Resumo: Primary root growth is very important for wheat (Triticum aestivum L.) crop in upland conditions in the State of São Paulo. Fourteen wheat genotypes (mutant lines and cultivars) were evaluated for primary root growth during 7 and 15 days of development in complete and aerated nutrient solutions, in the laboratory. In the first experiment, solutions with three pH values (4.0, 5.0 and 6.0) at constant temperature (24 ± 1°C), and in the second experiment, solutions with the same pH (4.0) but with three temperatures (18°C ± 1°C, 24°C ± 1°C and 30°C ± 1°C) were used. High genetic variability was observed among the evaluated genotypes in relation to primary root growth in the first stages of development in nutrient solutions independent of pH, temperature and growth period. Genotypes 6 (BH-1146) and 13 (IAC-17), tolerant to Al3+ showed genetic potential for root growth in the first stages of development (7 and 15 days), regardless of nutrient solution temperature and pH. Genotypes 14 (IAC-24 M), 15 (IAC-24), 17 (MON"S" / ALD "S") ´ IAC-24 M2, 18 (MON"S" / ALD "S") ´ IAC-24 M3 and 24 (KAUZ"S" / IAC-24 M3), tolerant to Al3+, showed reduced root growth under the same conditions.

O crescimento das raízes primárias é de grande importância para o estabelecimento da cultura do trigo (Triticum aestivum L.) em condição de sequeiro no Estado de São Paulo. Quatorze genótipos (linhagens mutantes e cultivares) de trigo foram comparados quanto ao crescimento das raízes primárias durante 7 e 15 dias de desenvolvimento em soluções nutritivas completas, com arejamento, em condição de laboratório. No primeiro experimento, empregaram-se soluções com três valores de pH (4,0; 5,0 e 6,0) mantendo-se constante a temperatura (24 ± 1°C) e no segundo, utilizaram-se soluções com mesmo pH (4,0), porém com três temperaturas (18°C ± 1°C, 24°C ± 1°C e 30°C ± 1°C). Observou-se grande variabilidade genética entre os genótipos avaliados para crescimento das raízes primárias nos primeiros estádios de desenvolvimento independentemente do pH, temperatura e período de crescimento nas soluções nutritivas. Os genótipos 6 (BH-1146) e 13 (IAC-17), tolerantes ao Al³+ exibiram potencial genético para maior crescimento radicular nos primeiros estádios de desenvolvimento (7 e 15 dias), independentemente da temperatura e do pH das soluções nutritivas. Os genótipos 14 (IAC-24 M), 15 (IAC-24), 17 (MON"S" / ALD "S") ´ IAC-24 M2, 18 (MON"S" / ALD "S") ´ IAC-24 M3 e 24 (KAUZ"S" / IAC-24 M3), tolerantes ao Al³+, apresentaram reduzido crescimento radicular nas mesmas condições.
