A Computer Program for Record-keeping and Seedling Evaluation in Fruit Trees

Abstract

Data collection and processing in fruit-tree breeding programs have been performed mostly manually, which is time-consuming and also can be the source of transcription errors. Breeders recently have had opportunities to implement a wide range of computer applications. These have included estimating the structure and genetic variation of populations (Dowling and Moore, 1984) and linkage and mutation frequency analysis (St. John et al., 1983). The availability of directly applicable programs, such as genotype-environment interaction characterization (Kang, 1985) and germplasm bank management (Styles et al., 1985), allows for increased effectiveness. Fruit breeding programs have used data processing procedures to optimize operational management (V. Beres and R. Scorza, personal communication). Except for the use of punch cards (Fogle, 1974), computerization of procedures is scarcely mentioned in the literature, except, recently, in forestry research for direct field data collection

Evaluation of a large apricot germplasm collection for fruit skin and flesh acidity and organic acids composition

“…Other than a crucial ripening index for establishing the proper harvest time, sugars and acids content are important criteria for apricot characterization (Bassi and Selli, 1990;Bassi and Negri, 1991;Souty et al, 1991). Compared to peach, apricot has not been clearly differentiated for acids content (e.g., acid and lowacid types), either based on the fruit juice pH or titratable acidity (TA).…”

“…In particular, the malate-citrate ratio appeared extremely variable in apricot, ranging from 0.2 to 8.8 (Gurrieri et al, 2001). Some accessions showed the ability to selectively accumulate malic or citric acid in mesocarp cells (Bassi and Selli, 1990). This work investigates fruit acidity and OAs patterns in flesh and skin within an apricot germplasm collection of 164 accessions.…”

Morfološka i kemijska analiza introduciranih sorti nektarine u Hercegovini

“…Colarič et al (2004) state that the content of total acids for the studied Venus cultivar was (11.50 g/kg), which is in contrast with the results obtained in this research. Bassi and Selli (1990) state that the content of total acids in nectarine cultivars from 10 to 16 g/kg may result in unsatisfactory taste and aroma. In the research Rakonjac and Živanović (2008) state that the cultivar Venus had a content of total acids (0.98%, 1.04%, 1.07% and an average of 1.05%), while in the paper Özkan and Özdil (2012), state that the average content of total acids for the cultivar Venus amounted to (1.37 g/l).…”

Performance of Different Peach Varieties at Lower Altitude (4000 ft) of Murree Hills

“…However varieties with TA lower than 0.9 % is minimum limit for low acidity peaches (Hilaire, 2003) because during maturity total soluble solids increases and acidity of fruit decreases during ripening stage (Padda et al, 2011). In peaches ripening index serve as major organoleptic quality triat in case of mature fruit and used as index of quality (Bassi and Selli, 1990).…”
