Finally, the seed-shooting sub-device moves backward; the seed-setting device moves down its lifter, and the next seed is set in the lifter, as shown in Fig. 11d.
j Grains per panicle and Seed-setting rate in OsHox32-OV and wild type plants.
Hence, the developmental delay exhibited by the fpgs03g mutant during the seed-setting stage suggested that the FPGS Os03g02030 gene played a key role during the seed filling stage.
The photogrammetric analysis showed that digital canopy height data compared well with ground truth data at the flowering and seed-setting stages but were underestimated at the harvesting stage.
Seed coat discoloration is an early indicator of poor quality seed, resulting in dull brown-colored grains (Bodalkar and Awadhiya 2014), which negatively affects grain yield, especially by decreasing the number of filled grains per panicle (or seed-setting rate) and 1000-grain weight (Phat et al. 2005).
GF, grian-filling degree; PH, plant height; HD, heading date; YD, yield; TP, number of tillers per panicle; KGW, grain weight per 1000 grains; SP, spikelet per panicle; GP, number of grains per panicle; SS, seed-setting rate; PL, panicle langth; SDEN, grain density per panicle.
Agronomic traits measured in this study included grain yield per plant (YD), number of tillers per plant (TP), number of grains per panicle (GP), 1000-grain weight (KGW), spikelet per panicle (SP), panicle length (PL), grain density per panicle (SDEN), grain-filling degree (GF), and seed-setting rate (SS).
However, a decrease of CKX activity in the spikes determined the lack of pollen development and not seed-setting phenotype.
This was correlated with the lowered to 50% - 60% CKX activity in 7 DAP spikes and it was not observed in seed-setting plants of biolistic origin.
