ROLE OF THE ENVIRONMENT IN PLANT BREEDING

Environment affects selection and progress from selection. The genetic gain or response to

selection is the difference between the mean phenotypic value of selected offspring from parental population and that of the parental population before selection. Response to selection is used to compare selection methods and to predict environments.

INTRODUCTION TO QUANTITATIVE GENETICS Part - 1

PART- I

In the body of any organism there are two types of characters i.e. qualitative and quantitative .The characters which are governed by one or few genes are called oligogenic or qualitative character and those which are governed by numerous genes are called polygenic or quantitative character.

Cell is the basic unit that organizes a body. It is defined as “the structural, functional and hereditary unit of life.”

Effect of chemical mutagens

Effect of chemical mutagens

Chemical mutagens affect the organisms at molecular level. Action of chemical mutagens may or may not give beneficial result. It can change the sequence of nucleotides or may replace the nitrogenous bases in DNA. On the basis of effect of chemical mutagens (at molecular level), it is classified into following categories. We have to understand the molecular basis of to know its effect.

INTRODUCTION TO GROUNDNUT IN RESPECT OF VARIABILITY AND GENETIC PARAMETER FOR QUALITY CHARACTER

                                                                                                               INTRODUCTION 

 

                Groundnut (Arachis hypogaea L.) is a self pollinated, allotetraploid (2n=4x=40) with a genome size of 2891 Mbp. Groundnut (Arachis hypogaea L.), a major oilseed crop that ranks 12th position among the food crops of the world. This annual legume is a native of South America (Brazil), but now grown throughout the tropical and warm
