Susceptibilidad de diez cultivares de maíz (Zea mays L.) a cuatro poblaciones de Meloidogyne incognita
The susceptibility of ten corn cultivars (the bybrids X105A (XA) and Tico H4 (T4), and the composites Yonsafwala 7435 (Y), Tuxpeño 1 (Tx1), Poza Rica 7422 (P22), Tlaltizapan 7322 (Tz), Honduras 7322 (H), Poza Rica 7322 (PA-22), Tocumen 7428 (T) and Gemiza 7421 (G) to the attack of four Meloidogyne incognita populations (M-50, M-53, M-55 and M-56) was evaluated mider greenhouse conditions. Population M-50 significantly increased the fresh weight of tops of H wbereas M-50 and M-53 reduced it in XA M-50 significantly reduced the height of T and Tx1 while M-55 and M-56 significantly increased the height of P22 Population M-55 reduced the height of Y The number of root galls caused by M-50 in TxI was significantly lower than the one cansed by M-53; the same was true regarding the Y cultivar with population M-55 in comparison with M-56. The number of egg masses produced by M-55 in Y was lower than that produced by M-56. The number of egg masses was lower in XA than in any of the other nine cultivars.
