A technique for reciprocal root‐scion grafting of soybeans is described using plastic straws and small rubber bands in place of pressure tape commonly employed. The technique described is simpler and faster than the pressure‐tape method of grafting; success of greater than 90% was obtained in our experiments.
A total of 2,291 wheats were evaluated for seedling resistance to Septoria nodorum (Berk.) Berk. in the greenhouse. The 20 most resistant lines were selected for evaluation of the adult reaction. Comparisons of selected lines were made on the basis of: (i) grain weight; (ii) kernel number; (iii) delay in heading; (iv) leaf damage; and (v) reduction in head weight. Three Triticum timopheevi Zhuk accessions, one Triticum fungicidum Zhuk, and six common wheats (Triticum aestivum L.), C.I. 12373; C.L 14032; Redhart, C.I. 8898; RedChlef, C.L 12109; Knox 62, C.I. 13701; and Hadden, C.I. 13488, were the 10 most resistant lines
Relatively high levels of field resistance to anthracnose, Colletotrichum trifolii, were observed in the alfalfa variety ‘Cherokee’ and in an experimental line MSHp6. Severe anthracnose infection on susceptible varieties, ‘Saranac’ and ‘Iroquois,’ caused 25 to 30% losses in forage yield and stand, as well as losses in plant vigor the following spring. We believe that the importance of anthracnose injury in warm humid areas has been underestimated. Resistance in Cherokee and MSHp6 was attributed to recurrent cycles of field selection in North Carolina and Maryland, respectively, where anthracnose often occurs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
