TO:0000185	stigma color	"Color of the stigma in a blossoming flower." [Gramene:pankaj_jaiswal, IRRI:SES]	TO:0000754 ! cardinal organ part morphology traitTO:0006012 ! carpel morphology trait
TO:0000186	environmental stress related trait	"OBSOLETE." []	None
TO:0000187	anther color	"An anther morphology trait (TO:1000022) which is the color (PATO:0000014) of an anther (PO:0009066)" [TO:austin_meier]	TO:1000022 ! anther morphology traitWTO:0000044 ! morphology
TO:0000188	drought sensitivity	"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 reproductive stage to cause severe drought injury. Leaf rolling precedes leaf drying during drought. Repeated ratings are recommended through progress of the drought." [IRRI:SES]	TO:0000394 ! drought related trait
