Progress and Prospect on Research of High Quality Super Rice in Heilongjiang

Abstract: This paper focused on the following four aspects: Firstly,subspecies of rice indica and japonica were used to broaden germplasm resources technology.Secondly,the culture technology was based on germplasm resources of ideal plant type.Thirdly,molecular breeding technology was used.Fourthly,conventional breeding technology was applied to produce super-high-yield rice materials.The research progress of rice high quality breeding technology in Heilongjiang Province was introduced.The technology of soil fertilization,strong seedling culture,suitable planting density,rising temperature by well water,and balanced fertilization were studied with relation to all kinds of trait performances of high quality super rice varieties in cold land.The results showed that suitable plant density was the basis for establishing super-high-yield structure,with high-efficient photosynthesis in the condition of ideal plant type and upright leaves.Promoting prematurity,high-yield,and high-quality were important.The achievements of super rice breeding in cold land were introduced: Longjing 14,Longjing 5 and Songjing 9 et al.The high quality of super rice research in Heilongjiang Province was expected.The development direction of high-quality super rice research and its breeding objective were proposed.

The organisation of plant breeding and genetics in sweden

Abstract: SIXTY years ago the first plant breeding station in Sweden was founded at the village of Svalöf in the southernmost district of Skâne; to-day there are several important institutes, each with branch stations and sub-stations distributed over the country. Most of these institutes and stations are State supported, others are owned by private seed companies, some of which receive State aid for research. Plant breeding has therefore been taken seriously both by the State and by private enterprise. Its justification is to be found in the increased yields of crops over the last fifty years ; in wheat, a 30 per cent. increase has been estimated to be due to improved varieties alone. This fact, together with the comparatively small size but diverse nature of the country, makes the organisation one very suitable for study. Plant breeding and genetics that is controlled by the State is designed to meet three main requirements. (i) Research into new methods of breeding and fundamental knowledge. (2) Breeding improved varieties suited to many different conditions of soil and climate. () The efficient maintenance and distribution of the new varieties after they have been placed on the market. Fundamental research is carried out at the Institute of Genetics, University of Lund, under Prof. Muntzing, and at the Plant Breeding Institute at Svalöf under Prof. Akerman. The Institute of Genetics is also responsible for genetic teaching. These two Institutes have always been in very close touch, and in fact they were at first under one Director, Prof. Nilsson-Ehle. Even now the experimental grounds for the Genetic Institute are provided by the Plant Breeding Institute this dependence has its disadvantages which, however, will soon be removed by a decision to provide a new building with modern equipment in its own experimental grounds at Lund. This, and the proposed doubling of the staff are evidence of the importance attached to the fundamental and teaching aspects. Genetical teaching and research has also been carried out at the Agricultural College established at Ultuna near Uppsala under the direction of Prof. Turesson. This institute is also to be enlarged. The work, which has already been remarkably successful, is chiefly devoted to the production of new crops by acclimatisation, hybridisation and the doubling of chromosome numbers.
