Identifying genotype-phenotype links and causative genes from quantitative trait loci (QTL) is challenging for complex agronomically important traits. To accelerate maize gene discovery and breeding, we present the Complete-diallel design plus Unbalanced Breeding-like Inter-Cross (CUBIC) population, consisting of 1404 individuals created by extensively inter-crossing 24 widely used Chinese maize founders.

Genetic improvement of root system architecture is a promising approach for improved uptake of water and mineral nutrients distributed unevenly in the soil. To identify genomic regions associated with the length of different root types in rice, we quantified root system architecture in a set of 26 chromosome segment substitution lines derived from a cross between lowland indica rice, IR64, and upland tropical japonica rice, Kinandang Patong, (IK-CSSLs), using 2D & 3D root phenotyping platforms.

Five lines and ten testers were crossed in line x tester design to produce 50 cross combinations in order to identify the high yielding and early flowering post rainy sorghum hybrids. Promising hybrids were sorted out based on positive significant standard heterosis for grain yield along with negative significant standard heterosis for days to maturity.

In the present study, an attempt has been made to identify genetically divergent promising lines and their F1 progenies, so as to select the potential parents for breeding programme to attain the anticipated improvement in fruit yield per plant of sponge gourd either by crossing two dissimilar parents to get heterotic F1 or by making single cross, three way cross, double cross and selfing of crosses (F1) obtained by the divergent parents of sponge gourd.

The present investigation entitled “Diallel Analysis in Cowpea (Vigna unguiculata (L.) Walp.)” was conducted during kharif, 2013.Seven diverse cowpea parents were selected and crossed in half diallel fashion in order to determine heterosis to identify promising hybrids for eleven traits including yield and its components.

In the present study, an overall appraisal of GCA effects revealed that RH0735 and BPR349-9 in normal environment and RH0116 and RH0555A in late sown environment were good general combiner for majority of the characters. High GCA effects are related to additive gene effects or additive x additive interaction which represent the fixable genetic component of variation. Hence these parents could be efficiently used for exploiting seed yield.

Currently available rice varieties contain low percent of protein and many deficiency symptoms are predominantly seen in rice eating population are observed. To improve the efficiency of breeding for total grain protein in rice, a thorough understanding of the genetics of the trait concerned is essential. In order to address this problem we have identified promising local indica rice, (HPR14), which possesses relatively higher protein than cultivated rice. The rice protein normally posses 7-8 percent while the donor genotype identified has an average of 14.1 percent total protein.

The present study was carried out on heterosis for fruit yield and yield related traits in sponge gourd. Fifteen hybrids of sponge gourd were developed using six parents in half diallel fashion were studied for estimation of heterosis for 10 yield contributing traits. Hybrids PSG-82 × PSG-07-04, PSG-07-04 × PSG-161 and PSG-07-04 × PSG-199 were found most promising for earliness and yield. These hybrids exhibited heterosis to the tune of 59.36, 48.45 and 43.85 per cent over their better parents and 81.58, 69.16 and 63.

9 diverse barley genotypes were selected and crossed in a diallel (without reciprocals) mating design to evaluate combining ability effects to identify promising crosses for 13 quantitative characters including yield and its components. Analysis of variance for diallel revealed highly significant differences for most of the traits investigated. Parent BH 393 has been excellent general combiner for majority of traits viz., days to 50 per cent heading, days to 75 per cent maturity.

The present investigation entitled “Genetic analysis of F1 hybrids in brinjal (Solanum melongena L.)” was carried out at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Eleven genotypes (Aruna, Bhandara local, Wadsa local, Bhatai local, Manjarigota, Chandur local, Ruchira, Krishna Kathi, White Round, DBSR-52, White Brinjal) were crossed in line x tester mating design during kharif 2013.

Tomato grown during the main season (winter) causes a glut of produce in the market and its sale price is also very low. But the crop grown in rainy season has a better demand and is much remunerative for the farmer. Therefore, the present experiment was undertaken to develop and identify tomato hybrids well adapted to the rainy season. The experiment was conducted at the All India Co-ordinated Research Project on Vegetable Crops, Orissa University of Agriculture and Technology, Bhubaneswar.

The present study aimed to estimate the general and specific combining ability variances and their effects, and extent of heterobeltiosis and economic heterosis for different quantitative characters in yellow sarson. Line × Tester analysis including 11 local germplasm lines and four testers illustrated the preponderance sca over gca for all the traits studied. Based on desirable GCA effects, PYSC-11-3, PYSC-11-36, PYSC-11-44 and PYSC-11-46 among lines and B-9 among testers were identified as promising donars for seed yield.

Combining ability analysis, using Line x Tester mating design was conducted in safflower to select best material for further breeding programme and generation advancement on the basis of general and specific combining ability of the divergent parents and their crosses, respectively. Two CMS lines as female parents, 20 male parents and 40 crosses along with three checks (PKV PINK, AKS 207 and PBNS 12) were evaluated in Randomized Complete Block Design for seed yield under aphid infestation, Aphid Infestation Index (AII), total phenol and chlorophyll content.

Present investigation was carried out to study combining ability along with inheritance of grain yield and its component traits in 50 hybrids of pearl millet which were generated through line x tester mating design using 5 male sterile lines and 10 restorers as parental material at ICRISAT, Hyderabad during Summer, 2018. These hybrids were evaluated in randomized block design with 3 replications in 3 environments during Kharif, 2018 at Agricultural Research Station, Bikaner. In results, both GCA and SCA variances were found significant for majority of characters.

Diversification of parental base in any hybrid breeding programme is an important step to sustain the crop. Fifty seven uniform and stable gene pool materials and exotic collection of economic importance of sunflower were crossed with six cytoplasmic male sterile lines of PET-1 background in a Line x Tester fashion to study their maintainer or restorer reaction in a randomized block design in two replications. The inbredGP6-990 acted as restores for all six CMS lines.

Such theories do not simply have the cross-sectional implication that small ¯rms' risk will be more strongly a®ected by tighter credit markets in all eco- nomic states. Based on the idea that a decline in a borrower's net worth raises the agency cost on external ¯nance, the theories identify asymmetries in the e®ect of tighter credit market conditions on risk during recessions and expansions.
