|
amylose content |
|
|
brown rice protein |
Protein content in brown rice (dehulled grain with pericarp) as described in 54926 |
|
awn presence |
Presence or absence of awns, frequency and length of awns along a panicle was evaluated |
|
blast disease |
|
|
brown rice ratio |
Ratio of unpolished rice grain length to grain width was measured |
|
brown rice length |
Length of the dehulled, unpolished rice grain was measured |
|
grain surface area |
Surface area of the dehulled, unpolished rice grain was calculated. |
|
grain width |
Width of the dehulled, unpolished rice grain was measured |
|
grain volume |
Volume of the unpolished rice grain (dehulled) was measured |
|
flag leaf length |
Length of the flag leaf measured from leaf base to leaf tip |
|
flag leaf lamina width |
Width of the flag leaf measured at the widest portion of the leaf lamina |
|
flowering time |
|
|
hull color |
Color of the hull was visually examinedexamined |
|
leaf lamina pubescence |
Presence or absence of hairs on the leaf blade surface was evaluated |
|
floret number per inflorescence |
Number of flowers (florets) on the primary panicle was counted |
|
primary branch number |
Number of primary branches along the panicle was counted |
|
spikelet fertility |
Percent of spikelets that filled and produced seeds determined as the ratio of seeds per panicle/spikelets per panicle |
|
Panicle length |
Panicle length was measured as the average number of centimeters from the panicle neck to the panicle tip, excluding awns. |
|
Panicle number |
Panicles per plant was calculated as the average number of panicles per plant at harvest. |
|
pericarp color |
Ten seeds per plant were dehulled and then visually inspected; PATO:0000322, PATO:0000323; ECO:0000002; GAZ:00004426 |
|
culm angle |
Average angle of the plant culm with respect to the ground surface at maturity was measured |
|
Plant height |
Plant height was measured in centimeters from the soil surface to the tip of the tallest panicle, excluding the awns. |
|
seed length |
Length of the seed with hull was measured |
|
seed length to width ratio |
Ratio of seed length to seed width was measured |
|
seed number |
Number of seeds per panicle (inflorescence), determined by counting the number of filled spikelets along the main panicle |
|
surface area of grain with hull |
Surface area of the seed with hul was measured |
|
volume of grain with hull |
Volume of the seed with hull was measured |
|
seed width |
Width of the seed with hull was measured |
|
straighthead |
Rated visually based on floret sterility and panicle emergence on a scale from 1 (normal panicle emergence and less than 20% sterility) to 9 (stubby plants with no panicle emergence) |
|
unfilled grain number |
|
|
alkali digestion |
Rice grains were treated with 1.7% KOH and scored for the extent of digestion of the starch based on its level of intactness. |
