Heterobeltiosis for Yield and Salinity Tolerance in Desi Cotton (G. herbaceum L.) Hybrids
Publication Date : 29/07/2016
The present investigation was carried out to study the performance and heterobeltiosis of desi cotton (G. herbaceum L.) hybrids in saline soils of Gujarat. Analysis of variances revealed significant differences among crosses for all the 22 characters which indicated the presence of substantial amount of genetic variability among the hybrids. Seven hybrids registered significant and positive heterobeltiosis, and high heterobeltiosis in these hybrids was generally associated with their good per se performance. Top three crosses with significant positive heterobeltiosis were G. Cot. 23 x GShv 433/08 (49.12 %), Digvijay x GBhv 293 (41.35 %) and Digvijay x GShv 280/11 (30.09 %). Hybrids exhibiting high heterobeltiosis for seed cotton yield per plant also had high heterobeltiosis for yield contributing characters and physiological parameters.
