10. Assessment of the agro-morphological variations in bread wheat genotypes under field conditions
Main Article Content
Abstract
The agro-morphological traits of seven bread wheat genotypes were assessed 4 genotypes were collected from International Wheat and Maize Improvement Centre Mexico, 2 from Nuclear Institute of Agriculture Tandojam, and 1 from Wheat Research Institute Sakrand, based on (RBCD) with 3 replications. The results indicated the number of grains/spikes were 41.29-70.29 grains with mean 54.02±4.42 and 0.20 coefficient variance. The grain yield/spikes were 1.88-3.54 grams with mean 2.75±0.23 at 0.21 coefficient variance with grain yield/plant were 5.05-20.51 grams with mean of 12.24±2.38 were obtained. The maximum 14.02 grams, grain yield/plant were recorded in ESWYT-104 and 14.20 grams in ESWYT-123, while minimum 8.44 grams in SKD-1 genotype. The maximum plant height was 97.66 centimeters in ESWYT-104 and minimum 77 centimeters in SKD-1. The ESWYT-136 produced maximum 66.33 while; genotype SKD-1 minimum of 40.33 grains/spike. The grains/spike showed positive with significant correlation in grain yield/spike 0.97 days for maturity and plant height 0.91. The grain yield/meter with positively non-significant correlation in grain yield/spike 0.16, grain yield/plant 0.00, and 100-grain weight 0.07. The plant height with negative, non-significant correlation to peduncle length -0.00, the number of tillers/meter -0.00, ten grains length -0.71, and harvest index -0.42. The analysis of variance showed significant and highly significant variations for agro-morphological traits in booting, flowering, heading, awns length, maturity, number of grains/spike, grain yield/spike, grain yield/meter, peduncle length, and ten grains length. Among these genotypes, ESWYT-136, ESWYT-104, and ESWYT-123 were observed beneficial for yield-related traits and are recommended for future cultivation breeding perspectives.
