Conteúdo: 	BRS Petala soybean cultivar was developed by a modified pedigree selection from the cross Bragg X [Braxton*2 X (BR 27*4 X Cristalina)]. It was extensively evaluated under the experimental designation BR95-1985. It is recommended for planting in the states of Goias, Bahia, Minas Gerais, Mato Grosso, Tocantins and Distrito Federal. Petala has determinate growth habit and reaches maturity approximately 139 days after emergence. It has purple flower, tawny pubescence, seeds with black hila and 100-seed weight of 17 grams. Petala has good resistance to both lodging and shattering. Average plant height is 85 cm and is adapted for planting in different regions and planting dates. Petala is resistant to frogeye leaf spot (Cercospora sojina), bacterial pustule (Pseudomonas syringae pv. glycinea) and moderately resistant to SDS (Fusarium solani f.sp. Glycines) and stem canker (Diaphorte phaseolorum). It has also good resistance to root-knot nematode Meloydogine javanica and moderate resistance to root-knot nematode Meloydogine incognita. In performance trials across 27 locations at cerrado region, over 2 years Petala had higher seed yield than the checks Uirapuru, 'FT 104' 'DM 339', 'M-SOY 8800' and 'Garça Branca'. The average seed yield of Petala was 3381 kg/ha in Tocantins, 3069 kg/ha in Minas Gerais, 3447 kg/ha and Mato Grosso and has a yield potential of 4085 kg/ha. It exibits a high stability of seed yield and is best adapted when planted in November at plant populations of 250,000 to 300,000 plants/ha in Minas Gerais, 300,000 to 350,000 plants/ha in Goias and Distrito Federal and 300,000 plants/ha in Tocantins and Mato Grosso. Petala is a high yielding, root-knot nematode resistant soybean cultivar available for soybean farmers.
