ESTIMATION OF VARIABILITY ANALYSIS PARAMETERS FOR MAJOR GROWTH AND FLOWERING TRAITS OF Lilium leichtlinii var. maximowiczii GERMPLASM

This experiment was carried out to evaluate the Lilium leichtlinii var maximowiczii germplasm collected from the different natural habitats from all over Korea. In total 30 accessions were studied for nine traits viz. plant height, leaf length, leaf width, the numbers of flowers, flower diameter, length of outer tepal, width of outer tepal, the number of leaf burn, and days to flowering in randomized block design with three replications. The ANOVA revealed highly significant variability prevailing among the investigated genotypes for almost all studied traits (except leaf width). The higher estimated value of GCV, PCV, heritability (H2), and genetic advance as percent of the mean was obtained for the number of flowers and leaf burn. The moderate to high GCV and PCV coupled with higher heritability estimates (H2) and GAM were found for plant height and flower diameter. Progeny selection would be effective as the prevalence of additive gene effect for these traits. Besides, leaf width, leaf length, length of outer tepal, the width of outer tepal, and days to flowering traits were possessed moderate to low GCV and PCV value coupled with the moderate value of heritability estimate with the low level of GAM proved to be the prevalence of non-additive genetic effect thereby indicating the necessity of alternative breeding approach for these traits improvement and breeding scheme. For the former group of traits breeding hybridization and selection would be an effective method, and primarily mean performance of these traits would be very handy for the decision of selection.

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)

Potted chrysanthemums as one of high-demand potted ornamental plants are mostly cultivated using inorganic fertilizers. The organic fertilizers use as an alternative and complementary to inorganic fertilizers on potted chrysanthemum cultivation needs to be studied further. This study aims to determine the response of inorganic and organic fertilizer to agronomic characters of three potted Chrysanthemum varieties. The research was carried out in West Sumatra AIAT’s greenhouse from October to December 2020 using split-plot design with three replications. The main plots were fertilizer treatments (control, inorganic fertilizers, Bio-urine organic fertilizers) and sub-plots consisted of three potted chrysanthemum varieties (Armita, Avanthe, and Naura). Bio-urine organic fertilizers nutrient content N, P and K. The results showed that agronomic character of plant height, leaf length, leaf width, and the number of internodes resulted from type of fertilization treatments were significantly different. The highest plant height, leaf width, and number of internodes were significantly achieved in inorganic fertilizers then followed by Bio-urine organic fertilizers and control. The highest growth for the characters of plant height, stem diameter, leaf length, leaf width, petiole length, and flower diameter were attained from Avanthe. The interaction between fertilizers types and varieties was not significantly different in all observed characters.

Potato (Solanum tuberosum L.) is one of crops which cultivated by farmers in Central Sulawesi. These potatoes are traditionally cultivated without going through the breeding process, so they have high variations. This study aims to obtain information on genetic diversity, heritability, and correlation between the characterics of potatoes from farmers in Napu who are still cultivating potato crops. Design used in this study was a randomized block design with two replications. The results showed that tuber color and harvest age had a small coefficient of genetic diversity. The heritability values of tuber color are include in the small category, Diameter of stem, number of leaves, leaf length, leaf width, leaf color, tuber length, tuber diameter, tuber weight, number of tuber and harvest age in this study are include in the high category. So that, these characteristics can be derived and selection can be made. In Napu potatoes, the number of tubers was genetically positively (medium) correlated between plant height and stem diameters, plant height with leaf width, leaf length with leaf width, leaf length with tuber diameters and tuber diameters with the number of tubers. While the positive correlation was very significant (strong) between plant height and leaf length, and very significant (strong) negative correlation between leaf color and tuber length, so can be used as a selection criteria for increasing potato crops.

Abstract Imbalanced mineral nutrition and scant information about nitrogen (N) in plants may result in reduction in sorghum morpho-physiological activities. However, farmers use higher or lower fertilizer doses regarding sorghum growth and yield. This study was undertaken to determine the response of sorghum morpho-physiological activities to different rates of nitrogen (N) during two growing seasons of 2017 and 2018. The treatments were consisted of a factorial combination of three N levels (N1 = 0 kg N ha− 1, N2 = 150 Kg N ha− 1, and N3 = 300 kg N ha− 1) and two varieties (V1 = CFSH30, and V2 = Siyong 3180). Treatments were arranged in a randomized complete block design with three replicates. Our results found that N application (N2 and N3) significantly increased plant growth and morpho-physiological activities; leaf length increased by 2.7–8.9%, leaf width by 0.4–4.5%, plant height by 27.8–20.5%, Specific leaf weight by 4.2–10.9%, leaf weight by 18.4–17.4%, and protein contents by 39.5–117.0% compared to N1. Interestingly, higher rates of N reduced number of plants m− 2 by 42.4–24.8% but increased number of plants m− 2 weight kg− 1 by 11.6–62.8%. Moreover, compared with control, N enhanced CAT activity by 92.8-131.9%, SOD by 81.2–84.5%, and POD by 43.6–52.8% in 2017 and 2018. This study indicated that N3 significantly performed best among all treatments during the two growing seasons particularly in case of V1. Moreover, we also concluded that V1 performed better in terms of producing higher leaf width, plant height, specific leaf weight, stem weight, number of plants m2 (weight/kg− 1), protein contents, and antioxidant enzymes activity as compared to V2.

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.
