1. 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.
