Corn stalk lodging, which involves the breakage of the stalk below the ear following either bad weather, insect infestation or stormy rain, usually leads to harvest loss, increased harvesting time and higher drying costs. The objective of this study was to develop a method that can classify corn stalk lodging resistance. This method, which employed the maximum equivalent force exerted on a corn stalk, corresponding stalk agronomic traits, and the singular value decomposition (SVD) algorithm, showed that the five corn varieties with different stalk lodging resistance from two planting densities of 60,000 plants/ha and 75,000 plants/ha can be effectively classified. A customized device was designed to measure the equivalent forces. Three factors, including the planting density, the stalk diameter, and the maximum equivalent force with comprehensive contributions of −0.4603, 0.4196 and 0.4068, which are related to principal components, play an important role in the classification of corn stalk lodging resistance. The results showed that the corn stalk lodging resistance decreased with increase in planting density; however, with the increase in stalk diameter and maximum equivalent force, the lodging resistance significantly increased. Corn breeders can develop higher lodging resistance-based corn varieties by using this approach.

The rising population entails enhancement in wheat productivity to ensure substantial food supply which often get hindered by various biotic and abiotic stresses. Lodging, due to rain and high velocity wind causes significant economic and yield losses in cereals. Hence, lodging is emerging as a major hurdle to achieve the required yield targets. Various morphological, biochemical, anatomical and genetic traits contribute to produce a plant competent enough to bear lodging stress. Hence, in this review, we intend to elaborate the cause and impact relationship of lodging and tried to link lodging tolerance traits to field practices to minimize the losses. Because of the complex nature of lodging phenomenon, it is still obscure to identify best correlated traits to screen genotype in breeding programmes. However, the genotypes with best correlated traits like plant height, culm wall thickness should be introduced/selected in breeding programmes to inculcate lodging tolerance in a high yielding variety as in recent era lodging tolerance is a key factor to enhance productivity and farmer's income as well.
