Evaluation and yield trials of Tomatillo in New Hampshire
2000
Freyre, R. | Loy, J.B.
Five tomatillo (Physalis ixocarpa Brot. ex Hornem) cultivars available from commercial seed companies ('De Milpa', 'Puebla Verde', 'Purple Tomatillo', 'Tomatillo' and 'Tome Verde') and four Physalis L. accessions (PI 197691, PI 270459, PI 291560, and PI 309812) were grown in 1997 and 1998 at Kingman Research Farm, Durham, N.H. Three manual harvests per plot were performed each year, recording data of total fruit weight, number of fruit and average fruit weight for each genotype. There were statistically significant differences between tomatillo genotypes for all three traits. Statistically significant differences between the 2 years were found for fruit number and average fruit weight per genotype. Over both years, total fruit weight varied from 29.7 to 63.7 t-ha-1 (13.3 to 28.4 ton/acre). Fruit numbers per plant varied from 83 to 330, and average fruit weight varied from 18.0 to 38.3 g (0.6 to 1.3 oz). PI 197691 and PI 270459 performed better than some of the commercial cultivars indicating their potential to be used as germplasm for breeding. A basket-weave trellising system which kept plants upright was tested. This made harvest easier and potentially can be used for tomatillo culture.
