Yield traits

Rice (Oryza sativa L.) is one of the staple cereal crops of the world and it is one of the main sources of carbohydrates for nearly one-half of the world's population. So, an increase in rice yield to satisfy human needs is a pressing requirement. Agronomic characters such as high plant, length of panicle, length of flag leaf, number of seed per panicle, the weight of thousand rice, length and width of rice and tolerance to salt are the deciding factor for yield in rice.

Twenty one genotypes including check Krishna were evaluated in randomized block design with three replications during kharif-2017 at research farm of TCA, Dholi for estimation of genetic variability among them. Genotypes varied significantly for all the morpho-physiological characters indicating the presence of considerable variability among the genotypes. Significant bidirectional shift was observed in the mean values as compared to better check, thus provided scope for selection.

The prime objective of any plant breeder is developing new cultivars with high yield. The present investigation aimed at estimating the general combining ability among parents and specific combining ability in hybrids for various yield and related traits in upland cotton. Forty hybrids were obtained by crossing 8 elite lines with 5 selected testers in a Line × Tester fashion.

The present investigation was under taken with the objectives to estimate genetic variability, heritability and genetic advance for yield and yield contributing components of cucumber. The experimental materials for this investigation were fourteen genotypes of cucumber consisting of parthenocarpic, gynoecious and monecious germplasms crossed in line × tester mating design produced thirty three hybrids (F1). Thirty three F1 crosses along with their parents were evaluated in two environments viz.

The estimates of genotypic correlation coefficients in general were higher than their corresponding phenotypic correlation coefficients indicating strong inherent association among the traits. The seed yield per plant had significant and positive association with number of primary branches plant-1, number of secondary branches plant-1 , number of pods plant-1 , number of seeds plant-1 , biological yield plant-1 , seed yield (kg/ha) harvest index and 100-seed weight at both genotypic as well as phenotypic levels.

Upland rice grows on 19 million ha, about 15% of the world's rice plantation [2]. The production of upland rice is crucial to agricultural economy of many countries [15]. The yield of upland rice is very low with an average of about 1 t/ha. Drought is a major constraint to the productivity of upland rice.

Understanding the genetic complexity of traits is an important objective of small grain temperate cereals yield and adaptation improvements. Bi-parental quantitative trait loci (QTL) linkage mapping is a powerful method to identify genetic regions that co-segregate in the trait of interest within the research population. However, recently, association or linkage disequilibrium (LD) mapping using a genome-wide association study (GWAS) became an approach for unraveling the molecular genetic basis underlying the natural phenotypic variation.
