Jc. Felicio et al., AGRONOMIC BEHAVIOR AND TECHNOLOGICAL EVAL UATION ON TRITICALE GENOTYPES FOR THE STATE OF SAO-PAULO, BRAZIL, IN 1988-89, Pesquisa agropecuaria brasileira, 28(3), 1993, pp. 281-294
Twenty three triticale cultivars plus two wheat cultivars were evaluat
ed at different locations of the State of Sao Paulo, Brazil, during th
e period 1988-89. Grain yield, hectolitric weight (HW), weight of 1000
grains, and the simple correlation between these parameters, resistan
ce to diseases and bread qualities were also evaluated. The triticale
cultivars Nutria 440, Tarasca 87, Nutria 7272 and IAC 1 showed high re
gional adaptation. The wheat cultivar IAC 21 presented a high value fo
r hectolitric weight differing from the triticale cultivars, but for t
he weight of 1000 grain this wheat cultivar did not differ from the Nu
tria 440, Nutria 7272 and IAC 21 triticale cultivars, and from the IAC
60 wheat cultivar. The.Nutria 440, Tarasca 87, ICT 8804, Cananea 79,
ICT 8709 and ICT 8801 triticale cultivars exhibited resistance to leaf
rust. All triticale and wheat cultivars under study showed susceptibi
lity to Helminthosporium sp. Considering the technologic evaluation, I
CT 8803 exhibited good performance, showing a specific volume of 17,7%
superior in relation to the wehat IAC 60, used as control.
