“…with a minimum temperature of 28.30-33.30 °C and relative humidity of 81.00-87.00 per cent. This is in conformity with the studies of Negi et al (2020) [26] and Nozaki and Fukai (2008) [27] in chrysanthemum. Different varieties of chrysanthemum exhibited significant variation for plant spread (E-W) (Table 2).…”

A field experiment was carried out to study the performance of chrysanthemum genotypes which suitable for cultivation in different seasons (Kharif, rabi and summer). The experiment was laid out in Randomized Block Design with fifty new genotypes in two replications at college of horticulture, Bengaluru. Based on the evaluation of various vegetative and yield parameters, the results revealed that plant height was found highest in cv. Cream white (55.32 cm) and HCC-1 (50.46 cm) and minimum was found in cv. Arka Pink Star (24.12 cm). Highest number of primary and secondary branches was found in cv. Poornima Yellow (17.37) and NBRI Little Pink (30.30). Maximum East-West and North-South direction plant spread was obtained in cv. Ruby Red (47.82 cm) and cv. IIHR RC-1 (44.91 cm). Number of flowers per plant was found highest in cv. Cream White (183.50) whereas, minimum was found in NBRI Little Orange (112.73). Maximum flower yield per plant was obtained in Scent White (424.56 g) followed by Poornima White (403.50 g), Aishwarya-1 (389.03 g) and Cream White (389.71 g).

Germplasm characterization is essential to estimate variation and identify desirable genotypes for crop improvement. The current study was conducted on eight qualitative and 14 quantitative traits related to growth and floral attributes for characterization and grouping of 54 chrysanthemum genotypes. Wide variability was observed among most of the traits and principal component analysis revealed that the first two principal components explained most of the existing variation (>98%) in germplasm. Genotypic coefficient of variation exhibited a wide range from 9.41% (ratio of leaf length/width) to 105.99% (corolla tube length of ray florets), while phenotypic coefficient of variation varied from 10.49% (ratio of leaf length/width) to 106.38% (corolla tube length of ray florets). Broad sense heritability estimates were higher (>96%) for most of the characters, except for traits such as ratio of leaf length/width and peduncle thickness. Forty-four pair-wise inter-trait combinations showed positive genotypic and phenotypic correlations for 91 possible combinations. D2 analysis revealed that genotypes of clusters I and IV to be highly distinct, and hybridization between them might have better chance to obtain desirable types. D2 analysis confirmed that the cultivars in cluster IV namely, Red D Spoon, Tokyo Soldier, Yellow Reflex and hierarchical clustering showed that the cultivar Tokyo Soldier to be highly diverse. It is recommended to use the above genotypes in crossing programme for obtaining better progenies.
