Ten genotypes of maize collected from National Center for Genetic Resources and Biotechnology (NACGRAB) were induced with X-ray for morphological and molecular assessment. The experimental design was complete randomized design with four replicates. Morphological and molecular statistical analyses of treated genotypes were conducted using SAS and Power Maker Packages, respectively while dendrogram was generated using Jaccards similarity coefficient using Unweighted Paired Group Method and Arithmetic Averages (UPGMA). The study revealed significant difference which is an indication of genetic variation of characters in treated maize. Genotype DTSR-Wco performed best in plant height (62.35 cm), leaf length (62.35 cm), number of leaves (3.15), leaf width (7.55 cm) and dry leaf biomass (0.24 g). X-ray at 90 Kv/mass, 95 Kv/mass and 100 Kv/mass decreased plant heights to 54.25cm, 53.87cm and 54.10cm respectively compared to Control. Heritability estimate was greater than 70% for all characters evaluated. Genotype TZM 1551 at 0 Kv/mass yielded the highest concentration of DNA at 2841.60 ng/ul and the highest genomic DNA concentration was obtained at 95 Kv/mass for TZM 132 with 1.91%. Primer BMC 1755 was most polymorphic with 58.77% in treated maize genotypes. The plant height was strongly correlated with leaf length (r=0.9), leaf width (r=0.76) and number of leaves (r=0.77). Principal component analysis showed close relationship between plant height (-0.03) and leaf length (0.05) compared with leaf width (-0.67) and number of leaves (0.69). Dry shoot biomass (0.05) was closely related to dry root biomass (-0.03) and dry leaf biomass (-0.04).

The study assessed the genetic diversity of pearl millet accessions grown in Nigeria and India based on morpho-agronomic traits in order to identify genotypes with superior characters which could be utilized in breeding programmes. Twenty-four pearl millet accessions were grown and evaluated for agronomic and morphological traits during the dry and wet seasons of 2015-2016. Data collected on the accessions using standard descriptors were analysed statistically. IP22281 had the highest mean plant height (108.90 cm) while NGB00531 recorded the lowest (61.02 cm). Significant intra-specific variation existed in number of leaves per plant, leaf length, leaf width, number of nodes and internode length, however, stem girth was similar for the accessions. Tillering was generally poor with the highest value (1.60 tillers per plant) found in NGB00531. A significant positive correlation occurred between plant height, number of leaves, leaf length and leaf width. Panicles emerged between 44 and 56 days and NGB00548 had the shortest maturity time. Also, panicle length and peduncle diameter varied significantly for the accessions. The highest grain yield and 1000-grain weight were recorded in NGB00616 and the lowest yield and weight were recorded in IP22269. The principal component analysis grouped the accessions into four clusters, comprising mixtures of Nigerian and Indian members. Similarly, the dendrogram grouped the accessions into two main groups which were sub-divided into smaller clusters with accessions from Nigeria and India in the same cluster. The study concludes that variations in morpho-agronomic and yield characters among the accessions studied could be harnessed for crop improvement. The clustering pattern of these accessions indicated their genetic relatedness, possibly from the same progenitor, but separation by geographical or ecological isolation mechanisms.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Fritillaria meleagris is an endangered Eurasian species with declining populations in most of its distribution area. The signifi cance of the present study is to provide details for improving methods, how age-state structure can be identifi ed in a population. This could help finding the appropriate way of site-management where this species occurs. We investigated two F. meleagris populations in the western part of Hungary (Gyékényes, Tüskeszentpéter). We grouped the recorded plants into five age-state categories: dormant, juvenile, subadult, vegetative- and reproductive adult. We investigated diff erent plant traits such as plant height, number of leaves, leaf width and leaf length. The relative frequencies of leaf numbers differed signifi cantly between the two sites each year. Generally, the majority of the flowering plants had 5-6 leaves at both sites. Only plant height was positively related to plant reproductive success, but there were no clear trends in leaf width and leaf length. There are considerable diff erences in age-state ratios between our sampling sites. The proportion of reproductive plants was noticeably higher in both years in Tüskeszentpéter. Transition into dormant state was regular from all age groups at both sites.

This study uses a single Randomized Complete Design (CRD) method consisting of 10 treatments that are repeated 3 times, consisting of K0, K1, K2, K3, K4, K5, K6, K7, K8, K9, the results of this study were analyzed with Duncan's Multiple Range Test (DMRT) at 5%, the parameters observed were: plant height, number of leaves, leaf width, leaf length, root length, fresh weightof biomass, and dry weight of biomass. The results of the study show that: (1) Giving treatment (K3), liquid organic fertilizer of banana peels with a concentration of 150 ml/l, provides interaction with parameters of observation of leaf width, root length and dry weight of biomass arugula plants, but they need to increase the concentration of organic fertilizer liquid to assist the growth process with observations of plant height parameters, number of leaves, leaf length and fresh weigh of biomass. (2) Provision of treatment with 150 ml/l concentration is the best treatment for the parameters of observation of leaf width, length of root and dry weight of biomass, but the administration of 150 ml/l concentration is not sufficient for plant nutrient requirements so there is no interaction with the growth process of plant height, number of leaves, length of leaves and fresh weight of biomass. (3) The highest dry weight of biomass in the treatment of liquid organic fertilizer from banana peel waste with a concentration of 150 ml/l, weighing 4.32 g or an increase of 20% compared to the control.

Kale and catfish are the most popular vegetables and fish in Indonesia. The production of these two commodities can be done using an aquaponics system. This study aims to determine the growth of water spinach plants and the survival of catfish in the aquaponic system. Plant growth parameters were measured every three days which included plant height, leaf width, leaf length, number of leaves and plant weight after harvest. The development of catfish that was observed every three days included the number of dead catfish and the weight of catfish measured every nine days. The data obtained were then tabulated and processed in graphical form and analyzed descriptively. The results showed The growth rate of kale planted in the aquaponic system includes plant height, leaf length, and leaf width, respectively, 2.51 cm / three days, 0.75 cm / three days and 0.24 cm / three days, while in kale plants (control) 1.30 / three days, 0.5 cm / three days, and 0.12 cm / three days, respectively. The yield of water spinach planted with the aquaponics system weighed 350 grams / pot, while the control water spinach was only 135 grams / pot. During 30 days of maintenance there was an increase in weight of catfish as much as 11.25 grams / head with the survival rate (SR) of catfish seeds by 93%.

Ginger (Zingiber officinale Roscoe) is an important medicinal crop grown for its aromatic rhizome which is used as a spice, food, flavouring agent and medicine. It has been characterised for its hypoglycemic, hypotensive, antioxidant and antibiotic properties. This study was conducted to determine the impact of plant growth-promoting potential of bacterial strain Bacillus subtilis L2 on plant growth and physiological properties of ginger. The experiment was carried out in randomised block design with three replications in pot experiments. The plants were grown in greenhouse conditions for three months. The results showed that at 8 and 12 weeks after planting (WAP) bacterial inoculation increased plant height, leaf length, number of leaves per plant and leaf width. Inoculation with B. subtilis L2 significantly increased plant height by 16, 20 and 18% compared to control at 4, 8 and 12 WAP. At 8 and 12 WAP, leaf length significantly raised by B. subtilis L2 as compared to uninoculated control. B. subtilis L2 significantly increased the number of leaves per plant and leaf width by 30 and 21% respectively when comparing with non-inoculated plants at 8 WAP. The percentage increase in chlorophyll content resulted from the inoculation with B. subtilis L2 over the control was 10.5%, 15.5% and 18.4% at 4, 8 and 12 WAP respectively. It is concluded that there is a significant positive effect of inoculation with B. subtilis L2 on the growth of ginger. B. subtilis L2 strain can be used as a potential agent or bio-fertiliser for stimulation of ginger growth.
