Blueberry plant named 'FCM12-045'

Abstract

The new blueberry plant variety ‘FCM12-045’ is provided. ‘FCM12-045’ is a commercial variety intended for the hand harvest fresh market. The new blueberry plant originated from a cross of ‘FF-128’ (female parent, unpatented) by ‘ZF04-002’ (pollen parent, unpatented). ‘FCM12-045’ selected because it flowered and fruited more than most genotypes in a low latitude, zero chill evergreen production system and had larger fruit than the commercial variety Biloxi with a small picking scar. ‘FCM12-045’ also produces significant numbers of flower buds in a zero chill climate, resulting in a harvest window that is more concentrated than ‘Biloxi’, which fruits more heavily on primocanes.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of southern highbush blueberry (Vaccinium corymbosum L. hybrid) plant, referred to as ‘FCM12-045,’ as herein described and illustrated. The new blueberry plant variety ‘FCM12-045’ was selected near Colima City, state of Colima, Mexico in 2012. ‘FCM12-045’ is a commercial variety intended for the hand harvest fresh market. The variety has high vigor, ripens at the same time as the variety ‘Biloxi’, and produces a medium to large berry with good firmness, and a small picking scar on fruit derived from the current season's growth. ‘FCM12-045’ was selected for use in an evergreen production system in areas where zero effective chilling hours may be accumulated. The growing region of Colima, Mexico where ‘FCM12-045’ was originally selected is at a low latitude (˜19.5° N) with a sub-tropical climate. In this region, temperatures rarely fall below 45° F. (the maximum temperature at which blueberry buds accumulate chill units to break dormancy) and day lengths only vary from between 10.8 hours in December to 13.2 hours in June. Under these conditions, many traditional low-chill blueberry varieties (developed in latitudes)25° -35°) do not produce flower buds or flowers. In the case of blueberry varieties that do flower under these conditions, the flowers are produced primarily on the current season's growth that is often referred to as a ‘primocane’ in the blueberry industry. The ‘primocane’ inflorescences tend to be very elongated in form compared to the inflorescence produced at higher latitudes from dormant buds, and the fruit often does not abscise well from the pedicel, resulting in a large picking scar which greatly limits shelf life. The blueberry industry in this area is dominated by the variety ‘Biloxi’. ‘Biloxi’ is one of the few traditional low chill varieties that grows well and produces fruit with a good picking scar in this growing environment. However, ‘Biloxi’ often produces an excessive proportion of small, unmarketable fruit. ‘FCM12-045’ was exceptional because it flowered and fruited more than most genotypes but also had larger fruit than Biloxi with a small picking scar. ‘FCM12-045’ also produces significant numbers of flower buds in a zero chill climate, resulting in a harvest window that is more concentrated than ‘Biloxi’, which fruits more heavily on priniocanes.

SUMMARY OF THE INVENTION

Pedigree and History: The new blueberry plant originated from a cross of ‘FF-128’ (female parent, unpatented) by ‘ZF04-002’ (pollen parent, unpatented).

The cross that produced ‘FCM12-045’ (denominated by the cross code ‘X08-128’) was made in Lowell, Oreg., USA in 2008.

The new blueberry plant variety ‘FCM12-045’ was initially propagated by softwood cuttings in 2012. Rooted plants from these cuttings were field planted in Tala, Jalisco, Mexico and also shipped to Lowell, Oreg., USA in 2013. Additional plants have been propagated via softwood cuttings from the plants established in Tala, Mexico in 2014. The plants sent to Lowell, Oreg. were also propagated via softwood cuttings in 2014 and successfully used to establish in vitro culture lines in 2014.

The seedling family that produced ‘FCM12-045’ was initially grown in 50 cell propagation trays and shipped to Mexico in March, 2011 after the plants had reached sufficient size to be field planted. They were planted in a commercial blueberry field near Colima City, state of Colima, Mexico and evaluated for fruit production and quality beginning in December 2011. ‘FCM12-045’ was selected in 2012 because it was very vigorous, high yielding, highly evergreen, and had a very concentrated ripening period in an evergreen, zero chill production system. After being selected in Colima, ‘FCM12-045’ was propagated by softwood cuttings and a ten plant plot was established in Tala, Mexico (near Guadalajara). The ten plant plot was evaluated for fruit quality and yield in comparison to the standard varieties ‘Biloxi’ and ‘Ventura’ beginning in December, 2013. After two harvest seasons of evaluation, the yield and fruit quality of ‘FCM12-045’ were deemed sufficiently good to warrant launching it as a commercial variety.

The new blueberry plant ‘FCM12-045’ as it grows in Tala, Mexico is distinguished by a highly branched growth habit, with narrowly spaced internodes, and highly evergreen leaves resulting in a rounded plant shape. The new blueberry plant ‘FCM12-045’ has new leaves that are often reddish-orange in hue and very broadly elliptic or even round in shape, urceolate flowers, and firm, large fruit with a moderately dark color and flattened shape. The new blueberry plant ‘FCM12-045’ consistently produces larger fruit than the standard variety ‘Biloxi’, which is a very desirable characteristic.

Plants of ‘FCM12-045’ propagated from softwood cuttings or in vitro are phenotypically stable and exhibit the same characteristics as the original plant. The parents ‘FF-128’ and ‘ZF04-002’ have not been evaluated in the same environment of Mexico that ‘FCM12-045’ was selected in. In California, USA ‘FF-128’ was discarded after one season of evaluation because it did not grow well there. We have very few other notes of the parent ‘FF-128’ except the original selection notes for it from Lowell, Oreg. where it was noted that it had a concentrated ripening period and firm fruit. The parent ‘ZF04-002’ has been much more extensively evaluated. The parent ‘ZF04-002’ is similar to the new blueberry plant ‘FCM12-045’ in that it is very evergreen, with a highly branched growth habit and short internodes. However, the leaves of ‘FCM12-045’ are much more rounded at the apex than leaves of the parent ‘ZF04-002’ which have an acute apex. The fruit of ‘FCM12-045’ is similar in shape to the parent ‘ZF04-002’ but fruit of ‘ZF04-002’ have a much heavier bloom resulting a lighter blue color than ‘FCM12-045’.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘FCM12-045’. The data which defines these characteristics was collected from asexual reproductions of the original selection. Dimensions, sizes, colors, and other characteristics are approximations and averages set forth as accurately as possible. All measurements are the average of five observations. The plant history was taken on mature plants approximately 2 years of age, and the descriptions relate to plants grown in the field in Tala, state of Jalisco, Mexico unless otherwise noted (observations on fall leaf color and some other traits were collected on plants grown in Lowell, Oreg.). Descriptions of fruit characteristics were made on fruit grown in Tala, State of Jalisco, Mexico. Color designations are from “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbery, Harry N. Abrams, Inc., Publishers, New York 1990) unless noted otherwise. Where the Pantone color designations differ from the colors in the photographs, the Pantone colors are accurate.
