1.In order to produce a new disease-resistant and high-yielding variety of kenaf adaptedto the cultivating conditions of North China,the authors carried out several crossesbetween the varieties of early maturing northern type and those of the disease resistantsouthern type since 1955.Two superior strains,4-83 and 176-10,were selected from F_5of Madres (♀) ×Huanung No.1 and F_6 of Sullen 21(♀)×Madres.Both strains were ap-peared to be resistant of anthracnose of kenaf,caused by colletotrichum polacci,and with highfiber yield.The time of full blossom for these two strains in Peking district were in the middlepart of August.and at the end of July respectively,and both strains can be adapted to thelocal conditions for regular growth.2.From crosses between kenaf varieties,the resulting generations of F_1 and F_2 showedhybrid vigour in plant size.By means of directed selection,the desirable progenies maintainedtheir plant height,superior to the parents.3.The F_1 plants which derived from the crosses between the varieties of disease-resistanttype and those of susceptible type showed susceptibility to anthracnose.In F_2 and succeedinggenerations,both healthy and susceptible plants were segregated in a rate varied with strains.According to observation,it was found that the phenomenon of disease escape still occurredamong strains and among individuals within strains.Hence it was recognized that the testsfor disease resistance of the desirable strains must be conducted for 3-4 years.4.The selection of parental plants showed a great effect on the variation of charactersin the offspring,especially on the time of maturity.Under the natural conditions of Pekingdistrict,when the selected parents were both able to flower,the flowering plants in F_2 werefound to be in a greater percentage and began to bloom in an earlier stage.While in thecondition of either one of the selected parents was unable to flower,a lower percentage offlowering plants appeared in F_2 and the time of beginning to flower was delayed.If bothselected parents were in a state of very late maturing or even unable to flower,then,very few or not a single plant in F_2 was able to flower.Same tendency was observed in F_3and in the descending generations.In order to obtain a good proportion of flowering plants,the number of seeds sowing in various generations should be based upon the time of maturityof their parents.

Varietal reactions of rice to the bacterial leaf blight (Xanthomonas oryzas) were tested during 1957-1958 by means of artificial inoculations.Among 1209 varieties tested by succes-sive inoclations,none of them was found to be immune to the disease.But 23% of thevarieties tested was moderately resistant,2.15% was highly resistant.In general,varietiesof the glutinous type are more resistant than the non-glutinous type,and late matured varie-ties are more resistant than those matured earlier.Leaves of the susceptible varieties areusually characterized by having higher contents of certain free amino acids such as asparticacid and glutamic acid,and lower contents of polyphenols and reducing sugars.In somevarieties analyzed,however,the difference is not significant.Furthermore,it has been foundthat differences in the above mentioned components between different varieties are usuallyless significant than those induced in the same variety by varying the cultural Conditions,suchas the levels of nitrogen fertilizers to be reported in the following paper.Consequently,other physiological characteristics of varieties should be considered in explaining the mecha-nism of varietal resistance to the disease.

水稻不同品种对白叶枯病的抗病性不同。用人工接种的方法测定1209个品种,未发现有完全不发生白叶枯病的品种,但是发病较轻可列为抗病的,约占23%左右。高度抗病的品种26个,占2.15%。(禾山)稻和粳稻品种都有发病很重的,但是,粳稻抗病品种比(禾山)稻多。晚稻此早稻和中稻多。抗病品种叶片的有机物成分和含量与感病品种不同,抗病品种的多元酚和糖的含量高于感病的品种,游离氨基酸中的谷氨酸和门参氨酸的含量低于感病的品种。

This paper deals with the phenology and control of the cotton bollworm,Heliothis armigera,in the lake region of Hunan Province.The pest breeds four complete generations each year,with a partial incomplete fifth one.Diapausing pupae appear in the third generation in a few cases; and the majority of the pupae of the fourth generation go into diapause in the hibernating quarters under the ground.The rate of development is influenced by the local microclimatic factors.The adults usually mate after the midnight and...

This paper deals with the phenology and control of the cotton bollworm,Heliothis armigera,in the lake region of Hunan Province.The pest breeds four complete generations each year,with a partial incomplete fifth one.Diapausing pupae appear in the third generation in a few cases; and the majority of the pupae of the fourth generation go into diapause in the hibernating quarters under the ground.The rate of development is influenced by the local microclimatic factors.The adults usually mate after the midnight and the unfertilized,unhatchable eggs laid may amount to about 30% of the total.It was noted that corns were more heavily infested than cottons and the late maturing varieties of the crops more heavily infested than the early maturing ones.For chemical control a mixture of Oxydisulfoton and DDVP was found to be effective.

棉铃虫在湖南滨湖地区每年发生四代,少数不完整的五代。第三代出现少数滞育蛹,第四代蛹绝大多数滞育越冬,极少数可在当年羽化,幼虫越冬全部死亡。10月上、中旬幼虫下降至3—10厘米的土层中化蛹越冬,蛹的不同发育程度、色泽变化及各虫态历期均与温度变化有关。成虫交配一般在下半夜,雌蛾羽化后1—2天开始产卵。未受精卵约占总产卵数的34%。 玉米受害重于棉花,晚熟品种重于早熟品种。 保棉丰加敌敌畏的混合液,防治棉铃虫能起到很好的效果,并能兼治斜纹夜蛾和红蜘蛛。
