Sweet potato (Solanum tuberosum), a staple tuber crop in parts of the Sudan and Guinea savanna zone of Nigeria is known for its resistance to drought, vigorous early growth and low input requirements. Increase in population which has resulted to land shortages has led to reduction in traditional methods of maintaining soil fertility. Technologies based on combinations of organic and inorganic s...

Durum wheat is one of the most important cereal crops in Morocco. The development high-yielding varieties durum major goals breeding programs Crop genetic diversity should play an essential role this context. objective study was to assess variation among 280 accessions conserved at Moroccan Gene Bank by using twelve agro-morphological characters. All are planted field conditions and arranged au...

studies of genetic diversity of plant populations are very important tools for plant breeders. in this study, 110 rice genotypes, including 39 iranian local, 20 iranian improved and 51 foreign improved varieties were studied for 14 agronomic traits in the the rectangular lattice design at the rice research institute of iran (rasht). the analysis of variance showed that there were significant di...

combining ability effects were estimated for different agronomic characters in line × tester crossing program comprising 21 hybrids produced by crossing 7 lines and 3 testers. parents and hybrids differed significantly for general combining ability (gca) and specific combining ability (sca) effects, respectively. the variance due to gca and sca showed that gene action was predominantly additive...

Bambara groundnut has long been a neglected and understudied crop. Thanks to the new orientations for développement of agriculture achievement food security in Burkina Faso, recent years, studies on have experienced renewed interest. Despites nutritional, agronomic socio-economic importance some carried out this The diversity within cultivated remains poorly understood. objective study was asse...

The present investigation was carried out at Bihar Agricultural College, Sabour, Bhagalpur (Bihar) during the rabi, 2017-18 with eighteen genotypes including three checks, in order to identify high yielding stable linseed agronomic situations viz., Utera (sowing of seed before harvesting standing paddy crop utilize moisture efficiently under rainfed agro-ecosystem), Rainfed, and Irrigated condi...

For genetic improvement programs, researches with multivariate approaches in rice are fundamental, to define trends, clusters and correlations of agronomic characters that together help selection procedures. This work aimed reveal the performance, trends interrelationships grain quality based on models applied elite lines irrigated rice. The experiment took place 2017/2018 harvest, held at Esta...

Abstract Identification of genetic superiority is needed to anticipate problems such as local rice extinction and environmental stress due global climate change. This study aims determine the upland in South Sumatra, opportunities for its use a donor gene creation new high-yielding varieties. A research on eight was conducted May-September 2021. The method scope are inventory rice, identificati...
