Description
Technical Field
The invention relates to the field of crop planting, in particular to a planting method for improving seed production yield of recessive genic male sterile two-line rape.
Background
Rape is a main oil crop in China, is a main source of edible oil and feed protein, is a renewable biological resource, and is generally regarded. With the development of science and technology, rape products have been widely used in industry and medicine, become thousands of raw materials of industrial and medical products, and have been used more and more widely. China has made outstanding achievements in the research and application aspects of rape genetic breeding in the world, and the utilization of male sterility is an important way for utilizing the heterosis of crops. The rape mainly adopts two types of Cytoplasmic Male Sterility (CMS) and nuclear male sterility (GMS) in the aspect of utilizing heterosis, the nuclear sterility of the rape in the south of China is mostly used as a recessive nuclear sterility dual-purpose line, and more so in Guizhou province and southwest areas, the province is at the world leading level in the aspects of researching and utilizing the recessive nuclear sterility dual-purpose line of the rape, the variety of the recessive nuclear sterility dual-purpose line is also dominant in production, and meanwhile, the province also is a great province in seed production of the recessive nuclear sterility two-line hybrid rape.
The recessive genic male sterile dual-purpose line is characterized in that 50% of fertile plants in a female parent row are required to be completely removed before the initial flowering period of rape in the seed production process, so that the number of female parent plants in unit area of a field is reduced, and the seed production yield is reduced. The wide-narrow row seed production technology is characterized in that the female parent is planted in the wide-narrow row mode, the male parent is planted in the wide row of the female parent at a certain plant spacing, and the seed production yield can be improved. The technology is a novel hybrid rape seed production technology which is explored by introducing recessive genic male sterile two-line seed production of rape and combining actual continuous research and study of seed production under the inspiration of obtaining higher yield by wide-narrow row cultivation of field crops such as rice, corn, rape and the like. On the premise of ensuring the sufficient pollen quantity of the seed production field male parent, the technology has enough and reasonable female parent plant number in unit area, compared with the traditional seed production mode with the row spacing of 1:6, the technology has the advantages that the male parent does not occupy 1/7 seed production field, namely, 1/7 land is relatively increased for planting the female parent, therefore, the female parent plant number in unit area is increased, and the seed production yield is increased. The wide and narrow row planting of the female parent and the male parent transplanting increase the population quantity of female parent plants, the distribution of the male parent and the female parent in the planting field is more reasonable, the shading among individuals in the middle and later periods of rape is avoided, the improvement of the field plant growth environment such as ventilation and light transmission is facilitated, the growth of the individual agronomic characters of the female parent and the male parent is facilitated, and meanwhile, the pollen of the male parent plants can be more uniformly diffused to the peripheral female parent plants by transplanting the male parent in the wide row of the female parent, so that the yield of seed production is improved.
The seed production of recessive genic male sterile two-line hybrid rape is characterized by that under the condition of a certain climate and environment the yield of seed production is mainly determined by the quantity of female parent plants capable of harvesting seeds in unit area. In the traditional recessive genic male sterility two-line hybrid rape seed production, the male parent and the female parent generally carry out seed production in a line spacing mode of 1:6, and the male parent has one exclusive line, thus occupying 1/7 seed production area and reducing the number of female parent plants in unit area; equidistant distribution of seed production is not favorable for plant growth, and the seed setting rate of female parent plants far away from the father line is lower. The said two-line hybrid rape with recessive genic male sterility has low yield and high production cost. Therefore, how to reasonably arrange the parent and parent population of the seed production field while ensuring the sufficient pollen quantity of the male parent and increase the number of female parent plants in unit area so as to improve the seed production yield becomes an important research topic in the seed production process of the nuclear sterile two-line rape.
