Mutation breeding, evolution, and the law of recurrent variation

In the present paper the history of the rise and fall of mutation breeding as an autonomous branch of breeding research is documented as well as its positive side effects for plant breeding and biology in general. Perhaps the most important generalization on the basis of the total outcome of mutation breeding will be termed “the law of recurrent variation”. It states that “treating homozygous l...

In Vivo and in Vitro Mutation Breeding of Citrus

Spontaneous mutations are important for the development of new Citrus varieties, but these mutations appear at a low frequency in nature. In contrast, induced mutagenesis using radiation or chemical mutagens can increase the rate of mutation many fold, which increases the genetic variability that is available for selection. However, few induced mutants have been officially released for cultivat...

Biofertilizers in Fruit Crops - a Review

BiofertiJizers are microbial preparations containing living cells of different microorganisms which have the ability to mobilize plant nutrients in soil from unusable to usable form through biological process. They are environmental friendly and play significant role in crop production. Previollsly it is mainly used for field crops but now-a-days it is used for fruit crops also. Biofertilizers ...

Role of bacterial biofertilizers in agriculture and forestry

Many rhizospheric bacterial strains possess plant growth-promoting mechanisms. These bacteria can be applied as biofertilizers in agriculture and forestry, enhancing crop yields. Bacterial biofertilizers can improve plant growth through several different mechanisms: (i) the synthesis of plant nutrients or phytohormones, which can be absorbed by plants, (ii) the mobilization of soil compounds, m...
