Incognita, and has good productivity and fiber quality. In 1998 and 1999 was compared to Stoneville 474 in field evaluations conducted in reniform nematode-infested and fumigated (1,3-dichloropropene) plots at Weslaco, TX. In 1998, produced significantly greater yields than Stoneville 474 in both the reniform nematode-infested and fumigated plots. Lint yield reduction caused by reniform nematodes was less than 50% of that observed for Stoneville 474. Reniform nematode population level (log reniform nematode population/100 g soil) was significantly lower than for Stoneville 474. Yield reduction due to nematodes was 17% less than Stoneville 474. In 1999, yield in untreated plots was 98% of Stoneville 474. In 2000 at Weslaco, TX, RN96425 and Deltapine 50 were compared in reniform nematode-infested field plots. Lint yield was 45% higher than Deltapine 50. In environmental growth chamber experiments repeated 2 yrs. at College Station, TX, the root-knot nematode root gall index averaged 1.6 compared to 3.8 for the standard susceptible check, Deltapine 16; in 1998, only 3% as many root-knot nematode eggs were produced on RN96425 as on Deltapine 16. In Fusuarium Wilt Root Knot Nematode Evaluations at Bossier City, LA, during 1998 and 1999, root-knot nematode gall ratings averaged 1.4 compared to 3.6 for Stoneville 474; average fusarium wilt rating was 1.4 compared to 3.6 for Stoneville 474. At Regional Cotton Fusarium Wilt Nursery, Tallassee, AL, during 1999 and 2002, average wilt incidence was 5% compared to 44% for Rowden, the susceptible check and 2% for M-315, the resistant check. Compared to Stoneville 474, lint percentage was 2.5% lower, micronaire value was 1.4 units lower and fiber was 19% stronger. | 1663310 | PI 636102 |
