Correlation with grain yield
-
Breeding for high yield crops require information on nature and magnitude of variation in the available material, relationship of yield with other agronomic characters and the degree of environmental influence on the expression of these component characters. Since grain yield in rice is quantitative in nature and polygenically controlled, effective yield improvement and simultaneous improvement of yield components are imperative.

Analysis of variance indicated the existence of significant differences among the progenies for all the traits. Correlation co-efficients among grain yield and its fourteen attributing traits were estimated in two hundred F3 population of rice. The study revealed significant positive correlation of number of filled grains per panicle, spikelet fertility, total number grains per panicle, number of productive tillers per plant and 1000-grain weight with grain yield.

Information on correlation of yield and its component attributes and their direct and indirect effects on grain yield are of paramount significance. Correlation in combination with path analysis would give a better insight into cause and effect relationship between different pairs of characters. It is also helpful to study the correlation in genome wide association mapping to deep insights the linkage, direction and magnitude of each and every traits of grain yield and its components traits.

The genetic nature of character association for various traits was studied in Rabi sorghum using F2 populations derived from four crosses of M 35-1 with specialty varieties viz., AKJ-1 (flaking), KMJ - 1 (popping), and SMJ-1 & RSJ-1 (hurda purpose). These varieties derived from landraces are recommended for cultivation in Northern Dry Zone of Karnataka.

The exploitation of yield potential through inter sub specific (inter-racial) hybridization become a challenging task for rice breeders. Grain yield improvement is considered to be prime objective of any breeding programme, quality traits are yet another important consideration of rice breeding in India. Association of yield and yield components and among grain quality traits thus assumes a unique prominence as the basis for selecting desirable high yielding genotypes with good grain quality characters.

Correlation and path analysis was carried out at Agricultural Research Station, Tamil Nadu Agricultural University, Paramakudi to study the association between eight yield related traits during Rabi 2019-20 in 37 rice genotypes under rainfed rice ecosystem. Days to 50% flowering, number of panicles per square metre, number of filled grains per panicle and straw yield expressed positive and significant correlation with grain yield.

A field experiment was conducted in kharif 2011on blackgram genotype T-9. The experiment was laid out in randomized block design with three replication and thirteen treatments. There was significant improvement recorded in yield, nutrient content, uptake and physico-chemical properties viz. pH, electrical conductivity, organic carbon and available N and P of soil under black gram crop. Grain yield was increased by 47.06% in treatment T13 over control while, organic carbon showed significantly highly positive correlation with available nitrogen (r=.878) in post harvest soil.

Thirteen rabi sorghum genotypes were studied for root traits in rabi 2013-14 at All India Sorghum Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri in Phule Root Box Structure under receding soil moisture. The genotypes were sown on exclusively receding soil moisture under rainout shelter. The results of soil moisture status revealed that the soil moisture gradually decreased from sowing till the harvest of crop. The moisture depletion was less at vegetative phase as compared to reproductive phase. The sharp decrease with increasing depth was observed at reproductive phase.

What is an important food crop in India but of the entire world. The study indicates that the analysis of the variance showed highly significant differences for all the characters. Genetic variability indicated that high estimates of GCV and PCV were observed for the traits like 1000 grain weight, grains per spike, spikelets per spike, spike length and yield per plot. Further, high heritability coupled with high genetic advance as percent of mean was also observed, indicating the less influence of environmental variance in these characters.

The study was conducted to determine the correlation and path coefficients among the yield and yield component characters in 14 parental lines and 91 hybrids of pearl millet (Pennisetum glaucum L. R. Br), formulated by a diallel cross excluding reciprocals. Strong and significant genotypic and phenotypic correlations were observed between grain yield (kg ha-1 ) with panicle girth (cm),plant height (cm) and panicle length (cm).

Grain yield in rice is considered as a complex trait, determined by the ultimate expression of its individual component traits. Establishing an association between yield and its component traits plays a vital role in stabilizing the trait ‘overall yield’. Correlation and path analysis were examined in 46 rice genotypes including tropical japonica accessions, indica land races and elite indica cultivars as New plant type (NPT) core set along with checks during kharif 2017.
