Association Of Heterosis With Combining Ability And Genetic Divergence In Sesame (Sesamum Indicum L.)
Parental diversity is considered desirable to exploit heterosis in any breeding program. The present investigation was undertaken to search out whether any relationship existed between heterosis of cross combinations with phenetic divergence, combining ability and genetic divergence of parents in sesame. Seven sesame genotypes and their 21 cross combinations developed through half diallel matin...
متن کاملFloral Biology and pollination requirements of sesame (Sesamum indicum L.)
This study aimed to investigate the floral biology and pollination requirements of sesame (Sesamum indicum L.), cultivar CNPA G2. The study was carried out at Barbalha, State of Ceará, and consisted of two phases: floral biology and pollination requirements. Flowers were observed as for time of anthesis, lifespan and stigma receptivity, and were applied the following pollination treatments: ope...
متن کاملEvaluation of Traits Related to Drought Stress in Sesame (sesamum Indicum L.) Genotypes
In order to evaluate traits related to drought stress in eight sesame (sesamum indicum L.) genotypes, two experiments were carried out in randomized complete design with three replications in the field of the Research Station of College of Agriculture, Shiraz University, Iran. The two experiments differed with respect to their irrigation regimes. Yield related traits (number of days to maturati...
متن کاملMorphological evaluation of sesame (Sesamum indicum L.) varieties from different origins
Sesame (Sesamum indicum L.) is known as the king of oil seeds in Vietnam due to the high oil content (50 – 60%) of its seed. The purpose of this study was to evaluate morphology of sesame from different origins. Seventeen sesame varieties originating from El Salvador, Tanzania, Kenya, India, Cambodia and Vietnam were studied. The field experiment was carried out in the Mekong Delta region, Viet...
متن کاملDevelopment, inheritance and breeding potential of a recessive genic male sterile line D248A in Sesame (Sesamum indicum L.)
Genic male sterility (GMS) has great potential for heterosis exploitation in sesame (Sesamum indicum L.). Two spontaneous male-sterile plants were discovered in a Chinese sesame cultivar (Zhuzhi 4) in 2006. By consecutive sib mating with fertile plants from Zhuzhi 4, a new sterile line, D248A, was developed. Anatomy studies showed that D248A has thin, small and greenish anthers on which there a...
