A Review of on the Spikelet Number in Rice
Authors(7) :-Ali Sattari, ZA-Jahantigh Haghighi, HO-Nohtani, MO-Noorozi, Ab-Nokhbeh Zaeim, K-Moradi, Na-Mirzaie Amirabad Grain yield of rice (Oryza sativa L.) has four components: panicle number, total spikelet number per panicle (TSN), grain weight and spikelet fertility. There is wide variation in TSN among cultivated rice varieties and it is one of the targets of breeding programs to improve rice yield. Many hypotheses have been proposed to explain ecophysiological process that determines spikelet number per unit area. Nitrogen is one of the most yield-limiting nutrients in crop production, and its proper management is essential for improving grain yield. Grain number is linearly correlated with total plant N content. Nitrogen fertilizer might affect CKs levels to increase rice flower numbers. To identify the loci controlling panicle architecture, QTLs for panicle traits such as number of primary or secondary branches and spikelet number per primary or secondary branch have been mapped and studied. QTLs for TSN have been identified using various segregating populations, including F2 populations, recombinant inbred lines (RILs), and doubled haploid (DH) lines.
