Abstract
A method of enhancing grain yield of a Gramineae plant is provided. The method comprises: (a) crossing a recipient plant with a donor plant comprising a sequence variation in a TPR allele, said sequence variation imparting enhanced grain yield; and (b) selecting a progeny plant of said crossing comprising said sequence variation by identifying said variation, said progeny plant being characterized by an improved grain yield relative to said recipient plant. Also provided are plants and processed products resultant of the method.
Claims7
A method of enhancing grain yield of a rice plant, the method comprising:
- (a) crossing a recipient rice plant with a donor rice plant comprising a translocated promoter region (TPR) allele of haplotype I, wherein said haplotype I is defined as comprising an A at nucleotide 31010249, a G at nucleotide 31013745, a G at nucleotide 31019010, an A at nucleotide 31023080, a T at nucleotide 31024549, a C at nucleotide 31026954 and an A at nucleotide 31035009, wherein numbering of said haplotype 1 is with respect to chromosome 2 of Samba Mahsuri and whereas said donor rice plant is indica and said recipient rice plant is indica or japonica;
- and
- (b) selecting a progeny plant of said crossing comprising said TPR allele of haplotype I by identifying said haplotype I, wherein said identifying said haplotype I is by sequencing, said progeny plant being characterized by an improved grain yield relative to said recipient plant.
