2013 turned out to be a good year for evaluating new pecan cultivars. The above average rainfall we received this past summer meant that soil moisture would not be a limiting factor in terms of kernel fill. However, the 2013 growing season was significantly shorter and cooler than normal. Lets take a closer look at the kernels inside the shells of three cultivars to see how cooler temperatures can impact nut quality.
previous post, I found the USDA 75-8-9 had more scab on the shucks than USDA 75-8-5. With more scab on the shucks, USDA 75-8-9 had poorer kernel fill than its sister clone. Note that USDA 75-8-9 has flatter, less-plump kernels.
