Colchicines Induced Polyploid Plants and Their Identification in Three Species of Lagerstroemia indica

Abstract: The effects of colchicine concentration and treatment time duration on the apical meristems of the seedlings in three species of Lagerstroemia indica have been conducted in this study,and the ploidy level was identified by morphological trait,chromosome number and flow cytometry techniques.The results showed that treated L.indica or L.indica var.alba with 0.5%-0.8% colchicine for 48-96 h lead to a high mutation rate,and the highest mutation rate(up to 54.17%)was achieved in the L.indica by treatment of 0.5% colchicine for 72 h.All the three tested species of L.indica have obtained a number of tetraploidy plants.The choromosome number of mutated plants was 2n=4x=96,while that of the control plants was 2n=2x=48.The tetraploid plants exibited some morphological and cytological variations,including larger and thicker leaves,darker leaf color,larger stomata,fewer stomata per unit area,more chloroplasts in stomata guard cell and longer pollen diameter.The ornamental value of single flower had also been greatly improved by increasing of flower diameter,petals and basal claw length.

MORPHOLOGICAL CHARACTERIZATION AND GENETIC DIVERSITY IN LENTIL (Lens culinaris Medikus ssp. culinaris) GERMPLASM

Abstract: Genetic divergence of 110 lentil germplasm with checks was assessed based on morphological traits using multivariate analysis. Mahalanobis generalized distance (D2) analysis was used to group the lentil genotypes. Significant variations among lentil genotypes were observed in respect of days to 1st flowering, days to 50% flowering, days to maturity, plant height, and number of pods per peduncle, number of pods per plant, number of seeds per plant, 100 seed weight and yield per plant. Considering the mean values, the germplasm were grouped into ten clusters. The highest number of genotypes (17) was in cluster X and lowest (5) both in cluster II and IV. Cluster IV had the highest cluster mean for number of pods per plant (297.08), number of seeds per plant (594.16), 100 seed weight (1.44 g) and yield per plant (8.53 g). Among them, the highest inter-cluster distance was obtained between the cluster IV and I (24.61) followed by IV and III (22.33), while the lowest was between IX and II (1.63). The maximum value of inter-cluster distance indicated that genotypes belonging to cluster IV were far diverged from those of cluster I. The first female flower initiation was earlier in BD-3812 (49 days) in cluster I and cluster IV had highest grain yield per plant (8.53). BD-3807 produced significant maximum number of pods per plant (298.40) in cluster IV. DOI: http://dx.doi.org/10.3329/ijarit.v4i1.21095 Int. J. Agril. Res. Innov. & Tech. 4 (1): 70-76, June, 2014
