TLDR
Mutation breeding was effective in creating variability and in the development of new plant genotypes that may be of agronomic value in rapeseed grown in Kenya.Abstract:
Commercial varieties of rapeseed grown in Kenya have various production constraints. Mutation breeding has been used globally to develop varieties with desirable traits. The objectives of the studi...read more

Chapter 16 – Genetic Improvement of Rapeseed Mustard through Induced Mutations
TL;DR: Using physical and chemical mutagens, a large spectrum of variability for various characteristics has been isolated in Brassica crops, resulting in the isolation of a large number of alleles for specific genes.

The Selection of Superior Genotypes with High Oil Yield Performance in Rapeseed Mutant Lines (Brassica Napus L.)
TL;DR: Stepwise regression analysis showed that number of pod per plant and per main stem, pod length on main stem and -grain weight explained the most of the variation of yield suggesting that they can be used as indices for increasing grain and oil yield in oilseed rape breeding.

Global impact of mutation-derived varieties
TL;DR: Induced mutations will continue to have an increasing role in creating crop varieties with traits such as modified oil, protein and starch quality, enhanced uptake of specific metals, deeper rooting system, and resistance to drought, diseases and salinity as a major component of the environmentally sustainable agriculture.

Morphophysiological determinants of yield in rapeseed (Brassica campestris and Brassica napus). II.* Yield components
TL;DR: The results of this experiment supported the widely held view that yield component compensation in grain crops is an inevitable consequence of a limited input of metabolites to the developing inflorescence and should, therefore, be accompanied by appropriate adjustments in the yield component system.

Relationship between genetic distance and heterosis for yield and morphological traits in winter canola (Brassica napus L.).
TL;DR: Clustering, based on yield and yield-component traits, demonstrated that inter-clusters heterosis was greater than intra-cluster heterosis in the majority of cases, and positive and highly significant for seed yield, number of pods plant-1, and number of seeds pod-1.

Identification of RAPD markers linked to linolenic acid genes in rapessed
TL;DR: Molecular techniques of gene mapping through RAPD markers were applied on a microspore-derived progeny from a high × low linolenic acid F1 hybrid confirmed that two independant mutations were implied in the low linonenic acid content.

Genetics and Cytology of a New Male-Sterile, Female-Fertile Soybean Mutant
TL;DR: The expression of the male-sterile gene is associated with rapid degenerative changes both in the tapetum and the parietal layer and is initiated at the late sporogenous mass stage.
