Drought and Low-N Conference: TRIAZOLE PRIMING OF MAIZE SEED TO ENHANCE DROUGHT TOLERANCE DURING FIELD ESTABLISHMENT (384 words) |
 | We evaluated the triazole ‘Paclobutrazol’ as a seed primer on two maize cultivars in 1994 and on five maize cultivars in 1995 in field trials conducted at Tlaltizapan, Morelos and at Cocula, Guerrero, and in greenhouse studies at the University of Guelph. |
| In the 1994 trial series, seeds of hybrids ‘P 3288’ and ‘NK TB 8101’ were primed with Paclobutrazol 50 alone and in combination with Ancymidol 25, and grown under severe and moderate drought stress conditions in the dry winter season. |
| The two field trials at Tlaltizapan involved a seedling survival trial with a gradation in levels of irrigation during the establishment phase and a mid-season drought stress trial. |
| Combining ability of different versions of Tuxpeño-based maize germplasm developed at CIMMYT (506 words) |
| In this study, nine different Tuxpeño versions developed at CIMMYT were compared for their combining ability using four testers (two from Tuxpeño and two from ETO Blanco). |
| Thirty-six line x tester crosses and 13 parents were evaluated in two environments at Poza Rica and Tlaltizapan, México during 1991. |
| The improved cross performance of the two hybrid-oriented Tuxpeño versions was due to an increase in their ear length and 100 kernel weight. |
