Organic Texas Early Grano 502 PRR (175 days)

Released by the Texas Agricultural Experimental Station in 1944. 

1933 began the Texas onion breeding program which was to produce the Mother "Grano 502" which was in the parentage of all SuperSweet onions such as Granex (Vidalia, Maui Maui and NoonDay) and the Texas 1015Y.

Texas early grano forms large globe shaped vidalia-type onions.  Fine eating quality, nicely uniform with a white flesh. Nice flavor that is not too pungent. 

Tolerance to pink root rot.   That is what the "PRR" stands for.  This is an improvement over "Texas Early Grano 502"  Learn more about the history of onions in Texas.

Texas Early Grano is a short day variety, but works well as an indeterminate day variety of onion as well

TIP:  Remember, organic onions are shallow rooted and benefit from ample amounts of water to form proper bulbs.  About an inch a week.
