Table 2 Quantitative characters studied from nine parents and their crosses.
Quantitative trait | Abbreviation (unit) | Description of evaluation method |
|---|---|---|
Plant height | PH (cm) | Plant height was measured from the base to the tip of the main shoot of 10 randomly selected plants in meter scale at the time of harvest (pre-bud stage, 90 DAS) |
Base diameter | BD (mm) | Average base diameter of 10 randomly selected plants was measured at the base of the stem in mm using slide calipers |
Core diameter | CD (mm) | It was measured at the base point of the stem using slide calipers after the fiber separated from the stem. It was taken at the end of retting period |
Middle diameter | MD (mm) | It was measured at the mid-point between base and top of the stem using slide calipers. It was also taken at the time of harvest |
Top diameter | TD (mm) | It was measured at the top of the stem using slide calipers. It was also taken at the time of harvest |
Number of nodes | NN | Number of nodes of 10 randomly selected plants was counted and averaged then for getting node no/plant |
Days to first flowering | DTFF (days) | It was recorded as the number of days from the date of sowing to beginning of flowering in the population of each genotype |
Days to 50% flowering | D50%F (days) | The number of days to flowering was quantified from planting date to the day when 50% flowering in the population of each genotype |
Fresh stem weight with leaves and pods | FW1 (g) | Average fresh stem weight with leaves and pods of 10 plants was recorded using electric balance just after harvest and then per plant basis weight was calculated |
Fresh stem weight without leaves and pods | FW2 (g) | Fresh stem weight of 10 randomly selected plants without leaves and pods was taken using electric balance just after harvest and then per plant basis weight was calculated |
Dry stick weight | DSW (g) | It was measured from 10 previously selected plants after extraction of fiber and proper sun drying of the stick and the mean was computed |
Dry fiber weight | DFW (g) | Dry fiber weight of randomly selected 10 plants from each plot was taken after retting and proper drying in the sun. Finally, per plant basis weight was calculated |
Number of pods per plant | NF | Number of total pods from first to last pod setting per plant was counted in the field and recorded |
Number of seeds per pod | NS | Number of matured seeds from 30 randomly selected pods per replication was counted and it was then averaged and replication wise recorded |
1000 seeds weight | SW (g) | Weight of 1000 dry seeds (10% moisture) of each genotype for each replication was measured using digital balance and recorded |
