ED were found for NLRS as compared with other genotypes (r = 0.
At both sites, consistently high and low yields were found for the late maturing conventional P3905 and NLRS genotypes, respectively.
Abbreviations: ED, ear diameter; EL, ear length; GY, grain yield; HI, harvest index; KNR, kernel number per row; KRN, kernel row number; LNS, leafy normal stature; LRS, leafy reduced stature; NLNS, nonleafy normal stature; NLRS, nonleafy reduced-stature; P3905, Pioneer 3905; P3979, Pioneer 3979; RUE, radiation use efficiency; SDM, stover dry mass.
Effects of plant density on internode length, ear height, above-ear leaf number, and above-ear leaf area in the NLRS, LRS, LNS and NLNS genotypes.
Internode length Ear height Low High Low High Genotype density density density density -- cm -- NLRS 7.
No differences were found between the low and the high plant population densities for NLRS above-ear leaf numbers and aboveear leaf areas, probably because the single NLRS is smaller than the other lines, has fewer leaves, and requires less solar energy to reach maturity than the other lines examined.
There were no effects on these variables for NLRS or LRS genotypes.
Effect of plant density on corn heat units from planting to tasselling, corn heat units from planting to silking, number of days between tasselling and silking, single plant grain yield and grain yield in the NLRS, LRS, LNS, and NLNS genotypes.
