“…BRS Kampai was released as the first protected fresh peach cultivar in the country. Depending on the climate conditions, the beginning of harvesting for BRS Libra varies from the last week of September to the first of October, i.e., a nearly 50 days earlier harvest than the mean time at the beginning of the program (Raseira 2010). Apart from this cultivar, others such as cv.…”

The peach breeding program of the Brazilian Agricultural Research Corporation (Embrapa), addressing the adaptation to mild winter conditions, is one of the largest in the world and maintains a germplasm collection of nearly 900 accessions. The objective was to estimate the genetic progress in fruit weight (FW) and fruit development period (FDP) resulting from the above program, by analyzing data records of 16 years (2000-2015) of 65 genotypes. Based on samples of ≥ 10 fruits, the mean annual FW (in g) and FDP (in number of days) from full flowering to harvest were determined. In the 16 years, the gain in FDP consisted of respective reductions of about-12.8,-3.3,-2.8 days for canning peach, fresh peach and nectarine. However, the genetic progress in fruit weight was 5.3, 1.4 and-17.9 g fruit-1 for canning peach, fresh peach and nectarine, respectively.

“…One of the procedures adopted was to cross table and canning fruit genotypes and cross the next generation again with an processing-type fruit cultivar or selection (Raseira et al, 2014). Thus, the breeders obtained canning-type cultivars and selections with early or very early maturation (Raseira, 2010;Raseira et al, 2015Raseira et al, , 2018.…”

“…The cycle from flowering to maturation also stirred interest since the longer the cycle, the longer the fruit remains in the orchard and the greater the risk of losses caused by climatic phenomena such as strong winds, hail (Raseira et al, 2014), and/or biotic factors. Very early flowering, although being related to low chilling requirement, is undesirable in some cultivation areas due to the occurrence of frosts (Raseira, 2010).…”

Peach is a traditional crop in the south of Rio Grande do Sul State, Brazil, where 30 to 53 million cans of peaches in syrup are produced annually. All the raw material produced in the region consists of fruits originating from the peach breeding program of the Brazilian Agricultural Research Corporation (Embrapa Temperate Agriculture), which started even before Embrapa at the Experimental Station of Pelotas, Ministry of Agriculture. The objective was to estimate the genetic progress in phenological traits and production of canning peach resulting from the peach breeding program of Embrapa Temperate Agriculture in 53 years. We divided the data records considered in the estimation of genetic progress into two periods, 1964-1984 and 1985-2017, totaling 53 years. The following traits: maturing period, cycle, number of fruits, fruit weight, yield, and soluble solids content were evaluated. We initially tabulated data and analyzed descriptive statistics. Subsequently, we conducted analysis of mixed models and obtained the estimates of genetic progress through meta-analysis. Genetic gain for earliness, shortening the cycle from flowering to maturation, and genetic gain for fruit yield were observed.
