“…Corm size 4 (3.2-3.5 cm) recorded the highest values of flowering and vegetative growth parameters, as well as of cormlet production (Table 2). Saffron has a globular corm with diameters ranging from 0.5 to 5.0 cm, and its weight ranges from 1 to 20 g, depending on environmental conditions and agricultural management (Ali et al, 2018;Douglas et al, 2014). Each corm can produce one to four apical shoots containing developing flower and leaf (Ali et al, 2018).…”

“…Saffron is a sterile autotriploid and stemless monocotyledonous autumnflowering geophyte plant (Ali et al, 2018;Nemati et al, 2019). Its corm survives for only one season, and it reproduces new cormlets formed above the old one during each season, which gives rise to new plants.…”

“…Therefore, daughter corms produced by mother corms are the only propagation method of saffron (Douglas et al, 2014). A mother saffron corm produces typically one to four cormlets per season through field cultivation (Ali et al, 2018;Cavusoglu and Erkel, 2005). Difficulties in its cultivation in limited farmland located at high altitudes under cold climate conditions and laborious nature of harvesting and handling (Douglas et al, 2014;Khilare et al, 2019;Kumar et al, 2008) have made saffron the most expensive spice in the world (Aytekin and Acikgoz, 2008;Winterhalter and Straubinger, 2000).…”

Hydroponics is a promising method for cultivation of saffron (Crocus sativus). In this study, saffron corms were sprouted using a gradual decrease in air temperature, and they were cultivated hydroponically in either perlite or volcanic rock for 24 weeks. A nutrient solution was supplied using either an ebb-and-flow system or continuous immersion. First blooming was observed 29 days after transplantation. Among flowering traits, only the stigma length was significantly influenced by the type of hydroponic system. Saffron plants displayed better growth parameters, a higher photosynthetic rate and stomatal conductance (gS), as well as daughter corm (cormlet) production under the continuous immersion system, in comparison with the ebb-and-flow system. Small corms (22–25 mm diameter) did not bloom, and the emergence of flowers increased with corm size. Plant growth and photosynthetic parameters, as well as cormlet production, significantly increased with corm size. We obtained the highest stigma yield [number of flowers (1.9), stigma length (39.4 mm), stigma fresh (42.8 mg), and dry weight (5.3 mg)] and cormlet yield [number of cormlets (5.7), average corm diameter (25 mm), and fresh weight (6.4 g)] using mother corms sized ≥32 mm diameter grown hydroponically in the volcanic rock–based continuous immersion system.

The present study analysed a total of 272 saffron (Crocus sativusL.) genotypes using multivariate analysis. We carefully observed and recorded information about the floral, morphological and corm attributes. Significant variations were observed among the genotypes for all the traits, indicating a high level of variability and suggesting a great potential for saffron improvement. The phenotypic variances were found to be greater than the estimated genotypic variances. Descriptive data on various morphological traits revealed significant differences in the frequency of phenotype classes as well as a wide distribution range. The high heritability estimates were observed in average number of daughter corms per plant (ANDCPP), initial weight of corms (IWC g), no. of buds/corm (NBPC), – no. of leaves in main sprout, (NLMS), number of sprouted buds per corm (NSBpC) and total number of leaves (TNL), whereas average weight of daughter corms per plant (AWBCPP), corm diameter (CDcm), pistal length (PL) cm, style length (STYLcm), fresh weight of pistals per plant (FWOPPPmg) and stigma length (STML cm), revealed medium sense of heritability. The traits dry weight of pistals per plants (DWOPPP mg), inner tepal width (ITW cm), leaf length (LLcm), number of flowers per corm (NFpC), outer tepal length (OTLcm), parianth length with tube (PLWT cm) and weight of stigma (WSTG mg) exhibited low broad-sense heritability. Principal component analysis (PCA) divulged that the first eight component characters had an eigenvalue greater than one with a contributory cumulative variance of 66.15% to the total variance, while as rest of the 16 components contributed 33.85% of total variation in a set of 272 genotypes of saffron. The eigenvalues for yield attributing traits for significant PCs ranged from 5.48 (PC1) to 1.03(PC8). The current study has revealed that there was a sufficient variability in a set of saffron germplasm lines which forms the basis for performance-based clonal selection. Moreover, identified elite genotypes based on saffron yield and corm attributes could be used in the saffron breeding programme for the development of saffron varieties.
