Abstract A study was conducted to characterize four phenotypes (black, white with black tips, light brown and dark brown) of naked neck chickens [n=320; 80(40♂, 40♀)] for qualitative and quantitative traits at 20 weeks of age. Qualitative phenotypic characterization was based on head appearance, comb type, wattle size, plumage pattern, shank color, spurs prevalence and number of toes. Quantitative phenotypic characterization was based on neck length, keel length, shank length, drum stick length, body length, wing span and circumference. Males and females of all phenotype had plain head and single comb. Plain feather pattern was predominantly most frequent on breast, wing bow, wing bar, wing bay, saddle and tail followed by stippled, penciled and laced. Males had most frequent yellow shanks followed by grey, off-white and green. White black, light and dark brown phenotypes expressed maximum yellow shank coloration whereas grey shanks were most frequent in black birds. Morpho-metric measurements were significantly higher in males than females. Light and dark brown phenotypes had higher values of quantitative traits than those of black and white black. All males and females of naked neck phenotypes possessed four toes, normal spurs and tuft feathers on the ventral portion of the neck above crop. The phenotypic variation observed in indigenous naked neck chickens could provide valuable basic information to develop effective utilization and conservation programs.

The Phenotypic characteristics of three genotypes of native chicken comprising of Non-descript Desi (ND), Hilly (H) and Naked Neck (NN) were studied. A total of 180 individual chickens (Male: ND= 20; H= 20 and NN=20; Female: ND= 40, H=40 and NN = 40) were characterized under intensive management system for qualitative and quantitative traits. The results indicated that the predominant plumage color of three types of native chickens was black brownish (33.33%) followed by white with black tips (28.33 %) and red brownish (18.33%). Values indicate that 35% of native chickens had whitish shank color followed by yellowish 31.68%; black 11.66 % and others 21.67 %. All hens of ND, H and NN laid light brown (62.42%) to cream or off white (30.28%) colored eggs. Variations were also found on quantitative traits such as shank length, body weight and reproductive traits on intensive management system. number of eggs/ hen from starting to ten months of laying were 108, 104 and 112, respectively in ND, H and NN genotypes. Three native chicken genotypes showed distinct physical variations for both qualitative and quantitative traits under intensive management system.

Using Data

Morpho-agronomic characters consist of two types of qualitative and quantitative characters. Qualitative characters were discontinuous and score data form, while the quantitative are continuous and measurable. Kinship analysis is important for breeders to know the genetic distance between genotypes. Allegedly there are differences in the genetic kinship analysis between based on data from qualitative to quantitative character. The aim of this study was to compare the results of the analysis of kinship based on quantitative and qualitative data on phenotypic characterization of local rice. A total of 43 local rice from West Java was used on phenotypic characterization activities. The research was done at Sukamandi experiment station of ICRR (Indonesian Rice Research Institute) on 2014. Qualitative characters were observed as many as 24 characters, and quantitative as many as 23 characters. Analysis of data was by using Minitab version 14. The results indicate that kinship analysis results using data from qualitative, quantitative or a combination of both was not significantly different at the component level analysis of the number of clusters and similarity but there were real differences in the level of genetic distance. Dendogram based on qualitative characters was different than based on quantitative character. Analysis of kinship between genotype recommended using a data combination of qualitative and quantitative character that the genetic distance between genotype information more accurately

Raden I, Nugroho CC. Syahrani. 2017. Identification and characterization of morphological diversity of Lemba (Curculigo latifolia) in East Kalimantan, Indonesia. Biodiversitas 18: 1367-1376. Lemba (Curculigo latifolia) is Kalimantan’s land prospective for commercial cultivation because its leaf fiber has been traditionally utilized as fiber source for ulap doyo woven cloth; its fruit as sweetener; and its root as medicinal herb. To this days, only a few of research has been conducted on lemba in East Kalimantan or even in Indonesia, including studies on lemba plant phenotype suitable for weaving material. Thus, a research about identification and morphological characterization of lemba cultivars is necessary to identify and characterize lemba plant in East Kalimantan to reveal phenotypic variability in both quantitative and qualitative traits that can be utilized as the source of germplasm for the plant breeding program. This study was carried out in three Sub-districts, i.e.: Tenggarong Sub-district (Kutai Kartanegara District), Kota Bangun Subdistrict (Kutai Kartanegara District), and Jempang Sub-district (West Kutai District). Data collection was done by observation, and measurement of quantitative and qualitative traits of lemba plant. Descriptive analysis was applied on the morphological traits data, while correlation analysis was performed to reveal relationship between the qualitative and quantitative morphological traits by using software Minitab v.14.12. Phenotypic variability was determined based on the standard deviation. Principal component analysis and cluster analysis of the data were performed by using software SPSS v.11.6. The variance value of the 33 observed lemba plant accessions from the three Sub-districts indicated that the phenotypic variability of the qualitative traits was narrow while that of the quantitative traits was broad. There are three principal components that account for the observed variability with a cumulative variance of 96% which is obtained from 19 observed traits. Cluster analysis at similarity 95% indicates that there are five lemba accessions groups based on only qualitative, only quantitative, or based on combined qualitative and quantitative traits.

The purpose of this study was to estimate the genetic divergence in sweet cassava accessions by molecular markers and quantitative and qualitative characters, as well as determine the correlation between these estimates. Sixteen sweet cassava accessions of the Regional Cassava Germplasm Bank of the Cerrado were evaluated under field conditions, for 13 quantitative and 33 qualitative characters. In the laboratory, the accessions were evaluated with RAPD markers. Subsequently, matrixes of genetic dissimilarity/distance among the accessions were estimated based on molecular markers and quantitative and qualitative characters. Besides, the significance of the correlation between the matrixes was estimated. The RAPD, qualitative and quantitative data indicated the existence of high divergence among the accessions. The divergences estimated by molecular markers and by quantitative traits were weakly associated with each other and moderately with the divergence estimated by qualitative characters.

Abstract. This study was conducted to characterize local chickens in the northwest of Algeria based on some phenotypic traits and to look at prediction of body weight from morphometric measurements (linear body). The results indicated that the predominant comb colour was dark red (77.8 %), followed by light red (22.2 %). Tarsus colour was either white (40.9 %), grey (31 %), yellow (15.39 %), dark (8.05 %), or green (4.51 %). Most chickens (81.7 %) had orange eyes, while 10.37 and 7.92 % had yellow and dark-brown eyes, respectively. The dominant earlobe colour was white (73.96 %), followed by red (16.81 %). The remaining proportion included yellow and red-mottled yellow and black earlobes. Proportions of the adaptive genes were low. Incidences of Na, F, Pti, Cr, R, and P genes were 8.82, 0.45, 1.22, 5.54, 3.35, and 4.7 %, respectively. The calculated gene frequencies ranged from 0.002 to 0.045. Variations were also found in quantitative morphological traits. Sex-associated differences (P < 0.001) were observed in almost all the parameters evaluated with higher values recorded for males. Phenotypic correlations of body weight and biometric traits ranged from −0.13 to 0.88 and −0.15 to 0.97 for males and females, respectively. From the factor analysis with varimax rotation of the intercorrelated traits, three principal components which accounted for 71.6 and 73.2 % of the total variance were extracted in males and females, respectively. Orthogonal body shape characters derived from the factor analysis accounted for 84.3 and 94.2 % of the variation in body weight of males and females, respectively. Information obtained from this study could be useful in an appropriate management, breeding programmes for selection and utilization of Algerian chicken genetic resources.

The physical characteristics of 338 indigenous helmeted guinea fowls at 28 and 52 weeks of age were described. Four main colour types or varieties recognised were Ash (Lavender), Black, Pearl (Grey) and pure White. Body weights averaged 1.15 ± 0.03kg and 1.34 ± 0.05kg at 28 and 52 weeks of age respectively for the guinea cocks and 1.07 æ 0.04kg and 1.29 æ 0.06kg at 28 and 52 weeks respectively for the guinea hens. The overall mean body weight for the entire population was 1.1 ± 0.4kg at 28 weeks of age and 1.31 ± 0.07kg at 52 weeks of age. Body weights were significantly (P<.05) bigger at end of laying (52 weeks) than at pointof lay. The males at each age and in each variety also had larger body weights than the females. The guinea cocks had slightly longer body (43.1 vs 42.6cm), keel (14.8 vs 14.4cm), wing (20.3 vs 20.2cm), shank (8.4 vs 7.9cm), drum stick (13.1vs 12.4cm), thigh (9.9 vs 9.6cm), toes and claws, wattle (3.0 vs 2.6cm), jhelmet (3.7 vs 3.2cm), beak (2.7 vs 2.5cm) and larger body girth (30.3 vs 29.4cm) than the guinea hens. About 21.14 and 24.16% of the neck of the males and females respectively were devoid of feathers. Colour of the naked portion of the neck was bluish-black and bear long hair like filoplumes on the dorsalregion. The colour of the beak was light brown in all the birds. All the Black and White birds had light brown shanks while 28.9 and 37.5% of the Ash and Pearl birds, respectively had partly brown and partly grey shank. 62.5 and 28.6% of the Pearl and Ash birds respectively, had brown shanks while 42.6% of the Ash birds had grey shank. The colour of the wattle was red in all the birds. The great variation in the various parameters measured and weighed suggests that they can probably be used in selection and hence genetic improvement of the local helmeted guinea fowl.

Background: The characterization of chickpea genetic resources is a vital step to explore genetic variability in breeding programs. In the present study, we characterized 90 germplasm lines of desi chickpea collected across the Indian chickpea growing region. The identified trait-specific germplasm lines will be used as a valuable genetic resource for the chickpea improvement programme. Methods: An experiment was conducted in augmented design to characterize germplasm lines of chickpea for 13 qualitative and 17 quantitative agro-morphological traits under Bundelkhand agro-climatic conditions. Result: Ample variation was observed for qualitative and quantitative traits. The study revealed that the presences of high variability in qualitative and quantitative traits are useful in the identification of plant genotype for a specific trait, genetic purity analysis, germplasm conservation and also possible use of potential genotype in the breeding program.
