Genetic diversity is prerequisite for any crop improvement program as it helps breeders in the development of superior recombinants. Th is study was conducted with the aim of evaluating genetic parameters and phenotypic divergence in a germplasm consisted of twenty rice varieties. High estimates of heritability coupled with high genetic advance found for total grains per panicle, fi lled grains...

Rice (Oryza sativa L.) inflorescence (panicle) architecture is an important agronomic trait for rice breeding. A number of high-yielding japonica rice strains, characterized by an erect panicle (EP) of their architecture, have been released as commercial varieties in China. But no EP-type indica varieties are released so far. Here, we identified two allelic erect-panicle mutants in indica rice,...

An experiment was conducted with 36 accessions of traditional (local) Boro rice germplasm accessions of three different groups (20 accessions as Kaliboro, 12 as Jagliboro and 4 as Tepiboro) during Boro season 2004 at BRRI farm to identify the duplicates with the help of morph-agronomic characters. On the basis of D values, the 36 genotypes were grouped into six clusters with a range of intra (0...

Abstract This study aims to examine the good production characteristics and path analyses as well character correlation of highland F4 new plant type lines. The research was conducted in four paddy fields, namely Bittuang, Rantebua, Sesean, Tallunglipu sub-districts at altitudes 650, 850, 1400 1600 meters above sea level North Toraja Tana Regencies. took place from June December 2021 arranged r...

Despite the ability of sorghum [Sorghum bicolor (L.) Moench] to withstand harsh environmental conditions, it is susceptible water-deficit stress during grain filling. To identify postflowering, drought-tolerant genotypes, parents nested association mapping populations were evaluated under controlled and conditions in greenhouse field conditions. In both experiments, was imposed by withholding w...

The aim of this study was to figure out genetic variability, correlation and path co-coefficients for seven traits in 42 F3 families the cross Azucena/CB 87R*1 aimed developing new restorer lines with indica tropical japonica background their utilization a hybrid program. population exhibited high PCV  GCV  viz., number productive tillers per plant, panicle weight single plant yield. ...
