BREEDING OF CYTOPLASMIC MALE STERILE LINE DERIVED FROM ORYZA MINUTA PRESL. AND IDENTIFICATION OF ITS RESTORING AND MAINTAINING RELATIONSHIP
摘要
Abstract
Xiaoye 1A was obtained through nuclear substitution of the natural male sterile individuals from Oryza minuta Presl. with the nuclear of outstanding progenies of Y58S/ Neixiang B by backcrosses. Because of the male sterile cytoplasm derived fromOryza minuta Presl., it’s named as the XY type male sterile cytoplasm. The results showed that the male sterile line with XY cytoplasm was different from WA, ID, K and HL male sterile lines(table 2 and table 3) in the relationship between restorer lines and maintainer lines. Part restorer and maintainer lines of WA, ID, K and HL could be used as the maintainer lines of XY cytoplasmic sterile line, and parts of them could be used as its restorer lines. It was a newly found resource of rice male sterile cytoplasm. XYcytoplasm was free from the genetic confinement of the relationship between the restorer lines and maintainer lines of WA,ID, K and HL, enlarging the circle of maintainer lines so that good cultivated cultivars could be developed into fine male sterile lines. Therefore, the creation of the XY type sterile cytoplasm, not only enriches the genetic diversities of hybrid rice, but also opens up a new way to breed the high standard of fine quality male sterile lines, and substantially improve the grain quality of hybrid rice.关键词
