杀菌剂,加倍染色体数的效果和秋水仙精一样。 3.结实率和种子饱满度 通过杂交的基因重组和加重分离世代的选择压力是改进八倍体小黑麦的结实率和种子饱满度的有效方法。从小黑麦原始品系中选用各种亲本...

The damping-off disease is one of the most important diseases of pine seedlings in nurseries. By using some chemical fungicides we have effectively controlled this disease, but the soil pollution problem must still be considered. We have found out several ectomycorrhizac, such as Suillus grcvillei (K1.) Sing, and Boletus sp., that may not only promote the growth of pine seedlings, but also protect them from infection of damping-off disease.

从油松根部分离到的外生菌根真菌:牛肝菌之一种(Boletus sp.)和厚环粘盖牛肝菌(Suillus grevillei)除对油松(Pinus tabulaeformis)幼苗猝倒病有防治作用外,还能促进幼苗生长,其显著性水平P=0.01。引起油松幼苗猝倒病的病原菌主要是立枯丝核菌(Rhizoctonia solant)和尖孢镰刀菌(Fusarium oxysporum)。在盆栽接种试验中,用牛肝菌和厚环粘盖牛肝菌接种,油松幼苗发病率比对照降低21.0—36%;在田间接种试验中,松苗发病率比对照降低16.3—25.8%。用扫描电镜对接了种的油松幼苗进行观察,发现在油松营养根表面形成密集的菌丝套,而根尖则没有。用石腊切片观察到围绕在菌根皮层细胞周围的哈蒂氏网。采用500毫升的广口瓶,盛入草炭150克、细砂50克、玉米粉9克、红糖1克、麦芽汁(1.03波美)300毫升的配方,接种牛肝菌菌丝体,置30℃,10天左右产生山蘑菇子实体。

In regard to the control of soybean downy mildew, the present study showed that the occurrence of systemically-infected seedlings produced from oospore-encrusted seeds could be absolutely eliminated by treating seeds with 35% Apron at the rate of 35g a. i. per 100 kg seeds. Seed treatment with another fungicide, Aliette, at the rate of 240g a. i./100 kg seeds also gave an effective result where the systemically-infected seedlings reduced by more than 97%.The result of the experiment carried out in large...

In regard to the control of soybean downy mildew, the present study showed that the occurrence of systemically-infected seedlings produced from oospore-encrusted seeds could be absolutely eliminated by treating seeds with 35% Apron at the rate of 35g a. i. per 100 kg seeds. Seed treatment with another fungicide, Aliette, at the rate of 240g a. i./100 kg seeds also gave an effective result where the systemically-infected seedlings reduced by more than 97%.The result of the experiment carried out in large productive fields indicated that the spreading of soybean downy mildew was limited and the damage from the disease was obviously lessened in the growth season, attributed to the treatment of seeds with Aliette preventing the systemically-infected seedlings from being a primary source of the disease. By the harvest season the percentage of severe damage to the crop was cut down by 73% and that of oospore-encrusted seeds-by 90% respectively against the contol.It is necessary that the further evaluation of the method as one of potential measures for control of the disease should be conducted under varing conditions.

试验证明,采用35%甲霜安按种子重量0.1%拌种,可以完全免除由霜霉病粒引起的大豆霜霉病系统感染病苗的形成。防除效果达100%。采用80%抑霉灵按种子重量0.3%拌种,效果也在97%以上。 在大面积生产田的初步试验表明,采取抑霉灵拌种措施,由于基本消灭了由系统感染病苗所形成的初次发病中心,可以显著减轻整个生育期间大豆霜霉病的蔓延为害,最终发病严重率比不处理区降低73%,病粒率降低90%。认为这一措施应在不同生产条件下进一步试验验证。
