Table 1 Classification of rice panicles and florets for categorization of anther development stages

From: Analysis of anther transcriptomes to identify genes contributing to meiosis and male gametophyte development in rice

  Anther Development
  (PMA) Pre-meiotic anther (MA) Meiotic anther (SCP) Anther with single celled pollen (TPA) Anther with tri-nucleate pollen
Anther development stage [47] Stage 3-5 Stage 6-8 Stage 9-10 Stage 12-14
Anther length (mm) 0.35-0.45 0.50-0.85 0.90-0.95 2.0-2.5
Floret length (mm) 1.5-2.5 3.5-6.0 7.0-7.5 >8.0
Panicle length (cm) 1.0-5.0 6.0-11.0 8.0-15.0 25.0-30.0
  1. Note: Panicle, floret and anther length indexing is standardized only for IR64 cultivar of Oryza sativa subsp. indica, and may vary in different cultivars of rice
