Polyploidy induction in Trigonella foenum-graecum L morphological and chemical comparison between diploids and induced autotetraploids cultivars

Trigonella foenum graecum L is a diploid leguminous plant (2n = 16) used as forage and vegetable The objective of this study was to produce a polyploid cultivar of this plant and to evaluate its morphological and chemical potentialities Polyploidy induction was carried out by using a 0 5% colchicine solution Tetraploids and diploids seeds resulting from the obtained mixoploids and the control seeds were used for the comparative study extended on 4 plant generations The autotetraploid cultivar has larger leaf area and larger productivity compared to the diploids concerning seed number, pod number and branch number Its leaves are richer in potassium, sodium, calcium and phosphorus Polyploidy induction is an effective method to increase the yield and the mineral contents of Trigonella foenum-graecum
