The studies on the correlation of the traits and their relative direct and indirect effects on yield are important, as they are helpful to adopt suitable selection procedure for yield improvement in inter-racial breeding programmes. In the present study, 15 wide compatible genotypes (11 tropical japonicas and four indicas) were crossed with six non-wide compatible genotypes (three each of indic...

A study of genetic variation and interrelationship among grain yield and its component traits in rice (Oryza sativa L.) was carried out using 64 exotic rice genotypes. Maximum genotypic and phenotypic variance was exhibited by number of spikelets per panicle followed by plant height and days to maturity. The maximum GCV and PCV was exhibited by number of spikelets per panicle followed by number...

This study was carried out during the growing season 2020-2021 at two locations (Sumail and Zakho) to influence of different seeding (2,500000, 3000,000 3,500000 seeds.ha-1) DAP (0, 200, 300 kg.ha-1) rates on some early growth characters barley (Hordeum distichum L.) Triticale (X Triticosecale wittmack). The experimental designed as factorial three factors in a randomized complete block design ...

Sixty nine pearlmillet germplasm entries of diverse origin were evaluated for seven quantitative characters and three qualitative characters for their per se performance, variability and genetic divergence. Wider variability was observed for fodder yield and its associating characters along with crude protein content. The GCV estimates were observed to be high for number of leaves per plant, nu...

Understanding the patterns and drivers of carbon isotope discrimination in C(4) species is critical for predicting the effects of global change on C(3)/C(4) ratio of plant community and consequently on ecosystem functioning and services. Cleistogenes squarrosa (Trin.) Keng is a dominant C(4) perennial bunchgrass of arid and semi-arid ecosystems across the Mongolian plateau of the Eurasian stepp...

Weed competes with crops for water, nutrients and light so weed infestation is one of the major threats to crop. Present investigation was aimed to asses the comparative efficacy of different herbicides for weed management in wheat crop under agro-climatic conditions of Pakistan. This experiment was laid out in a randomized complete block design (RCBD) design with five replications. Different h...
