The D2 statistic of Mahalanobis and canonic variables coupled with the grouping methods of Tocher and nearest neighbour were used to study divergence in 7 cotton cultivars grown at Vicosa, Brazil, in 1990. The 7 cultivars were divided into 4 group...

Cotton leaf curl virus disease (CLCuD) is an important constraint to cotton production. The resistance of G. arboreum to this devastating disease is well documented. In the present investigation, we explored the possibility of transferring genes f...

Two cotton cultivars, CNPA Precoce 1 and HR102, were subjected to recurrent selection for resistance to ramulose caused by Colletotrichum gossypii var. cephalosporioides. In the second selection cycle there was a significant increase in resistance...

Since 1954 cross pollination has produced wide variability in 320F as a result of extensive commercial cultivation. Harland's method of mass pedigree selection has been used to improve the variety. From 441 plants initially screened in 1962-6...

The herbicidal endothall (7-oxabicyclo 2.2.1 heptane-2,3-dicarboxylic acid) was applied to cotton cotyledon discs. Treatment with 10-4 M endothall for 24 h resulted in injury which was expressed by increased leakage of electrolytes, development of...

Host-plant resistance is the most economic and effective strategy for root-knot nematode (RKN) Meloidogyne incognita control in cotton (Gossypium hirsutum L.). Molecular markers linked to resistance are important for incorporating resistance genes...

Gossypium hirsutum L. is the predominant cotton of commerce and all cultivars of this species are susceptible to the reniform nematode, Rotylenchulus reniformis. To introgress resistance to R. reniformis into the tetraploid 2(AD1) G. hirsutum, a r...
