The genetic basis of yield and its components were studied using a 9 × 9 diallel cross techniques according to Griffing’s Method 2, Model 1 in 2007. The 36 F1’s and the 9 parents were evaluated in 2 ...
Magnitude of heterosis in F2 and inbreeding depression for different quality traits of five cotton (Gossypium hirsutum) cultivars (TH-3/83, NIAB-78, CIM-109,Mc-Nair-3150 and Reshmi) in F3 generation w...
A study was undertaken to estimate the heterotic and heterobeltiotic effects in wheat during the year 2002-03 at Wheat Research Institute, AARI, Faisalabad, Pakistan to identify combinations express...
Although root system of japonica/indica F1 hybrids of rice (Oryza sativa L.) must play an important role for expression of heterosis, few studies have been conducted. This study was carried out to eva...
Vigorous growth of F1 hybrid of rice (Oryza sativa L.) may be partially attributed to the development and function of the root system, but only a few studies have been conducted in this aspect. This s...
The purpose of the present study was to collect information about the possible genetic background of glutathione peroxidase (GSHPx) activity in four pure breeds and their crosses of chickens, and its ...
The thermo-sensitive genic male sterile (TGMS) T29s line was sterile when exposed to daily mean temperatures of 24.1°C or above during the critical stage (from 15 to 11 days before heading). It was co...
Quality improvement of bacterial wilt resistant / tolerant tomato accessions was attempted by crossing with selected processing varieties. The Fl hybrids which showed the highest per se performance ...
Heterosis for yield components and fruit characters was studied using line x tester analysis between bacterial wilt resistant / tolerant accessions and processing varieties. Heterotic hybrids were i...
Eight genetically diverse high yielding rice cultivars selected from clusters formulated through Mahalanobis D2 statistics were crossed in a diallel fashion. The parents and crosses were evaluated...
An investigation involving 45 genotypes (nine parents and their diallels, excluding reciprocals) to identify the high heterotic crosses in Brassica juncea L. was undertaken during the winter seaso...
Ten elite inbred lines of ash gourd (Benincasa hispida) were selected based on their performance and were crossed in a diallel mating system (without reciprocal crosses) to generate 45 F1 hybrids. T...
In maize, three male testers and six female lines together with their 18 F1 hybrids were evaluated to study the general and specific combining ability estimates and heterosis following line x tester ...
Combining ability and heterosis were determined in a population obtained from the half diallel crossing of 6 different cotton genotypes for yield components and fiber quality parameters. For breeding...
Three F1 hybrids derived from the sterile rice lines Gang 46A, 776A and 2480A and the improved restorer line Shuhui 881 containing maize phosphoenolpyruvate carboxylase (pepc) gene were used to analyz...
