Abstract
The present disclosure provides methods and compositions for producing, detecting and selecting soybean plants and seeds comprising a desired reproductive growth phenotype, such as early maturity, early flowering, late maturity or late flowering. Also provided are marker loci, marker alleles, primers, probes, and kits suitable for identifying and/or selecting soybean plants or soybean germplasms with one or more reproductive growth phenotypes.
Claims23
A method for producing soybean plants or soybean germplasm having an early maturity or early flowering phenotype, the method comprising:
- a. crossing a first soybean plant or soybean qermplasm with a second soybean plant or soybean qermplasm to form a soybean plant or soybean germplasm population, wherein the first soybean plant or soybean qermplasm is an elite line;
- b. isolating nucleic acids from the soybean plants or soybean germplasm of the population;
- c. genotyping the nucleic acids for the presence of at least one marker associated with early maturity or early flowering linked to or within a chromosomal interval flanked by and including marker loci BARCSOYSSR_15_0312 and BARCSOYSSR_15_1185, the chromosomal interval comprising a T at a marker locus corresponding to position 126 of SEQ ID NO:
- 1;
- and
- d. selecting one or more of the soybean plants or soybean germplasm comprising the at least one marker associated with early maturity or early flowering.
(canceled)
A method for producing soybean plants or soybean germplasm having a late maturity or late flowering phenotype, the method comprising:
- a. crossing a first soybean plant or soybean qermplasm with a second soybean plant or soybean qermplasm to form a soybean plant or soybean germplasm population, wherein the first soybean plant or soybean qermplasm is an elite line;
- b. isolating nucleic acids from the soybean plants or soybean germplasm of the population;
- c. genotyping the nucleic acids for the presence of at least one marker associated with late maturity or late flowering linked to or within a chromosomal interval flanked by and including BARCSOYSSR_15_0312 and BARCSOYSSR_15_1185, wherein the chromosomal interval comprises a C at a marker locus corresponding to position 126 of SEQ ID NO:
- 2;
- and
- d. selecting one or more of the soybean plants or soybean germplasm comprising the at least one marker associated with late maturity or late flowering.
