Evaluation of germplasm lines for seed yield traits in Job's tears (Coix lacryma jobi L)

Abstract

Job's tears (Coix lacryma jobi L), a lesser known and old crop is superior to major crops like wheat, maize, rice etc in terms of nutritive values. Moreover the crop shows considerable genetic diversity which can be exploited for productive and sustainable use. Very little information is available about the crop. Present study was conducted to compare various seed yield traits of various germplasm lines of the crop at Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during 2020–21. The days to maturity of plants range was between 102 (IGJT 20-2) and 162 days (IGJT 20–28).Average plant height varied from 92 (IGJT-2) to 168 cm (IGJT 20–23). The highest number of tillers per plant (15) was in IGJT 20–22 and the lowest (3) in IGJT 20–19. Average seed yield per plant was in the range of 11 (IGJT 20–29) and 95 g (IGJT 20–16).
