Received 07/30/2004.PI 635122. Zea mays L. subsp. maysBreeding. Inbred. TZMI 711. GP-379. Pedigree - Derived from crossbetween maize variety grown in Tanzania, called Nat'l var. and an IITAmaize streak virus resistant population (TZSR), formed by intercrossingfour populations including TZB, TZPB, POP 21 and POP22. Tropicalmid-altitude adapted maize inbred line at the S8 stage of inbreeding;has combined resistance to gray leaf spot, Cerospora zea-maydis, maizestreak virus (MSV), Exserohilum turcicum and Puccinia sorghi, which areprevalent in the mid-altitude ecology in West and Central Africa. Hassemi-dent grain texture and has been assigned to the TZMI102 heteroticgroup. Tassels in 74 days, silks in 79 days and has plant height of 91cm and ear height of 40 cm.PI 635123.
