Abstract
‘Atkinson’, a rootknot nematode and Fusarium wilt resistant tomato variety, probably the first of the Rutgers class to bs released to the public, was named in honor of George F. Atkinson who first described the life cycle of the rootknot nematode at Alabama Agricultural and Mechanical College (now Auburn University) in 1889 (1).
Abstract
The name Tabasco has become synonymous around the world with the famous hot sauce by this name, made from ‘Tabasco’ peppers (Capsicum frutescens L.). This aromatic sauce, widely used to enhance the flavor of many fresh and cooked foods, is made by the Mcllhenny Company of Avery Island, Louisiana. The pepper itself is named after the state in Mexico whence it probably came. It was introduced into Louisiana about 1846. Mention was made of its culture and use in a letter to the editors of the New Orleans Daily Delta of December 7, 1849. In this letter entitled “Deer Range - A Model Sugar Plantation” a visitor from the Northwest (St. Louis) praised his congenial host and owner of the plantation, Colonel Maunsel White, for his hospitality and his superior management which “excited our warmest admiration.” His observations on Tabasco peppers are quoted verbatim: “I must not omit to notice the Colonel's pepper patch, which is two acres in extent, all planted with a new species of red pepper, which Colonel White has introduced into the country, called Tobasco red pepper. The Colonel attributes the admirable health of his hands to the free use of this pepper.”
Abstract
A roundleaf mutant in ‘Bighart’ pimiento pepper readily classified in segregating F2 and backcross progenies, is determined by a recessive gene, rl. The rl gene reduces the length of the leaves but not the width, changing the length/width ratio from 1.50 to 1.24. The rl gene does not produce obvious pleiotropic deleterious effects on the plant and could prove useful as a marker gene in producing F1 hybrids or for characterizing new pepper cultivars.
Abstract
‘Auburn 76’ FMN, herein referred to as ‘AU 76’, is an indeterminate true breeding fresh market tomato cultivar named in honor of America’s Bicentennial and released by the Alabama Agricultural Experiment Station (Fig. 1). ‘AU 76’ possesses 3 dominant genes (I, Tm2a and Mi) conditioning, respectively, near-immunity to both Fusarium race 1 (F) and tobacco mosaic virus (M), and resistance to root knot nematodes (N).
Abstract
The heat tolerant tomatoes (Lycopersicon esculentum Mill.) breeding line AU 165 and ‘Nagcarlang’ were compared with the heat sensitive ‘Floradel’ in fruit set, pollen abortion, and embryo sac abortion. The 2 heat tolerant cultivars had a significantly higher percentage fruit set under both moderate and high temperature in spring and summer than did ‘Floradel’, but fruit set of all 3 cultivars was significantly lower at high temperature. The fruit set of all 3 cultivars was markedly improved by hand pollination, indicating that insufficient pollination probably was a major cause of heat sterility at high temperature. Both pollen and embryo sac abortion were minor factors in the reduced fruit set observed. Heat tolerance in the cross AU 165 × ‘Floradel’ appeared to be partially dominant.
