Book excerpt: Earlier planting to escape summer drought and high temperature has increased the importance of cold tolerance in corn. The objectives of this study were to assess cold tolerance among the corn hybrids using morpho-physiological traits and to classify hybrids into different groups of tolerance. Corn hybrids were subjected to optimum, low, and very low temperatures during seed emergence and seedling growth and morphological and physiological traits were assessed. Variability existed among the corn hybrids for the measured traits. Total, leaf and root weights and cumulative length and length per unit volume were the most important morphological traits in describing hybrid variability. Principle component analysis and total low temperature response index methods were used to categorize hybrid tolerance to low temperature. Based on relative scores assigned in this study and their yield potential in the niche environment, producer could select hybrids to maximize corn production in an early planting production system.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Washington State is a major producer of sweet corn in the United States with ~36,400 ha planted in the semi-arid Columbia Basin annually. Cold spring soil conditions and soilborne pathogenic species of Fusarium, Pythium, and Rhizoctonia can cause significant losses. In 2018, conventional (n = 31) and organic (n = 16) sweet corn fields were surveyed in the Columbia Basin to assess the prevalence of seedling blights. Stand losses ranged from 3.3-47.5% (14.9 ± 10.9%, mean ± standard deviation) and the incidence of stunting ranged from 3.7-23.4% (10.1 ± 5.3%), demonstrating the opportunity to improve sweet corn production. Of 14 species identified from 350 Fusarium isolates obtained from stunted seedlings, F. oxysporum, F. verticillioides, F. solani, and F. equiseti were the most prevalent. Five species and anastomosis groups (AGs) were identified from 66 Rhizoctonia isolates, with R. solani AG 4 the most prevalent. Pythium ultimum was the most prevalent of four species identified from 63 Pythium isolates. Approximately 60% of the Pythium isolates were resistant to the fungicide mefenoxam at 10 and 100 ppm, which might account for some stand losses. Isolates of P. irregulare, P. ultimum, and P. sulcatum were highly virulent on the sweet corn cv. SuperSweet Jubilee, as were isolates of R. solani AG 4 and AG 2, and F. acuminatum, F. graminearum, F. fujikuroi, F. oxysporum, F. proliferatum, F. solani, and F. verticillioides. There was variation in virulence among isolates of a species. Seed germination and seedling vigor are impeded when sweet corn seed is planted in cold soils. Accessions from the sweet corn breeding association panel of the USDA National Institute of Food and Agriculture Specialty Crops Research Initiative Project No. 2018-51181-28419 were planted in the Columbia Basin in spring of each of 2019 and 2020 to screen for cold tolerance. In 2019, 24 of 182 lines tested had greater emergence and vigor than the processing sh2 hybrid GSS 3071. In 2020, 223 of 580 lines evaluated displayed better emergence and vigor than the processing sh2 hybrid GSS 3951. The trials demonstrated significant potential for improving cold tolerance in sweet corn cultivars.
