Abstract

In order to investigate quantitative traits of MUNGBEAN [Vigna radiata (L.) Wilczk] GENOTYPEs, a field experiment was carried out in 1999 in the experimental Field station of the College of Agriculture, University of Shahid Chamran Ahvaz. This experiment was arranged as factorial-using randomized complete block design (RCBD) with four replications. Treatments included plant spacing at four levels of 15, 20, 25 and 30 cm on row (densities 133333, 100000, 80000 and 66666 plants/ha, respectivly) and three GENOTYPEs i.e. Partow, VC–1973A and 1-62-32. During the growing season, six samplings were harvested from plots and the total dry weight, leaf dry weight and leaf area were measured. At physiological maturity, GRAIN YIELD was also measured. The results showed that among the three GENOTYPEs,1-62-32 was the best, and produced the highest GRAIN YIELD (1723 Kg/ha). Growth parameters and indices including total dry weight (TDW), leaf dry weight (LDW), leaf area index (LAI), crop growth rate (CGR) and relative growth rate (RGR) were also measured. Among the three GENOTYPEs, VC-1973A and Partow had the lowest and highest SPECIFIC LEAF AREA (SLA) respectively. In this experiment Partow had the lowest GRAIN YIELD (1439 Kg/ha). The highest (1713 kg/ha) and lowest (1379 kg/ha) GRAIN YIELD obtained in plant spaces 20 and 30 cm on row, respectively. Increasing plant spacing on row increased seed yield per plant. Decreasing plant spacing on row increased TDW, LDW, LAI, CGR and SLA, however, RGR and NAR decreased. Considering the importance of SLA in increasing GRAIN YIELD, it can be concluded that increasing GRAIN YIELD in VC-19738 GENOTYPE was due to less SLA, therefore, it is recommended that SLA to be used as a selection criteria in MUNGBEAN breeding programs.
