“…Although varieties of some crops may bloom after this end point (e.g. Wagstaffe and Battey, 2006) varietal data is not available for most crops and therefore could not be incorporated. A ctp represents the area of each crop grown in each p within t (as reported by DEFRA 2009DEFRA , 2010a.…”

“…Oilseed rape has also benefited from rising EU demands for biofuels (Stoate et al, 2009) and the advent of cultivars with low glucosinolates and erucic acid content, allowing for use as animal feed (Burgess and Morris, 2009). Fruit crops have also become more important to total UK crop value thanks to advances in growing systems and, in the case of strawberries, breeding cultivars that bear fruit outside of the normal growing season (Wagstaffe and Battey, 2006).…”

“…Several later studies, however, have confirmed that LDs promote flowering in these cultivars especially at high temperatures (Serçe and Hancock, 2005;Sønsteby and Heide, 2007a, b;Bradford et al, 2010). High temperature can cause reversion from generative to vegetative stage especially in SDs (Nishiyama and Kanahama, 2000;Nishiyama et al, 2003;Sønsteby and Heide, 2007b), and it is one possible reason for severe crop losses reported in UK and USA after the periods of unusually high temperatures (Dale et al, 2002;Wagstaffe and Battey, 2006). To tackle this problem, genetic variation in heat tolerance has been found in the Honeoye × Tribute F 1 progeny (Mookerjee et al, 2013), and elite perpetual flowering breeding material with better heat tolerance has been developed (Hancock et al, 2018).…”

Strawberry flowering physiology has engaged the interest of researchers for almost a century after the initial reports demonstrating the photoperiodic control of flowering and vegetative reproduction through stolons called runners. Most strawberries possess a seasonal flowering habit with flower initiation occurring under short days in autumn and flowering during the following spring. Also perpetual flowering genotypes are known in diploid woodland strawberry (Fragaria vesca L.) and octoploid garden strawberry (F. × ananassa Duch.), and recent research have shown that this trait has evolved independently in different species. Studies in the perpetual flowering mutant of woodland strawberry led to the identification of TERMINAL FLOWER1 (FvTFL1) as a major floral repressor causing the seasonal flowering habit in this species and demonstrated that recessive mutation in this gene leads to perpetual flowering. This breakthrough opened an avenue for molecular understanding on the control of flowering by different environmental signals. Different loci control perpetual flowering in garden strawberry including one dominant major locus and additional environmentally regulated epistatic loci. The major gene is called Perpetual Flowering Runnering (PFRU) because it also reduces the number of runners. Growth regulator applications initially demonstrated the role of gibberellin in the control of runner formation, and molecular understanding on the role of gibberellin biosynthesis and signaling in this process has started to emerge. Here, we present current understanding and major open questions on the control of flowering and runnering in strawberries. In order to understand the control of flowering in the context of perennial growth cycle, we also discuss current knowledge on the control of dormancy.

“…It may be that not only maximum daily temperature, but also the amplitude of temperature change, plays a role in the expression of remontancy. Wagstaff and Battey [11,12] has observed that cool night temperatures (13 • C) can offset the negative effects of high temperatures during the day (>26 • C) on floral initiation.…”

BACKGROUND: Flower initiation in strawberry is often classified by photoperiod sensitivity; however, temperature also plays a major role in determining flower initiation. OBJECTIVE: Our goal was to determine the role heat tolerance plays in regulating remontant flowering in a segregating population of strawberry, Fragaria×ananassa. METHODS: Non-remontant (short day)'Honeoye' and remontant 'Tribute' were crossed and 54 progeny were grown in three temperature regimes (17, 20, and 23 • C) under a long photoperiod in the greenhouse and differences in flower and runner formation among the progeny were compared. In addition, clonally replicated individuals of the same family were grown in the field in Michigan and Oregon, so that the extent of heat tolerance observed for each genotype in the greenhouse studies could be compared to their phenotype in the field (remontant vs. non-remontant). RESULTS: A significant Genotype x Environment interaction was observed in the greenhouse studies, indicating that there was a strong genetic component regulating the response of the individuals to increasing temperature. The level of heat tolerance, as defined as the difference in flower numbers at 23 • C vs. 17 • C,showed a continuous distribution among the progeny, indicating polygenic control. The majority of the genotypes that were remontant in the field produced more flowers at 23 • C than at 17 • C in the greenhouse trials. Flower initiation in both the parents was reduced at 23 • C, but 'Tribute' produced significantly more flowers than 'Honeoye' at 23 • C (48.0 vs. 11.3). Most remontant progeny had few runners, although there were some notable exceptions. CONCLUSIONS: Temperature tolerance plays an important role in the flower and runner initiation of remontant genotypes. Genotypes with high heat tolerance can be selected that will more dependably flower in environments with highly variable levels of summer heat.
