Total grains per panicle (TG)
All the grains of the sampled plants were counted.
After harvest
Filled grain percentage (FGP)
No. of fertile grains per panicle of the sampled plants were counted and then FGP was calculated as
After harvest
Panicle length (PL) (cm)
The length of the main axis of the panicle is measured from base to the tip.
After harvest
Grain length (GL) (mm)
The distance from the base of the lowermost glume to the tip (apiculus) of the fertile lemma or palea, whichever was longer was measured.
After harvest
Grain width (GW) (mm)
The distance across the fertile lemma and palea at the widest point was measured.
After harvest
Kernel length (KL) (mm)
Ten milled grains were randomly taken and their length was measured.
After milling
Kernel width (KW) (mm)
Ten milled grains were randomly taken and their width was measured.
After milling
Flag leaf length (FLL) (cm)
The length of the flag leaf, from the ligule to the tip of the blade, was measured.
7 days after anthesis
Flag leaf breadth (FLB) (cm)
The breadth at the widest part of the flag leaf was measured.
7 days after anthesis
Effective tiller (ET)
Tillers with a panicle filled with grains were counted.
At maturity
Plant height (PH) (cm)
Length measured from the soil surface to the top of the tip of the panicle was measured.
At maturity
Thousand-grain weight (TGW) (g)
1000 grains were randomly selected and then the weight was measured.
After harvest
Grain yield (GY) (ton/ha)
The total yield per plot and its moisture percentage were measured and then the yield per hectare at 12% moisture was estimated using the formula (Paudel, 1995, as cited by Amgain and Dhakal [19]:
