Another standout variety was Guatemalan Green Ayote Landrace Butternut which yielded well in comparison to other squash varieties we were trialing this year. Some varieties ended up aborting all of their fruits and did not yield a single squash due to drought stress but the Ayote landrace put forth a very admirable crop without irrigation. The flesh was sweet, with high dry matter and great flavor and is lasting very well in storage. We crossed Ayote with a mini butternut, which also fared quite well in the drought. Crossings of these two squash make up our Ancestors Butternut Landrace, which has been a very exciting project to embark upon. The Ancestors Butternut breeding project was born out of a response to the increasing difficulty to grow kabocha-type squashes in the Northeast. We recall even just ten years ago how easy it was to grow kabocha squash and how widely available they were at farmers markets. Since squash vine borers have become a consistent issue, growing kabochas, buttercups and other C. maximas organically has become much more difficult. This is where moschatas enter the picture. C. moschatas (butternut and tropical squash types) are resistant to vine borers because they have solid, woody stems. Maximas, on the other hand, have very succulent fleshy stems, delicious to the borers! Our objective is to produce squash with similar eating quality to C. maxima (think high dry matter and high sugar content) with the borer resistance of moschatas. We are using varieties that have already been worked upon, such as Honeynut (a moschata and maxima interspecific cross) and other varieties that exhibit inherent superior taste experience, such as the Guatemalan Green Ayote Landrace Butternut. We are also creating interspecific crosses between C. moschata and C. maxima. An interspecific cross is a naturally occurring cross pollination of different species of the same genus. A rare occurrence in nature, interspecific crosses become more possible with human intervention. Rutabagas, Tetsukabuto squash, mustard greens and Ethiopian kale are all examples of naturally occurring or human created interspecific crosses.
