Book Description
In a greenhouse study, eight month old plants of red clover cvs Arlington and Florex were evaluated for resistance to Fusarium root rot. Four hundred and fifty genotypes were inoculated with one of three isolates of Fusarium roseum (814, 927, 959) using a cut-root application technique. The degree of Fusarium root rot incidence was evaluated by measuring the vertical discoloration in the taproot from the point of inoculation, and by means of the Horsfall-Barratt scale. Isolate 814 produced a greater degree of infection than isolates 927 and 959. Genetic difference in resistance between and within the two red cultivars were found using isolate 814 and 959, but no difference was found using the less pathogenic isolate 927. [...].

Distant Hybridization of Crop Plants
Author: G. Kalloo
Publisher: Springer Science & Business Media
ISBN: 3642843069
Category : Technology & Engineering
Languages : en
Pages : 282
Book Description
Wild taxa are invaluable sources of resistance to diseases, insects/ pests, nematodes, temperature extremes, salinity and alkalinity stresses, and also of nutritional quality; adaptation; genetic diversity and new species. Utilization of wild relatives of a crop depends largely upon its crossability relations with cultivated varieties. Sev eral wild species are not crossable with the commercial cultivars due to various isolation barriers. Furthermore, in a few cases, hybridiza tion is possible only in one direction and reciprocal crosses are not successful, thus depriving the utilization of desired cytoplasm of many species. However, techniques have been developed to over come many barriers and hybrid plants are produced. New crop species have been developed by overcoming the F 1 sterility and producing amphidiploids and such crops are commercially being grown in the field. The segregation pattern ofF 1 hybrids produced by distant hybridization in segregating generations are different from the intervarietal hybrids. In former cases, generally, unidirectional segregation takes place in early generations and accordingly, selec tion procedures are adopted. In most of the cases, backcross or modified backcross methods have been followed to utilize wild species, and thus numerous types of resistance and other economical attributes have been transferred in the recurrent parents. Protoplast fusion has been amply demonstrated in a number of cases where sexual hybridization was not possible and, as a result, hybrids have been produced.
