Effect On Yield

AbstractRelation between morphological traits of the root system and yield related traits is an important issue concerning efforts aiming at improving of ideotype of cultivated plants species, including pea. In this paper, to analyse the dependency between traits describing the root system morphology and yield potential, Person’s andSpearman's_correlations as well as canonical correlations were used.Root system was analyzed in 14 and 21 day-old seedlings growing in blotting-paper cylinders. Yield potential of pea was analysed in a field experiment. Results of Person’s and Spearman's_correlations revealed that number of lateral roots and lateral roots density were correlated witch yield related traits. Correlation between root length and shoot length was observed only for 14 day-old seedlings. The result of canonical correlations revealed that number of lateral roots and lateral roots density had the largest effect on yield related traits. This work highlights, that in order to improve the yield of pea it might become necessary to understand genetic determination of morphological traits of the root system, especially number of lateral roots.

Or Genes

IT IS the part of wisdom when about to give a dissertation which one hopes will at once instruct and entertain, to provide at the outset some definition of the subject matter. Genetics is the study of the heritable components of variation; the heritable factors which determine the range or extent of diversity. So, genetics is concerned with heritable differences and likenesses between individuals and between species. One emphasizes the differences because one can be certain of genetic determination of a particular characteristic only when it exists in a population in two or more alternative forms. It is the variants which catch the eye and hold the attention of the investigator, and which by their presence suggest more than one form of the gene or genes which determine that particular characteristic. I would like in what follows to present some examples of investigations of some aspects of genetics in human populations. ADRENAL HYPERPLASIA Several years ago Dr. Melvin Grumbach and I studied the genetics of adrenal hyperplasia, using as our material the patients of Dr. Lawson Wilkins. Since the disease occurs in more than one member of a sibship and since parents are unaffected, we suspected that it was genetically determined and that the affected patient possessed a double dose of a mutant gene; that is, the characteristic was recessive.
