Genetic variation and correlation studies in maize testcrosses under the agro climatic condition of Nowshera
Abstract
In order toassess the genetic variation in maize via S1 testcross (121genotypes), a tri-replicated experiment was conducted at Cereal Crops Research Institute (CCRI) Pirsabak, Nowshera in randomized complete block (RCBD) design. The experiments were conducted in two seasons.Analysis of variance revealed that all the tested hybrids were significantly different for all the studied traits. The data for days to 50% tasseling, days to 50% silking, plant height, ear height, ear diameter, ear length, fresh ear weight, number of kernel row ear-1, 100-grain weight and grain yield (metric tons hac-1) ranged from 46 to 53 days, 47.66 to 54.66 days, 131.66to 198 cm, 95.33 to 58.33 cm, 3.75 to 4.79 cm, 12.72 to 17.19 cm, 2.19 to 5.78 kg, 10.53 to 15.60 rows ear-1, 26.06 to 39.53g and 4.35 to 12.68 (metric tons hac-1) respectively. Analysis of correlation revealed that yield was highly significant and positively associated with plant height, ear height, ear diameter, ear length, fresh ear weight, 100-grain weight, while non-significant and positive correlation was found with number of kernel rows ear-1. The negative and non-significant association of grain yield was founded with days to 50% tasseling, days to 50% silking. The promising hybrid for number of kernels rows ear-1was “TC49” while TC-26 and TC-49 showed minimum days to 50% tasseling and silking and could be released as early maturing hybrids.
