The present investigation was aimed at ascertaining the nature and magnitude of genetic diversity among a set of 12 lentil genotypes through Mahalanobis D2 Method. The genotypes under study fall into four clusters. The cluster-I contained the highest number of genotypes (05) followed by cluster-III (03) and Cluster-II and IV each contained the lowest (02). Cluster-II produced the highest mean value for days to maturity and cluster-I exhibited minimum mean value for pod length (0.64). The inter-cluster distances were much higher than the intra-cluster distances. Members of cluster -III and IV were highly diverse from each other as these clusters showed maximum inter-cluster distance. Cluster-IV exhibited the highest intra-cluster distance while the lowest distance was observed in cluster-I. The highest inter-cluster distance was observed between cluster-III and IV while the lowest was between cluster-I and III. The trait pod length (33.33%) contributed maximum for genetic diversity followed by seed yield /plant (27.27%), 100 seed weight (21.21%) and days to maturity (10.61%). Therefore these characters contributed maximum for getting the genetic diversity.

Genetic diversity of seventeen chickpea genotypes was studied through Mahalanobis D2, Tocher’s Method. The genotypes under study fall into five clusters. The cluster- IInd contained the highest number of genotypes (08) and Cluster IV and V contained the lowest (01). Cluster- II produced the highest mean value for days to maturity. The inter-cluster distances were much higher than the intra-cluster distances. Cluster-V exhibited the highest intra-cluster distance while the lowest distance was observed in cluster-IV and V. The highest inter-cluster distance was observed between cluster-III and V while the lowest was between cluster-I and IV. Considering all the characters, it is suggested that the genotypes 81-0-800, C-306, 96907, C-235 and SCS-3 could be used as parents for future breeding programmes to develop high yielding varieties of chickpea. As per AMMI model, two genotypes i.e. C-81 and 96911 were identified as having wider adaptability along with higher seed yield per plant.

Genetic divergence among 22 genotypes of lentil was estimated using D2 and principal component analysis. The genotypes under study fell into four clusters. The intra-cluster value was the maximum in cluster I and the minimum in cluster II. The inter-cluster distance was larger than the intra-cluster distance in all the cases suggesting the wider genetic diversity among the genotypes of different groups. The inter-cluster value indicated maximum distance between cluster I and II than cluster III and IV. Thus the genetically diverged genotypes of the clusters could be used as parent in hybridization program to get desirable genotypes. Cluster I had the highest mean for days to maturity, plant height, pods/plant and per plot yield while cluster II and III had the highest days to first flowering and 100 seed weight, respectively. Genotypes with these characters in respective groups would, therefore, offer a good scope of improvement of lentil through selection.   Key words: Lentil; cluster analysis; divergence; hybridization DOI: http://dx.doi.org/10.3329/bjpbg.v23i1.9312 BJPBG 2010; 23(1): 9-12

Forty genotypes of chickpea were evaluated for assessing genetic divergence for different quantitative characters for improving yield potential of chickpea by using Mahalanobis D2 statistics. The genotypes were grouped into seven clusters suggesting considerable amount of genetic diversity in the material. The intra-cluster D2 value ranged from 0.00 to 9.06 while, intercluster D2 value ranged from 4.07 to 55.71. The maximum intra cluster distance was exhibited by cluster V followed by cluster II and cluster I. Cluster III had mono- genotype and emerged with contained highest cluster mean value grain yield per plot. Cluster II has highest mean value for number of pods per plant and lowest mean value for days to 50% flowering, days to maturity and plant height. Maximum contribution toward the total divergence was exhibited by 100-seed weight followed by number of pods per plant and minimum by days to maturity. Cluster IV and VI showing maximum inter cluster distance and crossing of genotypes Sabour chana-1 (BRC-1), GCP 105, PBC 503, DC 16-2, NBeG 776, RVSSG 42, G2016-43, GL 14042, IPC 2013-21, GNG 2338, GNG 2375 and KWR 108 from cluster VI suggested for improving grain yield per plot, 100-seed weight and earliness in flowering and ultimately enhancing the yield and chances of getting better recombinants in segregating generations.

The present study entitled “Genetic diversity Studies in Field Pea Germplasm (Pisum sativum var. arvense L.)” was carried out to estimate the genetic variability for yield and yield contributing traits, study the relationship between yield and yield attributing traits on seed yield and its component traits and to assess direct and indirect of yield attributing traits on seed yield. The experimental material was consisting of 41 Field Pea genotypes. The experiment was laid out in Randomized complete block design with three replications. The observations were recorded on five randomly selected plants from each treatment and replication for 12 different quantitative traits Days to 50% flowering, Days to 50% pod setting, Plant height (cm), Number of branches per plant, Number of Pods per plant, Number of seeds per pod, Pod length (cm) days to maturity, biological yield (gm), Harvest Index, Seed Index (gm), Seed yield per plant (gm). Based on the mean performance, high seed yield per plant were identified for the genotype zimndal (11.59) followed by Matar-23 (10.76). The higher phenotypic and genotypic coefficient of variations were observed for number of primary branches per plant (33.92 & 24.56), seed yield per plant (29.84 & 25.67) and number of seeds per pod (28.61 & 22.64). High heritability coupled with high genetic advance as percent of mean was observed for plant height (84.43 & 40.55), days to 50% flowering (77.30 & 34.92) and pod length (71.55 & 32.55). Based on Mahalanobis D2 values 41 genotypes grouped into 8 clusters. Among 8 clusters cluster I had more number of genotypes (25) followed by cluster II (8 genotypes), cluster VIII (3 genotypes). The maximum intra cluster distance was observed in cluster VIII (10.26) followed by cluster II (8.59) and cluster I (7.72). The highest inter cluster distance observed between cluster I and cluster VI (24.07) followed by cluster I and cluster IV (22.25), cluster I and cluster III (21.41). Therefore, genotypes present in these clusters may be used as parents to produce the transgressive segregants. The cluster IV (12.57) had significant and higher cluster mean for seed yield per plant. The trait number of primary branches per plant (25.12%) had maximum contribution towards to genetic divergence followed by harvest index (21.95%), biological yield per plant (19.39%), seed yield per plant (19.15%).

Genetic diversity study was conducted in 38 chickpea (Cicer arietinum L.) genotypes using Mahalanobis D2 Statistics. The current research performed at FoA, Wadura Sopore, SKUAST-Kashmir in the rabi 2017-18. In the present study, total seven clusters have been formed and range of D2 values is from 301.78 to 8477.71, cluster II includes maximum 12 genotypes after that cluster I having 9 genotypes, cluster IV having 6 genotypes, cluster Ⅲ and Ⅴ having 4 genotypes, cluster Ⅵ having 2 genotypes and cluster Ⅶ with 1 genotype. 959.33 to 8477.71 is the range of inter cluster distance. Highest inter cluster distance (8477.71) was found between the clusters, Ⅵ and Ⅶ followed by the clusters, Ⅳ and Ⅶ (5814.62), Ⅳ and Ⅴ (5807.441), Ⅴ and Ⅵ (4659.34). The minimum inter-cluster distance (959.33) possessed by clusters, Ⅱ and Ⅲ. After comprehending the intra cluster divergence it has been found that cluster Ⅳ has highest intra cluster distance (637.07) then cluster I (459.16). Since cluster Ⅶ includes only one genotype which indicates that there is no intra cluster divergence. Total nine traits have been evaluated, plant height registered higher divergence (49.25%) then pods plant-1 (36.12%), days to 50% flowering (4.13%) and days to maturity (2.7%), secondary branches plant-1 (3.24%), seed yield plant-1 (1.28%) and primary branches plant-1 (1.14%). The 100-seed weight (1.12%) and seeds pod-1 (1.02%) possesses less divergence. By considering above results the nine genotypes viz., IR-1, IR-3, IR-30, IR-20, IR-21, IR-10, IR-2, IR-7 and IR-31 have been recognized as desired genotypes for use in future breeding programme.

Diversity Study

Genetic diversity among 30 chickpea genotypes was assessed for yield attributing and traits related to mechanical harvesting during rabi 2016-17 under both rainfed and irrigated conditions as separate experiments. The genotypes were grown in randomized block design (RBD) with three replications. Genetic diversity study grouped 30 chickpea genotypes into five different clusters under both the tested environments. Days to 50 per cent flowering followed by days to maturity and 100 seed weight contributed maximum towards diversity under rainfed as well as irrigated conditions. Inter cluster average D2 values stretched between 7.42 and 20.11 under rain fed condition, while it was slightly higher and varied from 8.64 to 28 under irrigated condition. The most divergent clusters were IV and V under both the situations. The traits that are suitable for mechanical harvesting particularly, height of the first pod and plant height contributed more (8.3 per cent and 8.1 per cent respectively) towards the genetic divergence under irrigated than under rainfed condition (3 per cent and 5.5 per cent respectively). While the angle of the primary branch couldn’t show any influence on the divergence under both the tested environments. Promising genotypes with suitable traits for mechanical harvesting besides having yield advantage are‘NBeG 780’, ‘NBeG 857’, ‘NBeG 47’, ‘NBeG 863’ and ‘BG 3061’ of cluster I under rainfed and cluster II under irrigated, ‘GBM 2’ of cluster II in rainfed and cluster I in irrigated, ‘ICCL 85213’ and ‘NBeG 865’ of cluster III under rainfed, ‘DBGV 3104’ of cluster I under rainfed and ‘GL 12021’ of cluster V under both rainfed and irrigated are suggested for utilization in the crossing programs to breed varieties of chickpea for high yield with amenability to combine harvesting.

Thirty eight genotypes were subjected to genetic divergence by using D2 statistics. The genotypes were grouped into 7 clusters by D2 analysis. Cluster I consisted of maximum accessions (32) followed by cluster II, III IV, V, VI, VII consisted of only 1 accession. The inter-cluster distances were greater than intra-cluster distances, revealing that considerable amount of genetic diversity existed among the accessions. Maximum intra cluster distance was observed in cluster I (56.58) indicating that some genetic divergence still existed among the genotypes. This could be made use of in the yield improvement through recombination breeding. Highest mean values exhibited no. of seeds per plant in cluster II (198.97), days to maturity in cluster VII (93.11), harvest index in cluster V (76.15) and plant height in cluster IV (69.59). The character contribution maximum towards diversity among the accessions were seed yield per plant (18.40%), followed by harvest index (14.32%), biological yield (11.98%), no. of pods per plant (10.76%), pod length (9.80%) and no. of seeds per plant (7.56%). These characters combining with early maturity were the major traits causing genetic divergence among the accessions. It was assumed that maximum mount of heterosis will be manifested in cross combinations involving the parents belonging to most divergent clusters.
