Title: Variability and Biological Studies on Jew’s Mallow.
Author: El Tahir, Mohamed El Mubarak
Abstract: The objectives of this study were to investigate the extent of variability, heritability and interrelationships between the different characters, as well as the performance under relatively low temperature and nutritive value on nine collections of Jew’s mallow. The crop was rendered to five experiments conducted during two seasons in Shambat in a randomised complete block design. A great deal of variability was shown among the different collections. The number of internodes to the first branch and those to the first flower proved to be safe selection indices. Seed yield was found to be a function of leaf number, leaf area and dry weight per plant as well as number of seeds per pod. On the other hand seed yield was negatively correlated to the number of branches per plant. Significant variations were found in the nutritive value of the different collections. The relatively high content of' protein would classify the crop as one of the richest sources of plant protein. On the other hand, the relatively high exalates need further research to be reduced. Relatively high temperatures were found to stimulate vigorous vegetative growth, while relatively low temperatures and short days delayed flowering. It was concluded that the so called "Egyptian" collections may be spoken of as distinctly different cultivars from what was referred to as "Local’ collections. These Egyptian" cultivars would make a good substrate in selection for low temperature tolerant types.
