Central Agricultural University, Pasighat

The Central Agricultural University has been established by an act of Parliament, the Central Agricultural University Act, 1992 (No.40 of 1992). The Act came into effect on 26th January, 1993 with the issue of notification by the Department of Agricultural Research and Education (DARE), Govt. of India. The University became functional with the joining of first Vice-Chancellor on 13th September, 1993. The jurisdiction of the University extends to six North-Eastern Hill States viz., Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Sikkim and Tripura, with headquarters at Imphal in Manipur. College of Horticulture & Forestry, a constituent College of the Central Agricultural University, Imphal, Manipur, was established on 7th March 2001 at Pasighat, Arunachal Pradesh on the bank of beautiful river Siang.

    Evaluation of genetic variability, correlation and path coefficients analysis for yield attributing traits in field pea [Pisum sativum (L.) var. arvense]
    (Res. on Crops 18 (2) : 316-321 (2017), 2017-06-30) Singh, BRIJESH KUMAR; Res. on Crops 18 (2) : 316-321 (2017); SUTRADHAR, MONOJ
    An experiment was conducted in randomized complete block with 12 field pea genotypes to study the genotypic and phenotypic coefficients of variation, heritability, genetic advance, correlation among the yield contributing traits and their effect on number of seeds per pod of field pea. The phenotypic correlation coefficient (PCV) values were marginally bigger than genotypic correlation coefficient (GCV), revealing tiny sway of environment in character expression. High heritability coupled with high genetic advance and high GCV were observed for length of branch from main axis, number of seeds/plant and weight of 100 seeds indicating the multitude of additive gene action. Selection stranded on these characters will be worthwhile. Results of genotypic and phenotypic correlation coefficients showed significant positive correlation of stem circumference, number of seeds/ plant, number of pods/plant, weight of 100 seeds, number of seeds/pod with each other and other yield attributes. The component characters and path-coefficient analysis revealed positive direct effect of plant height at maturity and number of leaves/plant on the number of seeds/pod. The analysis suggests that the above mentioned parameters were sufficient for direct selection of genotypes for yield attributing characters. However, the high residual effect and relatively moderate level of genetic parameters revealed the requirement of more number of yield attributing parameters under consideration for improvising in crop breeding pipeline of field pea.

    Studies on seed protein profiling in chilli (Capsicum annuum L) genotypes of Northeast India
    (Australian Journal of Crop Science, 2014-12-31) Yatung, Tasso
    North eastern region of India exhibits wide variability in fruit morphology, pungency, bearing habit and crop duration of chilli. In the present study, thirty chilli (Capsicum annuum L) genotypes from different areas of North eastern hill and other part of India were collected and evaluated for genetic diversity using morphological characters and SDS-PAGE analysis. Estimation of protein was done in seeds of thirty genotypes of chilli collected for the study. The analysis showed considerable variation in banding pattern of total protein which ranged from 7-19 numbers of bands. On the basis of presence (+) or absence (-) of bands, similarity index was calculated and genotypes were grouped in three major clusters which were further sub divided in 9 sub-clusters. The genotype CHFC9 was most distantly related to CHFC18. Hence, it was recommended that genotype CHFC9 and CHFC18 could be utilised for crossing programme to create more genetic diversity or segregants of desired characteristics through chilli breeding programmes. Hence, overview of diversity of chilli genotypes from North eastern hill region of India paves the way for conservation and utilization of genotypes and contributes to the development of systematic breeding programme.
