Cowpea aphid-borne mosaic virus; Passiflora; backcrossing; cultivars; disease progression; fruit yield; fruits; heritability; passion fruits; prediction; statistical analysis; variance; Brazil
Abstract:
... Passion fruit woodiness disease induced by Cowpea aphid-borne mosaic virus (CABMV) is currently the most harmful viral disease affecting passion fruit crops. Given the economic importance of this fruit crop in Brazil, it is essential that passion fruit breeding programs invest in developing resistant and productive cultivars. The goals of this study were to estimate genetic parameters of agronomic ...

agronomic traits; backcrossing; flowering; fruit yield; fruits; genes; genotype; heat tolerance; microsatellite repeats; parents; phenotype; plant height; temperature; Malaysia
Abstract:
... Domestic production of chilli in Malaysia is insufficient which accounted for 52% self-sufficiency level. Poor performance of local varieties under high temperatures above 42°C is one of the major factors affecting chilli production. This study was conducted with the objective of introgress heat-tolerant gene (Hsps) from AVPP0702 donor into Kulai using marker-assisted backcrossing. A total of 68 S ...

Capsicum annuum; backcrossing; fruit weight; fruit yield; fruits; genetic background; genetic variance
Abstract:
... The six basic generations (two parents, [Formula: see text], [Formula: see text] and backcrosses) of 14 crosses developed from nine parents differing in fruits [Formula: see text] and fruit orientation were evaluated to decipher the genetics of three quantitative traits (average fruit weight, fruits [Formula: see text] and green fruit yield [Formula: see text] during the rainly season of 2016 and ...

Abstract:
... Bacterial spot caused by several species of Xanthomonas is a devastating disease resulting in severe fruit yield loss and quality decline in tomato production areas worldwide. Lack of resistant commercial varieties is among the most critical factors limiting the application of integrated management to control the disease. Although sources for resistance to all species and races have been discovere ...

Abstract:
... Knowledge of gene actions and their relative contribution in expression of characters is of great importance. Therefore, four crosses were made among the six parents viz., Doli-5×GBL-1 (cross 1), Doli-5×KS-331 (cross 2), Pusa Uttam×KS-331 (cross 3) and AB 07-02×GOB 1 (cross 4) to study gene actions responsible for inheritance of twelve fruit yield traits. The generation mean analysis in six popula ...

Abstract:
... The goal of persimmon breeding in Japan is to release new cultivars with improved fruit quality characteristics (non-astringency, high eating quality, commercially acceptable fruit size, the absence of cracks, long shelf-life, and good appearance), high and stable fruit yield, and disease and pest resistance. Of particular importance is the pollination-constant non-astringent (PCNA) trait, however ...
