Population growth and the high demand for food production has caused environmental degradation losses in biodiversity. The conservation of genetic resources is the most appropriate strategy for maintaining the variability of species of great importance, such as Capsicum. In this study, we describe the characterization of 69 pepper accessions of four Capsicum species from different regions of Brazil on the basis of qualitative and quantitative descriptors and ISSR markers. The 11 quantitative descriptors grouped the 69 populations into five clades. The fruit traits had the greater discrimination power. A strong correlation was detected between some pairs of quantitative descriptors: petiole and fruit length, fruit diameter and fresh fruit mass, leaf length and leaf width, canopy and plant height, stem diameter and plant height, stem diameter and canopy diameter. A negative correlation was also observed between plant height and pericarp thickness. Moreover, the molecular analysis grouped accessions into five clades. The morpho-agronomic and molecular characterization were efficient to estimate the genetic diversity between accessions, being important tools for the knowledge and use of accessions. This study is of great importance to preserve pepper germplasm and to provide data to facilitate the process of the selection in breeding programs.

This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: < 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha-1 and 326 t ha-1, respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil.

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)

Impatiens balsamina L. is a plant that is widely cultivated in Bali. The flower of this plant is used as a component of offering in Hindu religious ceremonies. The flower petals are thin and wilt easily, therefore genetic modification is needed to get better quality. This research aimed to study the effect of 0.01% colchicine with soaking periods of 4 hours, 8 hours, 12 hours and 24 hours to seedlings of I. balsamina. Seeds of I. balsamina were germinated and sprouted seeds were treated with 0.01% colchicine for 4 hours, 8 hours, 12 hours and 24 hours. The sprouted seeds were then transfer to polybag with soil media. The experiment was designed with randomized blok design with five replicates. Observations were done on plant height, length and width of leaf, stem diameter, number of stomata as well as observation on plant stem cortex cells. Results showed that colchicine reduced plant height at three weeks after planting, while plant stem diameter increased. Control plants had the smallest leaf length and width. The number of stomata decreased at plants derived from colchicine treated sprouted seeds and the lowest stomatal number observed was at soaking duration of 24 hours.
