Lint yields of Arkot 1202 from replicated field tests at four sites in Arkansas over five years were greater than lint yields of UA222 and ‘UA48’ (check cultivar) at each location, except equal at Rohwer. Over all locations, lint yields of Arkot 1202 were 9.9% and 23.5% greater than UA222 and UA48, respectively. Soils at all sites are silt loams, except the Sharkey clay at Keiser. Compared to UA222, Arkot 1202 produced higher lint index (8.1 vs. 7.7 g), seed index (11.4 vs. 11.1 g), fibers per seed (16883 vs. 16273), plant height (103 vs. 93 cm), open boll percentage (59 vs. 51%), quality score (72 vs. 58), fiber length (32.8 vs. 31.9 mm), and fiber uniformity index (86.1 vs. 85.6%); equal lint fraction (41.2 vs. 42.3%), seed ha-1 (18236 × 1000 vs. 17665 × 1000), S-score (77 vs. 70), fiber density (159 vs. 157 fibers mm-2 of seed coat) and short fiber content (6.0 vs. 6.1%); and lower micronaire (4.33 vs. 4.41), fiber strength (315 vs. 321 kN m kg-1), fiber elongation (5.3 vs. 7.8%), leaf pubescence rating (2.6 vs. 4.9), stem pubescence (3.6 vs. 5.1 rating), and marginal bract trichome density (32 vs. 38 trichomes cm-1). Arkot 1202 is resistance to all U.S. races of Xanthomonas citri ssp. malvacearum (ex Smith 1901) Schaad et al. 2007, the causal agent of bacterial blight. Damaged flowers for Arkot 1202 (67%) was lower than the susceptible check (95%), equal to UA48 (66%) and higher than UA222 (54%) in tests of resistance to tarnished plant bug [Lygus lineolaris (Palisot de Beauvois)]. Resistance to seed deterioration of Arkot 1202 was better than UA222 and equal to UA48. | 2142981 | PI 702793 |
