Effect of outcrossing on quality characteristics in Indian mustard (Brassica juncea L.)

Published on

Indian mustard (Brassica juncea L.) is an important
oilseed crop covering about 80% of the rapeseedmustard cropped area in the country. This crop is largely
self-pollinated. Nevertheless, out crossing ranging from
11-24 % has earlier been reported in this crop [1-2],
which necessitates growing the crop at an isolation
distance of at least 100m for breeder seed and
foundation seed and 50m for certified seed for
maintaining genetic purity [3]. Quality of oil is determined
by fatty acid profiles and glucosinolates content
characterizes the quality of seed meal. Chauhan et al.
[4] reported quality characteristics of 96 rapeseedmustard varieties grown in India on the basis of breeder
seed obtained from the concerned breeder/institute and
concluded that except Pusa Karishma of Indian mustard
(Brassica juncea), GSC-5, TERI (00) R 9903 and TERI
(0) R 03 of Gobhi sarson (Brassica napus), the rest
possessed high erucic, low oleic and high glucosinolates
contents. Since, outcrossing deteriorates the genetic
purity of the crop, consequently the oil and seed meal
quality would also be affected. Information on such
aspect is scanty in this crop. In the present investigation
quality characteristics of breeder and open pollinated
seeds of 25 varieties of Indian mustard were studied
over three cropping seasons to obtain precise
information on effect of out crossing on oil, protein and
glucosinolates content and fatty acid profile.
