Resumo: This study aimed to characterize the chilling requirement of 18 peach tree cultivars during dormancy, as well as to zon the cultivars to the ecophysiographic regions of the Rio Grande do Sul (RS). 'Flor da Prince', 'Planalto', 'Vanguarda', 'Robidoux', 'BRS Fascínio', 'Cerrito', 'Libra', 'Chimarrita', 'Atenas', 'Maciel', 'Kampai', 'Granada', 'Santa Aurea', 'Barbosa', 'Della Nona', 'Mandinho', 'Bonão' and 'Baby Gold' twigs were collected in the field in April/2019. The cuttings were submitted at 7.2°C and two cold times (200 and 400 CH). After each cold time, the cuttings were transferred at 20ºC to induce the budburst. Cultivars were stratified by chilling requirement into three classes: low (≤200 CH), medium (201-400 CH) and high (> 400 CH). The chilling requirement of the cultivars was related with the budburst and harvest dates in the field and the cultivars were zoned in the ecophysiographic regions of the RS Estate, based on the map of CH. 'Flor da Prince', 'Vanguarda', 'Mandinho', 'Libra', 'Kampai', 'Granada', 'Bonão' and 'Cerrito' needed ≤200 CH to overcome dormancy. 'BRS Fascínio', 'Baby Gold', 'Atenas', 'Maciel', 'Santa Aurea' and 'Chimarrita' required 201-400 CH. 'Barbosa', 'Planalto', 'Della Nona' and 'Robidoux' required >400 CH. The budburst and harvest dates of the cultivars in the field are related to the chilling requirement of the genotypes. Low chilling requirement cultivars can be grown throughout of the RS state; those of medium chilling requirement are limited to the cultivation only on the western border; and those of high chilling requirement are recommended mainly for Serra Gaucha, Campos de Cima da Serra, part of the Planalto Médio and of the Serra do Sudeste.

O objetivo desse trabalho foi quantificar a necessidade de frio na dormência de 18 cultivares de pessegueiro. Estacas de ‘Flor da Prince’, ‘Planalto’, ‘Vanguarda’, ‘Robidoux’, ‘Fascínio’, ‘Cerrito’, ‘Libra’, ‘Chimarrita’, ‘Atenas’, ‘Maciel’, ‘Kampai’, ‘Granada’, ‘Santa Aurea’, ‘Barbosa’, ‘Della Nona’, ‘Mandinho’, ‘Bonão’ e ‘Baby Gold’ foram coletadas a campo em abril/2019. Submeteu-se as estacas em câmaras incubadoras a 7,2°C e dois tempos de frio (200 e 400 HF). Após cada tempo de frio, transferiu-se as estacas para 20ºC para indução da brotação das gemas. Estratificou-se as cultivares quanto a exigência de frio em três classes: baixa (≤200 HF), média (201-400 HF) e alta (>400 HF). Relacionou-se a exigência de frio das cultivares com as datas de brotação e colheita a campo e zoneou-se as cultivares às regiões ecofisiográficas do RS, baseado no mapa de HF. ‘Flor da Prince’, ‘Vanguarda’, ‘Mandinho’, ‘Libra’, ‘Kampai’, ‘Granada’, ‘Bonão’ e ‘Cerrito’ necessitaram ≤200 HF para superar a dormência. ‘Fascínio’, ‘Baby Gold’, ‘Atenas’, ‘Maciel’, ‘Santa Aurea’ e ‘Chimarrita’ necessitaram de 201-400 HF. ‘Barbosa’, ‘Planalto’, ‘Della Nona’ e ‘Robidoux’ necessitaram >400 HF. As datas de brotação e colheita das cultivares a campo relacionaram-se com a exigência de frio dos genótipos. As cultivares de baixa exigência podem ser cultivadas em todo o Estado; as de média exigência limitam-se ao cultivo apenas na fronteira oeste; e as de alta exigência são recomendadas principalmente para Serra Gaúcha, Campos de Cima da Serra, parte do Planalto Médio e da Serra do Sudeste.Departamento de Diagnóstico e Pesquisa Agropecuária.
