Description
Seed fertility and yield of male sterile Italian ryegrass (Lolium multiflorum Lam.) crossed with tall fescue (Festuca arundinacea Schreb,) varied from 2.8 to 100% and from 0.04 to 9.45 g, respectively. Significant positive correlations were found between seed fertility and seed yield per plant and between seed fertility and Pl percentage of the harvested seed, Spike type and plant type were very similar to those of tall fescue. By contrast, more than SO% of Pl plants tillered In the second crop were unlike tall fescue; however, persistency of the Pl was similar to that of tall fescue. In the second crop, the percentage of acid detergent fibre of Pl was 3% lower and the percentage of enzyme soluble dry matter was 4.3% higher than those of parental tall fescue. The percentage of voluntary intake by cattle of the third crop of Pl was much higher than that of parental tall fescue.
