Genetic Divergence Analysis in Indian mustard (Brassica juncea L.)

Assessment of genetic variation within Indian mustard (Brassica juncea L.) germplasm using RAPD markers

ASSESSING APHID INFESTATION IN INDIAN MUSTARD (Brassica juncea L.) UNDER PRESENT AND FUTURE CLIMATE SCENARIOS

Mustard (Brassica juncea L.) production in India suffers from aphid, Lipaphis erysimi (Kaltenbach), infestation considerably. Role of weather on the incidence and development of mustard aphids was assessed from experimental data from six north Indian locations. Aphid appearance and population build up was found to be regulated by temperature and time to attain peak population was relatively sho...

Growth response modulation by putrescine in Indian mustard Brassica juncea L. under multiple stress.

Plants, in general, are put to various kinds of stress, biotic and abiotic, both natural and manmade. Infestation by insect pests and diseases, and extreme conditions such as salinity, temperature, etc., as well as heavy metal contamination affect their growth performance. Here, we studied the impact of salinity and heavy metal pollution on the growth performance of Indian Mustard Brassica junc...

GENERATION MEAN ANALYSIS OF WATER STRESS TOLERANCE PARAMETERS IN INDIAN MUSTARD [ Brassica juncea (L.) Czern & Coss] CROSSES

Little information is available on the genetics of physiological traits for drought tolerance in Indian mustard. Generation mean analysis was performed using two crosses (Maya x BPR543-2) and (BPR543-2 x BPR2) to study the nature and magnitude of gene effects on seed yield and physiological characters in Indian mustard. The F1, F2, BC1 and BC2 of these crosses, along with P1 and P2, were studie...

An analysis of genetic variation and divergence in Indian tropical polyvoltine silkworm (Bombyx mori L.) genotypes

The genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. The results revealed that the single shell weight showed higher genetic variation such as PCV% (17.20%), GCV% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. The D2 (Mahalonobis? distance) statistics reveal...
