Pepper cultivation requires a great amount of manual labor, especially for varieties needing support stakes to prevent them bending or breaking in heavy winds or rain. In Korea, it is recommended to secure support stakes and string lines carefully, so as to minimize the risk of damage caused by typhoons. The harvesting of peppers is a labor-intensive process with low rates of mechanization.The removal of stakes is particularly time-consuming during mechanical harvesting, and lodging is a major issue during cultivation and mechanical harvesting. Given increased mechanization during pepper harvesting, it is important to consider these issues when undertaking variety development and cultivation method improvements. Further research and development are required to improve cultivation practices and develop pepper varieties that are more resistant to lodging. Therefore, this study aimed to investigate the impact of different cultivation methods on pepper lodging, thus broadening our knowledge on the desirable architecture of pepper plants required for lodging tolerance.

The term ‘lodging’ in agriculture is usually used when the crops fall from their upright position before harvesting. Various factors may be responsible, including inherent weaknesses in the stem, resulting from low lignin content or small root systems.Weather, such as strong winds or rains, will also likely increase lodging. Insect or disease damage can also weaken the plants, and cultural practices, such as fertilization, irrigation, and cultivation techniques, may increase the risk. Most of the research studies on lodging have been undertaken on cereal crops, but this is also an issue with many vegetable crops, and especially those that require mechanized harvesting. In this review, the issue of lodging in solanaceous vegetable crops is discussed, with an emphasis on the key risk factors and potential areas for future research that can identify damage mitigation strategies.

‘Gwangyoung’, a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2018. The cultivar ‘Gwangyoung’ has leaves of wide width, medium length, and green color, and spikes of medium length and yellowish-brown color, and a large grain of yellowish-brown color. The heading date of the cultivar ‘Gwangyoung’ was April 22 which was similar to check cultivar ‘Shinyoung’. Its tolerance or resistance to cold, lodging, wet injury powdery mildew, and leaf rust were also similar to those of the check cultivar. The leaf blade ratio of ‘Gwangyoung’ (27.5%) was higher than that of ‘Shinyoung’ (21.2%). The average forage fresh and dry matter yield of cultivar ‘Gwangyoung’ at milk-ripe stages were 50.0 and 17.6 MT ha-1, respectively, which were higher than those (47.7 and 17.1 MT ha-1) of the check cultivar. The silage quality of ‘Gwangyoung’ was lower than that of the check cultivar ‘Shinyoung’ in crude protein content (5.3%) and total digestible nutrients (61.3%), while was higher than the check cultivar in neutral detergent fiber (58.2%) and acid detergent fiber (34.9%). ‘Gwangyoung’ showed the silage of 1 grade and a grain yield of 6.03 MT ha-1.

‘Choyoung’, a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar ‘Choyoung’ has the leaves of medium width, long length and green color and a medium grain of brown color. The heading date of the cultivar ‘Choyoung’ was April 30 which was 2 days earlier than that of check cultivar ‘Shinyoung’. Its tolerance or resistance to cold, wet injury, powdery mildew, and leaf rust was similar to those of the check cultivar. But the resistance to the lodging of cultivar ‘Choyoung’ was stronger than that of the check. The average forage fresh and dry matter yield of cultivar ‘Choyoung’ at milk-ripe stages were 40.5 and 15.7 MT ha-1, respectively, which were similar to those (40.3 and 16.1 MT ha-1) of the check cultivar. The silage quality of ‘Choyoung’ was higher than that of the check cultivar ‘Shinyoung’ in crude protein content (5.9%), while was similar to the check cultivar ‘Shinyoung’ in acid detergent fiber (33.9%), neutral detergent fiber (57.3%), and total digestible nutrients (62.2%). It showed a grain yield of 5.59 MT ha-1, which was 38% higher than that of the check cultivar ‘Shinyoung’ (4.05 MT ha-1). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than -10 ℃.

'Dakyeong' (Avena sativa L.), a winter oats for forage use, was developed by the breeding team at National Institute of Crop Science, RDA in 2016. It was derived from a cross between ‘CI7505’(IT133304) and ‘Swan’(IT197920). Subsequent generations followed by the cross were handled in bulk and pedigree selection programs at Iksan and Jeonju, respectively. After preliminary and advanced yield test for 2 years, ‘SO2004009-B-B-10-8-3-9’, designated as a line name of ‘Gwiri91’, were subsequently evaluated for earliness and forage yield during 3 years in four parts such as Jeju (upland), Yesan (upland), Iksan (upland), and Jeonju (paddy), from 2014 to 2016, and finally named as ‘Dakyeong’. Cultivar ‘Dakyong’ has leaves of dark green color, thick diameter culm and long grain of brown color. Over 3 years, the heading date of ‘Dakyeong’ was about 5 days earlier than that of check cultivar ‘Samhan’ (April 30 and May 5, respectively), and their average forage dry matter yield harvested at milk-ripe stage was higher 12% (15.7 tone ha-1) than 14.0 tone ha-1 of check cultivar. Cultivar ‘Dakyeong’ was lower than the check cultivar ‘Samhan’ in terms of the protein content (6.1% and 7.0%, respectively) and total digestible nutrients (62.1%, and 62.5%, respectively), while the TDN yield was more than the check (7.79 tone ha-1 and 7.64 tone ha-1, respectively). Fall sowing cropping of ‘Dakyeong’ is recommended only in areas where average daily minimum mean temperatures in January are higher than -6°C, and it should not be cultivated in mountain areas, where frost damage is likely to occur.
