High heritability coupled with high genetic advance as percentage of mean were observed for plant height, no. of seed per fruit, number of fruit per plant and ascorbic acid in all the species taken under study. Path coefficient analysis revealed that the character no. of fruit per plant showed maximum positive direct effect followed by fruit weight atphenotypic level in these species. Path co-efficient analysis revealed that the character no. of fruit per plant showed maximum positive direct effect followed by fruit weight at genotypic levelin King chilli and bird’s eye chilli. Similarly path analysis revealed that the character chlorophyll contentshowed maximum positive direct effect followed by no. of fruit per plant for common chilli at genotypic level. Genetic diversity was assessed by using D2statistic for 15 genotypes of King chilli. 15 genotypes were grouped into 5 clusters. Cluster analysis for 15 genotypes revealed that cluster III i.e. genotype C-4, C-7 and C-2 were found more divergent.Genetic diversity was assessed by using D2statistic for 10 genotypes of bird’s eye chilli. Cluster analysis among 10 genotypes revealed that cluster IV with genotype C-20 was found the most divergent. Cluster analysis among 15 common chilli genotype were assessed and revealed that, Cluster II with genotype C-33, C-38,C-39, C-37, C-26,C-34 and C-29 were found more divergent. Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) showed considerable variation in protein band numbers in all the threespecies studied.The genotypes C-3 was most distantly related to C-12 in King chilli. The genotype C-23 was most distantly related to C-20 in bird’s eye chilli. C-33 was most distantly related to C-38 in common chilli.Hence, it is recommended that these genotypes could be utilized for crossing programme to create more genetic diversity. SDS-PAGE marker data provided more sub groupings and revealed higher amount of diversity as compared to morphological dataThesisItem Open Access Influence of foliar application of micronutrients on Cherry tomato [Solanum lycopersicum L. var. cerasiforme (Dunnal) A.

Highest value for yield was recorded for CHFCG-30 (344.40 g) and CHFCG-19 was observed to have earliness among all the genotypes. The high GCV and PCV (>30%) values for fruit length, fruit width, fresh weight of fruit, dry weight, fresh to dry weight ratio of fruit, number of seeds per fruit and fruit yield indicated huge genetic variability among the genotypes. High heritability accompanied with high genetic advance were observed in fruit width, fresh and dry weight of fruit, fresh to dry weight ratio, number of seeds per fruit which might be due to additive gene action. Correlation coefficient revealed that fruit yield per plant had significant positive correlation with fruit length, fruit width, fruit pedicel length, fresh weight, dry weight of fruit, number of seeds per fruit and 100 seed weight. Path coefficient analysis indicated maximum direct effect and significant positive association with fruit yield per plant through days to first fruiting, fruit length, fresh weight of fruit and number of seeds per fruit both genotypically and phenotypically. Among quantitative characters, fresh to dry weight ratio (51.60%), dry weight (21.68%), fruit width (9.24%) were the most contributing traits towards genetic diversity. Among biochemical parameters, capsanthin (52.10%) followed by ascorbic acid (19.83%), capsaicin (19.66%) contributed dominantly towards diversity. Six clusters based on quantitative traits were found wherein; Cluster V and Cluster VI had highest inter-cluster distance (13953.39). Cluster V had highest mean value for fruit yield per plant (344.40 g). Based on biochemical parameters, five clusters were recorded wherein, Cluster II and Cluster III had highest inter-cluster distance (137.93). Cluster II had highest values for TSS and ascorbic acid (5.97 0Brix, 251.95 mg/100g), Cluster IV had highest value for total chlorophyll (2.12 mg/g), Cluster V had highest value for capsaicin (2.09%), Cluster III had highest value for capsanthin (155.76 ASTA units). Overall, the genotypes exhibited abundant variability which can be exploited for further chilli crop improvement.ThesisItem Open Access Standardization of root promoters, media and NPK levels for maintenance of hybrid vigour through side shoots cutting in hybrid cherry tomato [Solanumlycopersicum L. var. cerasiforme(Dunnal) A. Gray]”(College of Horticulture and Forestry, Central Agricultural University, Pasighat -791102, 2022-09-12) M., Yogesh; Bhutia, Nangsol D; Shadap, ArwankieThe study on the influence of two factorsviz. root promoter like IBA (50 ppm, 100 ppm, 150 ppm, 200 ppm, 250 ppm and 300 ppm), NAA (50 ppm, 100 ppm, 150 ppm, 200 ppm and 250 ppm) and cow urine (25% and 50%) and rooting media [Soil + FYM (1:1), Sand+ FYM (1:1) and Cocopeat + FYM (1:1)] on rooting and survival of cuttings revealed that the root promoters significantly influenced the root parameters and survival percentage of treated side shoot cuttings. The highest number of roots (95.56), longest root (15.03 cm) and maximum fresh weight (1629.44 mg), dry weight (219.33 mg) and survival percentage (74.22%) were observed in cuttings treated with IBA 150 ppm.Among the three different media used, the maximum number of roots was observed in cocopeat + FYM (1:1) (65.18) whereasthe longest root length (10.29 cm), highest fresh weight (1373.21 mg), highest dry weight (170.23 mg) and maximum survival percentage were recorded from media soil + FYM (1:1). The combination of IBA 150 ppm with media soil + FYM (1:1) gave the maximum survival percentage (85.33%), the longest root length (20.52 cm), the highest fresh and dry weight (1690 mg and 240 mg). The effect of different levels of NPK on growth and yield of vegetatively propagated cherry tomato was observed by treating them with recommended dose of NPK fertilizers at five levels [T1 – 50% recommended dose of NPK, T2 – 75% recommended dose of NPK, T3 – 100%recommended dose of NPK, T4 – 125% recommended dose of NPK and T5 – without NPK (control)]. The treatments significantly influenced the growth, yield and quality parameters of vegetatively propagated cherry tomato. The experiment results showed that T4recorded maximum plant height (1.16 m, 2.09 m, 2.71 m and 3.11 m) at 30, 60, 90 and 120 days after transplanting respectively, and it took minimum number of days for first flowering (18.75), days to first fruit maturity (23.25) and days to first harvest (66.13). The maximum number of clusters per plant (23.25) was recorded in treatment T4. The yield parameters like number of fruits per cluster (9.75), fruit weight (12100 mg), fruit length (23.62 mm), fruit girth (22.27 mm), yield per plant (2.76 kg), yield per plot (27.6 kg) and yield per hectare (61.33 t/ha)was observed highest in treatment T4.The maximum chlorophyll A, chlorophyll B and total chlorophyll content (2.70 mg/g, 2.03 mg/g and 4.73 mg/g, respectively) was recorded in treatment T4. The quality parameters like TSS (8.79°Brix), lycopene (6.68 mg/100g) and ascorbic acid (56.04 mg/100g) were observed maximum in treatment T4. Comparisonof growth and yield of sexually propagated hybrid cherry tomato at 100% RDF with the vegetatively propagated hybrid cherry tomato recorded no significant difference with respect to yield. However, vegetative propagated plants showed early flowering, less number of days to harvest and greater number of clusters per plant compared to the seedlings. From this study, it can be concluded that propagation of hybrid cherry tomato using side shoot cuttings with IBA 150 ppm as root promoter and soil + FYM (1:1) as media with 125% of recommended dose of NPK is a viable approachThesisItem Open Access Morphological and biochemical evaluation of Faba bean (Viciafaba L.) genotypes of Manipur(College of Horticulture and Forestry, Central Agricultural University, Pasighat -791102, 2022-09-12) Lourembam, Easton; Sarma, P.; Loitongbam, BapsilaGenotypic and phenotypic coefficients of variance were found high for number of stems per plant (PCV= 40.93%, GCV= 37.13%) followed by yield per plant (PCV= 35.09%, GCV= 33.55%), vitamin C in seed (PCV= 49.07%, GCV= 48.98%), non-reducing sugar in shell (PCV= 45.19%, GCV= 43.96%).

The detail of treatments were T1 (control), T2 (100% CPE with drip irrigation), T3 (80% CPE with drip irrigation), T4 (60% CPE with drip irrigation), T5 (100% CPE with drip irrigation under mulch), T6 (80% CPE with drip irrigation under mulch), T7 (60% CPE with drip irrigation under mulch) and T8 (hand irrigation under mulch). From the present investigation it was found that the red cabbage plants irrigated at 100% CPE with drip irrigation under mulch recorded maximum growth attributes i.e. plant height (37.60 cm), plant spread (North-South and East-west) (72.93 and 72.13 cm, respectively), number of wrapper leaves (56.67) and least days to 50% head maturity (102.67). Further, the head yield and yield related attributes i.e. circumference (43.25 cm), polar diameter (14.39 cm), equatorial diameter (16.47 cm), net of weight head (1.25 kg) and yield (42.18 t/ha) were also noted higher in treatment T5. Water use efficiency (WUE) was significantly influenced by different irrigation regimes. Treatment T7 (60% CPE with drip irrigation under mulch) reported maximum WUE (5.35 t/ha mm) which was at par with T6 and T4 while treatment with full irrigation recorded minimum WUE. Drip irrigation regimes significantly influenced the quality attributes of red cabbage. Treatments with least application of irrigation water (T1) reported the highest TSS (10.27 ºB), ascorbic acid content (102.33 mg/100g), total carbohydrates (3.30 g/100g) and anthocyanin (23.66 mg/100g) content while total protein content synchronously increased with decreased levels of irrigation and the maximum total protein content (2.84 g/100g) was reported from T4 (60% CPE with drip irrigation) which was at par with T5 and T8. Thus, treatment T5 (100% CPE with drip irrigation under mulch) may be recommended for better growth and yield of red cabbage under protected condition
