Tillering to maturity stages
  • Plants have a normal colour; rate of growth and flowering normal.  

  • Plants slightly stunted; growth slightly retarded.  

  • Plants moderately stunted, leaves yellowish & development delayed.  

  •  Plants severely stunted, leaves yellow and development delayed and panicles poorly exserted.  

  •  Plants severely stunted, with leaves brown, development much delayed and panicles not exserted.

VI. Drought sensitivity  

Note:  
Drought sensitivity is highly interactive with crop phenology, plant growth prior to stress and timing, duration and intensity of drought stress. For many soils, it takes at least 2 rainless weeks to cause marked differences in drought sensitivity during the vegetative stage and at least 7 rainless days during the productive stage to cause severe drought injury. Leaf rolling precedes leaf drying during drought. Repeated ratings are recommended through progress of the drought. Record the stage of plant growth when the stress occurred and the number of stress days.  

VII. Drought recovery#  
  • 90-100%  

  • 70-89%  

  • 40-69%  

  • 20-39%

#: Scores are taken after 10 days following soaking rains or watering. Indicate degree of stress before recovery.

14. IX. Stem Elongation  
  • Best elongation response

  • Response better than that of elongation, semi -dwarf, but not as good as than of the best local floating variety.

  • Response similar to that of elongating, semi dwarf.  

  • Response better than that of the non  - elongation semi -dwarf but not as good as than of elongating semi-dwarf.  

  • Poorest elongation or none

(a)
For greenhouse screening count for % survival(s) of test entries and resistant control entry such as FR 13A. Compute for % comparative survival value as follows:  
% survival of entry
----------------------------- * 100
% survival of control
(b) For field evaluation, the period of submergence varies and often is not under full experimental control. Record actual % of plants that survived.  
16. XI.  Kneeing ability  
  • Tiller angle greater than 45º for 50% of tillers.  

  • Tiller angle greater than 45ºfor 25% of tillers.

  • Maximum tiller angle is less than 45ºfor 50% of tillers (tiller angle greater than 45ºfor 1 or 2 tillers).

  • Maximum tiller angle less than 30 .

  • No kneeing
