The hybrid Indica rice breeding in China has scored great achieve-ments,but the hybrid Japonica rice breeding developed slowly,due to laekof resources of the restorer.Since 1971,we started the hybrid Japonicarice breeding work.The results are briefly stated as follows:1.The Japonica type restorer C57,which possesses high combiningability and vigorous heterosis,is one of the wide-spectrumed restorersat present.2.(?).reeding restorer by means of triple crossing between Japonica andIndica is a good method which provides us with more probability of uti-lizing Indica nucleus so as to enrich its genetic potentiality.Using the“bridge method”could pave the way for utilizing heterosis between In-dica and Japonica and its excellent characters.3.The restorer C57 could improve plant type,leaf type,and couldincrease the“source”and“sink”of high yield for hybrid rice.

1.粳恢 C57具有较高配合力,杂种一代具有较强优势,花粉量大,有利于提高异交结实率,是当前较好的广谱恢复系。2.籼粳杂交复交与配子利用的“架桥”制恢方法,在杂种一代提供利用部分籼核的机率,丰富了遗传基础,为间接利用籼粳杂种优势及其优良性状开辟了途径。3.粳恢 C57对杂种一代的株型、叶型、高产的“”和“源”以及适应性等方面具有良好的改进和增强作用。

Cold injury which influence riee production in different rice growing countries oc- curs at various growth stages.The degree of cold injury depends on the air or water temperature,the cropping pattern,the growth stage of the rice and other factors.It is generally aeeepted that cold tolerance of rice at one stage is different from another stage.However,Okabe and Toriyama reported that varieties seem to respond simi- larly to cold temperature at different growth stages.Some varieties have been found to be tolerant...

Cold injury which influence riee production in different rice growing countries oc- curs at various growth stages.The degree of cold injury depends on the air or water temperature,the cropping pattern,the growth stage of the rice and other factors.It is generally aeeepted that cold tolerance of rice at one stage is different from another stage.However,Okabe and Toriyama reported that varieties seem to respond simi- larly to cold temperature at different growth stages.Some varieties have been found to be tolerant at different growth stages. The purpose of this experiment is to find whether cold tolerance scores at different growth stages of different kinds of riee are correlated or not.

从国际水稻研究所种质取得50个水稻品种,其中包括粳型品种12个,釉稻18个,爪哇型品种10个,釉×粳杂种3个,以及野生稻7个。在芽期、苗期、移栽期、孕穗期、开花期,进行了耐冷性的测定。结果指出,在不同的水稻类型中,其耐冷性的次序为:粳稻>爪哇型>秈稻>野生稻。从本实验所采用的有限量的品种来看,在苗期粳型品种的耐冷性比其它类型好;在开花期某些爪哇型品种比粳型品种好;在芽期和苗期之间,以及在芽期和开花期之间,其耐冷性有明显的正相关。在其它时期之间未找到这种相关性。这指出,在特殊地区的低温发生时期的一定生育阶段中,进行筛选是必要的。

Generally, the hatchability for practical use of the silkworm eggs after cold storage and acid treatment is not satisfactory, when the chilling period is less than 30 days, In order to increase the hatchability of silkworm eggs. Am experiment involving four factors: (A) duration of cold storage. (B) degree of high temperature exposed after the cold storage. (C) time exposed to high temperature and (D) duration of acid treatment was carried out to investigate their effect on the hatchability of silkworm eggs in 4 perent strains: Zhejiang Agricultural University No. 1 (ZAU No. 1), Dong34 Sul2 and Dong Fei.Results obtained were as follows:1. After oviposition, the eggs of 4 races were kept in cold storage after having been under protection at 24℃ for 50-60 hours. For those races that were kept in cold storage for less than 30 days, (A), (B), and (D) had more effect than (C), There was interaction among 4 factors. These findings suggest that in practice selection for the integrated factor combination should be emphasized. 2. There were significant differences among races as to the range of the factors used so arrive at a satisfactory hatchability for practical use, There was broader range of these factors to be eelected for Dong 34 and Su 12. The range was narrower for ZAU No.1, and as for Dong Fei, no satisfactory factor combination had yet been found from the range of the 4 factors set for the present experiment.3. Results showed that for the current summer and autnmn races ZAU No.1, Dong 34 and Su 12, with the normal treatment, cold storage of 20 days would be sufficient to bring about a hatchability for parctical use of more than 90%. The effect of time of acid treatment on ZAU No. 1 was especially marked, and in case of short time cold stroage, appropriately prolong the duration of acid treatment would be worthy of consideration.

为了提高30天以内的短期冷藏浸酸种的实用孵化率,对冷藏天数(A)、出后接触高温度数(B)、接触高温时数(C)、浸渍盐酸的时间(D)等四个因素,通过正交设计试验,探索了各因素对实用孵化率的效应。结果表明:A、B、D三因素对孵化率影响较大,C较小。四个因素之间存在交互作用,生产实践中应重视综合条件的选择。各品种对因素水平组合的适应性存在显著差异,东34、苏12两品种适应范围较广,浙农1号较窄,在本试验范围内没有一个因素水平组合能使东肥的孵化率达到满意程度。浙农1号的浸酸时间效应特别明显,因此在短期冷藏情况下适当延长浸酸时间是能够提高孵化率的。
