    HARV_CHARCulm strength at harvest - wild(pre-2007)Characterized by gently pushing the tillers back and forth at a distance of about 30 cm. from the ground. This bending test gives some indication of brittleness and resilience. - Recorded at harvest. - Observed in wild species.3 - Moderately strong  
    HARV_CHARLife cycleThe completeness of plant growth in a growing season. Observed in wild species.2 - Perennial  
    HARV_CHARRhizome and stolon formationRhizome and stolon formation. Observed at harvest in wild species.1 - Vegetative crown  
    POSTHARV_CHARGrain thicknessGrain thickness is the lateral diameter (mm) measured from 10 grains as the largest distance between the two lateral sides in the middle part of the caryopsis. Observed at post-harvest in wild species.1.6  
    POSTHARV_CHARGrain widthMeasured as the distance across the fertile lemma and the palea at the widest point. Observed at post-harvest in all species.2.4

    POSTHARV_CHARChromosome numberChromosomes is the DNA-containing linear bodies found in the cell nuclei of plants responsible for the determination and transmissions of hereditary characters. - Number is recorded at post-harvest. - Observed in wild species.24  
    POSTHARV_CHAREndosperm type(pre-2007)Endosperm type. Observed at post harvest in all species.1 - Non-glutinous  
    POSTHARV_CHARLeaf senescence(pre-2007)The leaves below the flagleaf are observed at the time of harvest for their retention of greenness. Observed in all species.2 - Late and slow (2)  
    POSTHARV_CHARSterile lemma shape - wildSterile lemma shape. Observed at post-harvest in wild species.3 - Subulate or setaceous  
    POSTHARV_CHARSpikelet fertility(pre-2007)Spikelet fertility measurement is taken from counts of well developed fertile spikelets in proportion to total number of spikelets on five panicles at harvest. Observed in all species.5 - Partly sterile  
    POSTHARV_CHARGrain lengthMeasured as the distance from the base of the lowermost sterile lemma to the tip (apiculus) of the fertile lemma or palea, which ever is longer. Observed at post-harvest in all species.7.2
