Abstract:
The objective of this study was to evaluate the adaptability and stability of 18 wheat inbred lines and two wheat cultivars (control) to grain yield, plant height, tolerance to aluminum and other characteristics in experiments carried out in acid soil and limed soil conditions, in 2006-2008. The lines 13 and 17, tolerant at 8 and 10 mg L-1 de Al3+, showed high adaptability and stability to grain yield, heavy grains and resistance to lodging. The cultivar IAC-370 and the line 6, tolerant to 4 and 8 mg L-1 de Al3+, were adapted to favorable environments. The line 20, tolerant to 10 mg L-1 de Al3+, was adapted to unfavorable environments and showed good performance for number of spikelets per spike. All lines showed semi-dwarf plant, except the line 3 (dwarf). Superior genotypes were identified to leaf rust resistance (line 12), number of spikelets per spike and grains per spike (line 15), head length (lines 5 and 8) and grains per spikelet (line 18). The most productive genotypes tend to show taller semi-dwarf plant types and heavier grains in acid soil and limed soil condition. The most tolerant genotypes to 2 and 6 mg L-1 de Al3+ in nutrient solution were the most productive in acid soil.
