Do you know what 3,890,253 tons looks like? Well those are the numbers for the 2019 California crush report. It rivals 2014's numbers but not good news for farmers. Read all about it here:

This morning I found that were bleeding. This afternoon I found several displaying bud-break on February 19th...a bit ahead of the "normal" March 10-20th time for Fresno County. Not ready for the 2020 season to start just yet.

The 2020 season will commence shortly. bleeding has been spotted throughout the San Joaquin Valley. Cold temperatures & sporadic rain is in the forecast for the next 6 weeks. Surely, unusually warm weather will be experienced too, adding to the climate rollercoaster.

Broad swath of California on track for driest February on record, based on precipitation to date and high confidence forecast of minimal further precipitation by March 1. February is historically peak of rainy season across much of California.

Dr. Markus Keller on drought stress at budbreak: shoot growth & yield maximized at 3-4% below field capacity. If no sapflow (bleeding) when it normally would be, better irrigate

Is California headed back into drought, or did it ever leave one?

Dr. Clark on increasing genetic diversity of grape breeding programs: "it's like magic", and continues to manifest in subsequent generations, & interact with environment in diverse locations

Dr. John Clark, University of Arkansas, reviewed UA breeding program, & collab w/ IFG (leading to success w/ 'Cotton Candy', among others). Vision to develop eastern USA table grapes in challenging climate required unique germplasm, thereby expanding global flavor & texture

Lifetime of variety depends on how well it was tested before release, how growers treat it, and how easy it is to improve on its traits

More from Dr. Ramming: decide to keep or cull progeny as quickly as possible, but not too quickly depending on trait. Only release selections that are superior to existing varieties.
