“…Transmission of these viruses takes place in a non-persistent manner by aphids, except for ZLCV, which is transmitted by the insect vector thrips (Rezende et al 1997). Virus infection has a variety of symptoms in the field, perhaps because of the particular virus present in the host and possible mixed infections (Borém and Milach 1998). In Brazil, the occurrence of viruses in cucurbit-producing regions is variable and dispersion is dynamic because of the host species, virus species and migratory capacity of these vectors (Moura et al 2001).…”

“…In contrast, breeding for resistance is a long and costly process ( Borém and Milach, 1998) as the selected variants must have durable resistance to the target virus(es), at least throughout the life of the cultivar. Virus resistance can be either specific or non-specific.…”

Virus diseases are significant threats to modern agriculture and their control remains a challenge to the management of cultivation. The main virus resistance strategies are based on either natural resistance or engineered virus-resistant plants. Recent progress in understanding the molecular mechanisms underlying the roles of resistance genes has promoted the development of new anti-virus strategies. Engineered plants, in particular plants expressing RNA-silencing nucleotides, are becoming increasingly important and are likely to provide more effective strategies in future. A general discussion on the biotechnology of plant responses to virus infection isfollowed by recent advances in engineered plant resistance.

“…At the time, also the surge of double haploid techniques and the undeniable increase of computational capacity had captured the attention of this author. This was certainly not the only review foreseeing that genetics and genomics would eventually lead the next breakthrough toward a food secure World (Borem & Kothe Milach, 1998). Bosemark (1995) and Lee (1998) suggested that the use of molecular markers could lead the way for an increase in selection intensity and the possibility to explore wider variability than ever before.…”

At the turn of 2000 many authors envisioned future plant breeding. Twenty years after, which of those authors’ visions became reality or not, and which ones may become so in the years to come. After two decades of debates, climate change is a “certainty,” food systems shifted from maximizing farm production to reducing environmental impact, and hopes placed into GMOs are mitigated by their low appreciation by consumers. We revise herein how plant breeding may raise or reduce genetic gains based on the breeder's equation. “Accuracy of Selection” has significantly improved by many experimental‐scale field and laboratory implements, but also by vulgarizing statistical models, and integrating DNA markers into selection. Pre‐breeding has really promoted the increase of useful “Genetic Variance.” Shortening “Recycling Time” has seen great progression, to the point that achieving a denominator equal to “1” is becoming a possibility. Maintaining high “Selection Intensity” remains the biggest challenge, since adding any technology results in a higher cost per progeny, despite the steady reduction in cost per datapoint. Furthermore, the concepts of variety and seed enterprise might change with the advent of cheaper genomic tools to monitor their use and the promotion of participatory or citizen science. The technological and societal changes influence the new generation of plant breeders, moving them further away from field work, emphasizing instead the use of genomic‐based selection methods relying on big data. We envisage what skills plant breeders of tomorrow might need to address challenges, and whether their time in the field may dwindle.
