Abstract
Abstract Three lodging-resistant (LR) and 3 lodging-susceptible (LS) paprika pepper (Capsicum annuum L.) lines were grown from transplants at Bixby, Okla., in 1983. Stem diameter at ground level and number of lodged plants were determined monthly from July through November. Stem diameter increased gradually through 14 Oct. and then leveled off. Number of lodged plants increased sharply between 14 July and 15 Aug., and increased slowly thereafter. On all but the 1st date (14 July), stem diameter was negatively correlated with number of lodged plants. On each date, LR lines averaged larger in stem diameter and lower in number of lodged plants than LS lines. Sample plants were harvested on 28 Oct. On the average, LR plants had larger stem diameters at soil level, greater root weights, and lower shoot:root ratios than LS plants but did not differ from LS plants in shoot weight, number of marketable red pods, and cellulose and lignin content in the lowermost 8 cm of central axis stem tissue. Results should aid in breeding for lodging resistance in paprika pepper.
